Cooper Principle "!?" Interesting!

After more than a month of only BDG's, I am expanding to add other games of interest to me. Hopefully I can make it interesting to you! I love chess. I love writing. My intent to is do a blog post almost every day. I have lots of improvements planned, limited by my spare time. Since the days when Boris Spassky was World Champion 40 years ago, I have played over 41,000 games. The Blackmar-Diemer Gambit will always be popular on this blog. Right now I am trying to play a BDG every time as White, but that is not EVERY day. After all, half the time I play the Black pieces.

In the early 1970s I was working my way up through the bottom ranks of chess. My best opponent was the future master Graham Cooper. We played hundreds of blitz games in his dorm room during the 1972-73 college year. Graham taught me to play fast. He was much better than I was. Even though Graham played a lot of speculative sacrifices, he rarely lost on the board. I won about one fourth of the games; usually those wins were when his time ran out on the clock just before he mated me.

Cooper taught me to love chess books. He was a great student of the opening. He loved to attack. In addition to the King's Gambit, he played all the sharpest main lines of the 1.e4 openings. As Black he liked the Ruy Lopez Marshall Attack and the King's Indian Defence. Each week he would show me tournament games he recently played. He loved to sacrifice something in every game. We played about once a week. Constantly I prepared new lines from my own growing library to surprise him in our blitz games.

I learned three things from Graham Cooper about chess books.
1. Read chess books written in NOT IN ENGLISH! Graham had some King's Gambit books by Edwin Bhend in the German language. Sure books in English are easier for me to read, but Cooper read books from all over the chess WORLD as Bobby Fischer did.
2. Be CRITICAL of the moves the authors suggest. Walter Korn's MCO-11 was available at the time, but Cooper preferred MCO-10 by Larry Evans. His copy of that book had many notes scribbled in the margins with ideas from Cooper's games and analysis.
3. Look for the most INTERESTING moves. Cooper pointed out that in opening manuals like MCO, the best moves are indicated by "!" Graham said that the good players often knew the best moves. He liked to try all the interesting moves that had "!?" Those moves surprise opponents. That's what I call the "Cooper Principle"; it changed my chess life.

Spassky was a gambit player who beat Bobby Fischer in a Kings Gambit. Today's game is a King's Gambit Declined from the University of Maine Championship in 1972. The play by either side was not real accurate in this very short game, but I learned some important lessons. Defending open games requires exact opening knowledge. Good defensive possibilities are often overlooked. Boldness is frequently rewarded for gambits players.

Cooper (1900) - Sawyer (1450), UMO ch Orono, Maine (2), 09.12.1972 begins 1.e4 e5 2.f4 Bc5 3.Nf3 d6 4.Bc4 Nf6 5.d3 Nc6 6.Nc3 Bg4 7.h3 Bxf3 8.Qxf3 Nd4 9.Qg3 0-0 10.f5 Nxc2+ 11.Kd1 Nxa1 12.Bh6 g6? [12...Nh5! 13.Qg4 c6 -+] 13.fxg6 hxg6 [13...Nh5 14.Qg4 d5 15.gxf7+ Kh8 16.Qxh5 Qd6 17.Bxd5 +-] 14.Qxg6+ 1-0 Cooper,G-Sawyer,T/Maine 1972 Graham Cooper and I played hundreds of blitz games during the 1972-73 college year. He taught me a lot about studying openings and chess books. Cooper went on to be a Life Master. THREE THINGS I LEARN: 1. Defending open games require exact opening knowledge. 2. Defensive possibilities are often overlooked. 3. Gambits players are bold. 1-0

Pre-Moves and If-Moves - Blitz and Postal

On the day I played this game I went to McDonalds drive-thru to get a chicken sandwich meal. The person taking my money said they messed up recording my transaction and just to pull ahead and pick up my meal for free! If I had known they were going to do that, I might have ordered more! Sometimes your opponents just gives you stuff for free.

