King's Indian Saemisch 1.d4 Nf6 2.f3

After my win in yesterday's post, Roquentin naturally wanted another crack at me. So we turned the board around and played again. I took a shot at a Blackmar-Diemer Gambit with the Paleface Attack 1.d4 Nf6 2.f3!?, but Black played 2.c5 (2...d5 3.e4 dxe4 4.Nc3 is a BDG). The position transposed from a Benoni into a King's Indian Saemisch variation. [Speaking of Benoni, here's a trivia question: What actress is from Benoni, South Africa?]

This King's Indian Defence game differs from the normal 5.f3 line in that I played my dark squared bishop to Bg5 instead of the common Saemisch Be3. The reason is that once the moves ...c7-c5 and d4-d5 have been played, there is no pawn on d4 for White to defend. This line is solid with the pawn on f3 protecting e4. However it takes White longer to unfold his kingside pieces. The f3 move contributes to safety but not activity. You need both. The note beginning with 8.Qd2 below is a good suggested plan.

Chances are basically equal as far as long term results are concerned. Those who play the line frequently will benefit from experience and score better than half. If you do not like this as White, alternatives for BDG players are 5.Nc3 Benoni Schmid or 2.Nc3 which could lead to 2...d5 3.d4 Nxe4 (Huebsch) or 3...dxe4 4.f3 (BDG).

Queen's Knight Defence Plays Like King's Indian

The Queen's Knight Defence is very flexible. Here is the Mikenas Variation (3.d5 Nce7) with c4 thrown in. This is the reverse of a Queen's Knight Attack Van Geet (1.Nc3 d5 2.e4 d4 3.Nce2. The Queen's Knight player has two popular set-ups after Nc6-Nce7 or Nc3-Nce2. One is to play ...Ng6 or Ng3. The other is to keep the knight on the e-file for the moment to support ...f5 as Black or f4 as White. My choice depends on my mood.

In this game I turn it into a sort of King's Indian Defence with 8...g6 using the open f-file, e-file and long dark diagonal. My opponent Roquentin (2150) attacked aggressively, but my pieces were better placed and my king safer. Thus the tactics flowed in my direction.

Roquentin (2150) - Sawyer (2013), ICC 3 0 u Internet Chess Club, 31.05.2013 begins 1.c4 Nc6 2.d4 e5 3.d5 Nce7 4.e4 f5 [4...Ng6 5.Nc3 Nf6 is much more popular.] 5.Nc3 Nf6 6.exf5 Nxf5 7.Nf3 d6 8.Bd3 g6 9.Bg5 [9.0-0+/= is a good move, but White wants more.] 9...Bg7 10.Qc2 0-0 11.g4?

Brian Harper Goes Postal Benoni Defence

A knock at my motel door. "Brian?" "Tim?" "Come on in." I was in Columbus on business in 1991, home of Ohio State University. When I was a kid, I always thought that Cleveland and Cincinnati must be the largest cities in Ohio because of their professional sports teams. The 2010 census indicates Columbus is larger than both the others combined.

I played six games vs Brian Harper from 1990-1992. Every one of them was a Blackmar-Diemer Gambit except this one game below. We first met in some BDG thematic postal tournaments. At least one event was run by Tom Purser for readers of his Blackmar-Diemer Gambit World magazine in which we agree to short draws, one with each color. In another correspondence game I had won as White vs Brian in 27 moves.

Brian and I were sending chess moves by postcard about once a week for more than a year altogether. When I found out I was going to be in Columbus for a couple days with a free evening, I mentioned it to Brian. We arranged to meet. I have pleasant memories of a nice evening mostly talking chess. As I recall, we did play a couple 5 minute games, both of us winning BDGs quickly as White when Black blundered away a queen.