In the old postal chess and later correspondence chess by e-mail, it was common for players to speed up opening play by making "IF-moves." For example after 1.d4 one might offer "IF 1...d5 then 2.e4." White is bound to play 2.e4 only if Black plays 1...d5.

More risky are "If ANY" moves where one commits to a certain reply no matter what the opponent does. One might play 1.e4 and write "If ANY then 2.Nf3." That means White was committed to playing Nf3 on the second move no matter what. An attentive player with the black pieces might try 1.e4 d5 2.Nf3 dxe4, although this is a known gambit for which White might be prepared.

Some "If ANY" opening moves are no problem, such as 1.e4 c6 If 2.ANY then 2...d5." But these could go terribly wrong. For example after 1.d4 White could note "IF 1...ANY then 2.Bg5." All Black has to play is 1...e6 and 2...Qxg5 or 1...h6 and 2...hxg5.

Pre-moves are similar. They are common in online blitz chess. Late in the game they can be very helpful to speed up play when the clock is a big factor in the result of the game. Pre-moves work like this: You make a MOVE and while waiting for your opponent to move, you make a NEXT move. As soon as your opponent replies to your MOVE, then your NEXT move is instantly played as long as that move is still legal.

Pre-moves can be dangerous. One can always play pre-moves if your next move is FORCED. However you had better be CERTAIN that it IS forced. Pre-moves work well in endgames. In a bishop ending your opponent has a light squared bishop, you can often pre-move to a dark square that the bishop can never attack.

Today's game is a Dutch Defence vs a player whose blitz rating was almost the same as mine. Black will almost always play after 1...f5 the move 2...Nf6. This game began 1.d4 f5 (I surprised him with a Staunton) 2.e4 Nf6? (Whether or not Black has pre-moved this, obviously he had made up his mind to play 2...Nf6. How should White take advantage?)

Clearly 3.e5! is a good move. Black's best move is probably 3...Ng8 (not 3...Ne4? 4.f3 winning material). I did not feel like trying to only have a space advantage in a closed position. I grabbed the f-pawn. Now 3.exf5 d5 4.Bd3 e5?! (Black makes a practical choice to treat the position like a gambit. He opens up the game to let his bishops out.) 5.dxe5 Ne4 6.Bxe4 dxe4 (Good here is 7.Qh5+ g6 8.fxg6 with a big advantage. I decided to head for an endgame up a pawn or two.) 7.Qxd8+ Kxd8 8.Bg5+ Be7 9.Bxe7+ Kxe7. Here 10.Nc3! would have been better.

Eventually I let my advantage slip. It went from equal to me losing, back to equal and finally to me winning. My final move 54.c6+ was a pre-move.

Sawyer (1946) - bsireta (1898), ICC 3 0 Internet Chess Club, 29.07.2011 begins 1.d4 f5 2.e4 Nf6? 3.exf5 d5 4.Bd3 e5 5.dxe5 Ne4 6.Bxe4 dxe4 7.Qxd8+ Kxd8 8.Bg5+ Be7 9.Bxe7+ Kxe7 10.e6 g6 11.fxg6 hxg6 12.Nc3 e3? 13.fxe3 [13.Nd5+!] 13...Bxe6 14.0-0-0 Nc6 15.Nf3 Bg4 16.h3 Bxf3 17.gxf3 Rad8 18.Rxd8 Kxd8 19.f4 Ne7 20.Kd2 c6 21.Ne4 Nf5 22.Ng5 Ke7 23.Rd1?

Better Late Than Never to Find a Good Move

Tiger Woods is planning a comeback; hopefully his form will return. I have periods of time when I am not in good form. Such has been the case with me this week. After blogging that players of 3 0 blitz games have to play fast enough to last 60, 70 or 80 moves, I lost a game on time after 81 moves; my opponent played well and had 2 seconds left.

Seven blitz games a week are not enough to play oneself into great form. My results were only 3-2-2. I am choosing to spend most of my free time on other BDG projects at the moment. I hope to post more on those in about a month. Just a tease for now...

I plan to expand this blog to cover my thoughts about playing chess for 40 years regardless of what opening I played. The BDG makes up about 1/8 of my actual games. There will always be a heavy emphasis on the BDG because that has played such a significant part of my chess life. This makes 20 BDG blog posts in a row.

Today's game saw me accidentally playing a variation I rarely play. I was so committed to playing 4.f3 that I just let it go, even after Black had deviated from the main line. The game is a Blackmar-Diemer Gambit Avoided, Poehlmann Variation reached in the normal move order: 1.d4 d5 2.e4 dxe4 3.Nc3 f5 (This transposes to a Dutch Defence variation via 1.d4 f5 2.Nc3 d5 3.e4 dxe4; 3...fxe4 is a Staunton Gambit.)

Here I planned to play 4.f3 in response to 3...Nf6. Since it is a good line after 3...f5, I played it anyway. Most weaker BDGers prefer 4.f3 here. Usually I play Gedult's 4.Bg5 to "pin the imaginary horse". The best line in theory is 4.Bf4!; it is primarily the favorite of higher rated players of 2.Nc3 vs the Dutch for 20 years now. Junior 12 likes it too.

After 4.f3 exf3 5.Nxf3 e6 The game takes on the character of a Dutch Staunton. I like to attack e6 and potentially pin it with 6.Bc4 Nf6 7.0-0 Bd6 and now very strong for White is 8.Ng5! I played 8.Bg5 0-0 9.Qe2 Re8 10.Ne5 Qe7 missing for several moves that my pin already works now to regain the gambit pawn with 11.Rxf5!

I missed many tactical chances throughout the game, but I did keep attacking his king while playing rapidly. Eventually I found a mating combination to finish.

Sawyer-worldcitizen, ICC 3 0 Internet Chess Club, 28.07.2011 begins 1.d4 d5 2.e4 dxe4 3.Nc3 f5 4.f3 exf3 5.Nxf3 e6 6.Bc4 Nf6 7.0-0 Bd6 8.Bg5 [8.Ng5] 8...0-0 9.Qe2 Re8 10.Ne5 Qe7 11.Rad1 [11.Rxf5] 11...Nbd7 12.a3 b6 13.Kh1 Bb7 14.b4 a5 15.b5 Qf8 16.Rxf5 Kh8 17.Rff1 Re7 18.Ne4 Rae8 19.Nxd7 Rxd7 20.Nxf6 gxf6 21.Bxf6+ Kg8 22.Qg4+ Kf7 23.Qh5+ [23.Bh4+ Bf3 24.Rxf3+ Bf4 25.Rxf4#] 23...Kg8 24.Qg5+ Kf7 25.Be5+ Black resigns 1-0

Polish Problem: 1.d4 b5 Not Good

Most chess openings focus pawns and pieces on the center of the board. Repeatable direct threats among opposing armies make memorizing a few of the most popular variations worthwhile. This often leads to success as in the Blackmar-Diemer Gambit.

Flank openings have a big advantage in that any player who specializes in them does not have to learn many exact variations. Just the thought of not having to study openings appeals to many players. I have played these openings from time to time myself.

The problem with flank openings is the lack of central control. The player with more space naturally becomes the attacker; typically he has 5 ranks vs 3 ranks for the defender. The attacker can usually force open the position with a pawn push. A sudden appearance of open lines can be very challenging for the defender when the attacker is fully developed.

You must attack to win the game on the board. To win a game from a flank openings, you usually must neutralize the attack, gain the upper hand, start a counter-attack and then push it through. It is possible. But experience shows that the player who starts with an attack wins a lot more than the one who starts by defending.

In today's game, my opponent played a 54-move gambit! Okay, the OPENING was not a gambit. But the SPEED with which my opponent played made his game a gambit. Black consistently took three seconds or more for each move. Thus his three minutes expired before his 55th move. This approach requires one to win the game in 54 moves or less. If you play to WIN and if you are playing BLITZ chess, you must leave yourself enough time on the clock to be able to mate your opponent, no matter how long it takes.