The Benoni Defence 2.f3 is a clash between styles when I give Black the chance to transpose back into a BDG (2...d5 3.e4 dxe4 4.Nc3). Here in a 1989 USCF Golden Squires Postal Tournament we end up in a fairly orthodox position (4.c4). We both get into trouble on the board playing normal moves, such as 18.Bh6? and 21...Qh4? The strategy was good but the tactics were bad. Fortunately for me, he made the last mistake.

Leslie Ward in English Opening Dutch

The Dutch Defence is a universal system that can be played against virtually anything except 1.e4. Here against Leslie V. Ward in the 1989 USCF Golden Squires Postal Chess Tournament we reach what is a Closed English (or Closed Sicilian reversed).

In this English Opening, a fight breaks out on the f-file, but the position stays relatively closed. Gradually I picked off a couple pawns. When Ward resigns, he writes: "Your two pawns in open files should be good enough to win without much trouble."

Ward (1792) - Sawyer (2013), corr USCF 89SS60, 01.04.1991 begins 1.c4 f5 2.g3 Nf6 3.Bg2 g6 4.Nc3 Bg7 5.d3 d6 6.e4 Nc6 [The most common line here is 6...e5 7.Nge2 Nc6 8.0-0 0-0 9.Nd5 Be6 10.Bg5 Qd7 11.Qd2=] 7.Nge2 0-0 8.h3 e5 9.0-0 Be6 10.Nd5 Ne7 11.Bg5 c6 12.Nxf6+ Bxf6 13.Bxf6 Rxf6 14.exf5 Nxf5 15.Nc3 Nd4 16.Ne4 Rf8 17.b3 Qe7 18.Rc1 Kg7 19.Rb1 h6 20.Rb2 Rf7 21.b4 Raf8 [21...Bf5=/+] 22.c5 Bd5 23.cxd6 Qe6 24.a3 Nb5 25.a4 Nxd6 26.b5 Nxe4 27.dxe4 [27.Bxe4 Qxh3 28.bxc6 bxc6=/+] 27...Bc4 28.Re1 cxb5 29.Rd2 [29.axb5 Qb6-/+ gaining time by hitting f2.] 29...Bb3 30.Rd6 Qc4 [Swapping queens is the strongest for Black with 30...Bxd1 31.Rxe6 Bxa4-+] 31.Qg4 Rf6 32.Rxf6 Rxf6 33.Qd7+ Rf7 34.Qxb5 Qd4 35.Re3 Bxa4 36.Qe2 [36.Qa5 b6-/+] 36...Rd7 37.f4 Qd1+ 0-1

Dyba Battles French Alapin Gambit

My French Defence Alapin Gambit Declined 4.e5 game vs Paul R. Dyba was one of the 52 annotated games [Game 19] in my 1995 Alapin French book published by Bob Long and Thinkers' Press. Below is the actual move order of our 1989 USCF Golden Squires Postal Chess Tournament game. In the book I followed a different move order of 1.e4 e6 2.d4 d5 (and later 7.Nf3 Be7 8.h4 Qb6 9.Qd2 cxd4 10.cxd4 f6 from the Diemer-Busca game given in the notes below). All this transposes to my game with Paul Dyba.

In the book I analyzed the variation using a consistent move order between games 18-20 to help the reader to compare subtle differences, knowing that there are many paths to the same positions. Moves 12-16 below imply a willingness for both players to draw the game. At this point we were both probably out of contention for any prizes. The notes below are revised for this blog post with the help of computer analysis not available back in 1991.

Sawyer (2006) - Dyba (2019), corr USCF 89SS60, 31.12.1991 begins 1.d4 e6 2.e4 d5 3.Be3 Nf6 4.e5 Nfd7 5.f4 c5 6.c3 Nc6 7.Nf3 Qb6 8.Qd2 f6 9.h4!?