The Polish Defence (reverse of Polish/Sokolsky 1.b4) begins 1.d4 b5 (1.e4 b5?? 2.Bxb5) 2.e4 Bb7 3.Bd3 (3.Nf3 Bxe4 4.Bxb5 is fine too.) 3...a6 (Reaching a St. George which usually begins 1.e4 a6). White has to make a set-up plan. 4.f3!? (BDG-ish) 4...d6 (more consistent is 4...e6). 5.Be3 e5 6.d5 (grabbing space and keeping Black cramped while White finishes development.) 6...Nd7 7.c4 b4 8.Ne2 a5.

Note that Black has played five of his first eight moves on the a- or b-files. 9.b3 Nc5 (Now I give Black one shot at Nxd3 swapping off my bad bishop. I want to play Nd2, but my queen must watch Bd3.) 10.0-0 g6 (Black switches to the other flank. I decide to unbalance by eliminating his knight in a closed position.)

As the game progresses Black trades his good bishop for my bad bishop in 18...Bxf5. He should have played the dynamic 19.Bxf5 gxf5! Late in the game both sides made blunders. My knight proved better than his bishop. My opponent allowed me to open up the position with his 40...h4? I missed 47.Nxe5+! By the time Black's time ran out, all White had to do was walk over and take on d6 followed by quickly queening.

Sawyer (1942) - El-Principiante (1809), ICC 3 0 Internet Chess Club, 25.07.2011 begins 1.d4 b5 2.e4 Bb7 3.Bd3 a6 4.f3 d6 5.Be3 e5 6.d5 Nd7 7.c4 b4 8.Ne2 a5 9.b3 Nc5 10.0-0 g6 11.Bxc5 dxc5 12.Nd2 Bd6 13.Rf2 Ne7 14.Nf1 0-0 15.Ne3 Bc8 16.Qd2 f5 17.exf5 Nxf5 18.Nxf5 Bxf5 19.Bxf5 Rxf5 20.Ng3 Rf4 21.Ne4 Qe7 22.Qe3 Raf8 23.Re2 h6 24.Rae1 g5 25.Qd3 Kg7 26.Ng3 Qf7 27.Re4 Qg6 28.Qe3 R8f7 29.Ne2 Rxe4 30.Qxe4 Qxe4 31.fxe4 Kg6 32.Rf1 Rxf1+ 33.Kxf1 h5 34.Ng3 g4 35.Nf5 Kg5 36.g3 Bf8 37.Kg2 Bd6 38.Kf2 Bf8 39.Kg2 Bd6 40.Ng7 h4 41.gxh4+ Kxh4 42.Nf5+ Kg5 43.Kg3 Bf8 44.Ne3 Bd6 45.Nxg4 Bf8 46.h4+ Kg6 47.Ne3?! [47.Nxe5+ would have decided the game almost instantly.] 47...Bd6 48.Kg4 Kh6 49.Nf5+ Kg6 50.Nxd6 cxd6 51.h5+ Kf6 52.Kh4 Kf7 53.Kg5 Kg7 54.h6+ Kh7 55.Kh5 Black forfeits on time. White still had 1:13 left on his clock. 1-0

When NOT to Resign a Chess Game

In the Maine State High School Championship for the year 1971-72, I finished 3-1-1. My draw was a pawn ending where I queened but could not figure out how to keep his b-pawn on the 7th rank from queening. Eventually I gave up, thinking the position could NOT be won; I let him queen and we swapped queens to draw. A few months later I was laying in bed one morning before school when all of a sudden the winning method came to me.

Ever make a really bad move only to have your opponent resign? Yes, my games sometimes conclude in the most interesting ways. I have resigned in drawn positions and taken draws in winning positions. These blunders happen when players DO NOT THINK the game can be saved or can be won. It is always a little embarrassing to find this out later on. I once played a BDG where we were both embarrassed.

My opponent was Mr. Bender. Back in the 1970s there were two Benders in APCT. I played a King's Gambit vs Sam Bender who was rated about 100 points below me. On his last postcard, after making his move he wrote, "Looks like you got me." Friendly chit-chat or banter was common on postcards during games. A week or two later I got a card from his wife informing me that Sam had died.

It is rare in the USA to win a chess game because your opponent dies. However it was certainly more common during old postal chess games that might take a year vs during over-the-board games that might take hours. I seem to recall an old tale of a postal player in Connecticut who died without informing his opponents. The long time postal chess tournament director I.A. Horowitz secretly took over the games and won the tournament!

My BDG Bender was against Fred Bender. We met in various Master/Expert sections. Eventually Fred became a very strong postal master. I was the expert. We were paired together in four events over the span of a dozen years. The first game I lost as Black in a Sicilian Rauzer Defence. The second game I was White in a hard fought Sicilian Dragon draw. The final game I was Black; he outplayed my Caro-Kann Defence.

Our third meeting is today's BDG. After 1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bh5 (While somewhat illogical, this retreat is theoretically sound. In Purser's BDG WORLD, March 1989, I wrote that "6...Bh5 is the best move here, although Gunderam recommends 6...Bxf3 in his 1986 book on the BDG.". Black may think he is tempting White to weaken himself, but he is usually in for a surprise.) 7.g4 Bg6 8.Ne5 ("with excellent prospects for White." [Horowitz]) e6 9.Bg2 (9.Qf3 is played twice as often, but both moves are good.) and now with 9...Nd5 Bender leaves the worn path of 9...c6.

For the rest of the game, my favorite move was 13.Bg5!? I wish I thought of moves like this in every game! Gradually I got the better position and wore Bender down. By the time I played my final move 24.Rff7?? (24.h4 wins), he had probably figured the game was over and he resigned without noticing that he wins after 24...Qxf7! "No one ever won a game by resigning." I.A. Horowitz

Sawyer-Bender, corr APCT, 1985 begins 1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 exf3 5.Nxf3 Bg4 6.h3 Bh5 7.g4 Bg6 8.Ne5 e6 9.Bg2 Nd5 10.0-0 c6 11.Nxg6 hxg6 12.Qf3 f6 13.Bg5 Qb6 14.Nxd5 cxd5 15.Bxf6 Qc7 16.Be5 Qd7 17.Qd3 Nc6 18.Qxg6+ Kd8 19.Rf7 Ne7 20.Qg5 Rg8 21.Raf1 Qe8 22.Bxg7 Bxg7 23.Rxg7 Kd7 24.Rff7 1-0

My First Blackmar-Diemer Gambit Experience

On a cold snowy night in a little white building behind the YMCA, about a dozen players enthusiastically met for chess. Years later the Lansdale club would grow significantly and move to a larger location. How many of us have played in little clubs all over the world? What if I had not shown up that night? A bit of history would have been missed.

At my day job I was working in a department store and going to school. It was the busy Christmas season, but I was off on nights the chess club met. During lunch breaks at work I would bring my old magnetic chess set and play through games from a book. That helped give me an intuitive feel for where the pieces go.

As a universal player of openings, I am always studying something. A favored opening of mine has been the Gruenfeld Defence. I like the wide open piece play and the tactics. The same can be said about the Catalan and the Alekhine Defense. They were not so popular 30 years ago and they rarely lead to early kingside attacks. In these openings I try to keeping winning more material by combinations and to convert that into either a winning endgame or shift the attack to a weakened king.

Chess Digest out of Dallas, Texas was the source of many of my books. When customers bought enough, Ken Smith let them choose something extra from his free book list. I picked up a copy of "Discover the Blackmar-Diemer Gambit, Volume 4, Bogoljubow Defense" by Nikolajs Kampars & Anders Tejler. The 5...g6 line seemed to fit well with my Gruenfeld set-up. I managed to play through the 100 games in the book, a few at a time, over a period of many weeks.

I was still working my way through that book at the time today's game was played. Glenn Snyder was not someone I knew well, though it was a small club. We would play only one other time that I have recorded. Three months later I would be White in a Bishop's Opening that transposed into a King's Gambit Declined. In that game I won a pawn on move 10, swapped off all the pieces and eventually won the pawn ending.

Snyder's choice of the BDG probably came as a surprise to me. I am very thankful for his bold choice. I decided to play the BDG Bogoljubow since it fit my prepared defensive system. The club games were slower, so I had time to think. This game began 1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 (A few years before I had avoided a possible BDG by ducking into a French Defence with 3...e6 only to be outplayed in a line I did not know.) 4.f3 exf3 5.Nxf3 g6.

The game did not follow critical theory after 6.Bg5. I remember thinking White's position looked pretty good to me. As the higher rated player, I expected to win. Snyder was rated in the 1700s. During the game I thought that if my opponent had been stronger, I could have faced much more pressure on the board. For example, finishing his development by attacking my e-pawn with 12.Rae1! would have been a nice try. The old saying is, "If you don't use, you'll lose it." That's what happened to the rook on a1.

[Note: I do not believe there is any relationship nor connection between Glenn Snyder, who seemed like a fine and decent person, and the imfamous Robert M. Snyder.]

Snyder-Sawyer, Lansdale,PA, 12.12.1980 begins 1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 exf3 5.Nxf3 This was the first time I entered a Blackmar-Diemer Gambit. 5...g6 I played the Gruenfeld a lot, so this was a natural choice of defence. 6.Bg5 Bg7 7.Bc4 0-0 8.0-0 Bg4 9.d5!?

Space Shuttle French Defence Checkmate

This morning I went out to watch the final landing of the final Space Shuttle. It was like looking for a black bullet shooting across a darkened sky. I didn't see a thing. After it zips by there are two identical loud firecracker-like noises that shake the buildings, each about one second apart: "BOOM, BOOM." That is like a typical Mate In Two. Today's game ends with such a checkmate. We love mates in the Blackmar-Diemer Gambit!

This has been a positive week for me in my games. I played 10 different opponents. All who accepted my 3 0 ICC challenges were rated below me. My score was 8-1-1. I should have lost the game I drew when his flag fell. My loss was a likely win on time that I let get out of hand. All total my rating did inch up a little. Every day I play at least one human. Beyond play I am working on a separate BDG project for later in the year.

Our game begins 1.d4 d5 2.e4 dxe4 3.Nc3 e6 (Back in a French Defence) 4.f3 Nf6. Now we arrive by transposition to the Weinspach Variation which is a popular BDG Declined variation where usually Black reverses the 3rd & 4th moves. Play continued 5.fxe4 Bb4.

Six 6th moves are reasonable for White. This time I chose the most popular 6.Bd3. Quite playable is 6.Qd3!? Less good are 6.Bg5, 6.e5 and 6.Nf3. Finally we come to 6.a3 Bxc3+ 7.bxc3 which curiously transposes to the promising Winckelmann-Reimer Gambit vs the French Winawer. The normal move order for the WRG is 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.a3 Bxc3+ 5.bxc3 dxe4 6.f3 Nf6 7.fxe4.

After the sharp 6.Bd3!? Black has a tactical shot 6...Nxe4! 7.Nge2 "Apparently the only possibility." - Dr. Grava [Blackmar-Diemer Gambit, Dec 1962]. White must guard against both the check on h4 and a double capture on c3. The toughest defence seems to be to retreat the knight, but Nf6xe4-f6 is rarely played by those rated below me.

My opponent now embarked on setting up a solid looking position for the next few moves and ignoring my threats. He played 6.Bd3 0-0?! 7.Nf3 (I feel much better now.) 7...c6?! 8.0-0 Qe7?! 9.Bg5 (or even 9.e5) 9...Nbd7? 10.e5 and White has won a piece. Rather just try to win on material, I decided to play for the "BOOM, BOOM!"