After Black castles there might be a possible Ng5!? sacrifice to open the h-file. 9.Be2+/=] 9...cxd4 10.cxd4 Be7 11.Nc3 0-0 [This is more sensible than opening lines by 11...fxe5 12.fxe5 0-0 13.0-0-0 Bb4 14.Ng5 Ne7 15.Bd3 Nf5 16.g4 h6 17.gxf5 hxg5 18.fxe6 Nxe5 19.dxe5 Qxe6 20.hxg5 Qxe5 21.Bd4 Bxc3 22.Bxc3 1-0.

Myers in BDG: How Much Can I Sac?

In correspondence chess it is possible to play brilliant exciting chess with little or no effort on your part at all! My Blackmar-Diemer Gambit game vs William Myers from the 1989 USCF Golden Squires Postal Chess Tournament in 1990 was such a game. We followed the 1970 thematic postal game Roald Berthelsen-Newton Grant to 22.Nce4 1-0! Since using chess books during the game was permissible, the first 22 moves were easy for me.

One thing that makes this BDG Bogoljubow game interesting is contrast in strategic plans. Already up one pawn (3...dxe4), Black delays the development of his Nb8 to go after a second extra pawn (9...Bxc2). Meanwhile, White develops a mating attack.

Another interesting thing is the comments provided on postcards by my friendly opponent, William Myers. Would I need to resort to a perpetual check draw to survive being down 2 pawns? Sometimes White has to do that. I used my multiple sections of postal games (often playing 50-60 games at once) to learn the BDG. In my "Blackmar-Diemer Gambit Keybook" (1992) this is Game 468. The notes below have been updated for this blog post.

Sawyer (2062) - Myers (1872), corr USCF 89SS60, 05.06.1990 begins 1.d4 Nf6 2.f3 d5 3.e4 dxe4 4.Nc3 exf3 5.Nxf3 g6 6.Bc4 Bg7 7.0-0 0-0 8.Qe1 Bf5 9.Qh4 Bxc2 10.Bh6 Bxh6 11.Qxh6 e6 [11...Bf5 12.h3!?=] 12.Ng5 Qxd4+ 13.Kh1 Bf5?

Myers] 18.Be4+ Kg8 19.Rd1 Qf2 [Black can only squirm for a little while.

Impression of Blackmar-Diemer Rasa

In BDG Magazine April 1962 we read: "Robert Rasa, after winning a cup at the chess championship tourney in New Zealand, as a runner-up, praises Blackmar-Diemer Gambit."

"MY IMPRESSION OF BLACKMAR - DIEMER GAMBIT..."
     "The first time I was confronted with a B/G Gambit wasn't over the chessboard, but in print. It was one of Diemer's earlier publications to his so-called B/D Gambit "Parish" - a group of chessplayers from Holland, Germany and Austria, who joined forces in order to look for new ways of brightening up the game of chess.
     "All this appealed to me very much and I joined the group - and never regretted it.
     "I was fortunate to be able to supply one or two new lines in certain variations of the attempted revival of the Blackmar Gambit. This was much fun, plenty of excitement and none of the dullness and stuffiness of the purely theoretical analyses. This is living chess, attractive in the variety of possibilities, refreshing in the approach.
     "Above all, I came to know the man behind it - the excitable, likable, original personality of Joseph Diemer. Because of his exaggerated, pompous style of writing, he soon got himself in hot water with other chess writers.
     "Diemer, however, is at all times an honest, frank and straightforward man, and lives up to his writings. He practices what he preaches - no matter what the consequences.
     "They call him "Ritter ohne Furcht" and rightly so. Often misunderstood, wrongly attacked - mostly by his own countrymen - he went his own inimitable ways - in chess as everywhere else. It irritates me very much, that people, who haven't done much themselves towards the game of chess, sling mud at good sports like Diemer, who practically sacrifice their personal lives for it.
     "Sure enough - we need all sorts of people to make a world, but as far as chess is concerned it's people like Diemer, who constantly strive to make it brighter and more interesting. It is not so far back, when Capa made his gloomy prediction that this game we all love so much will end in a death of draws...
     "It seems so odd and futile, that in face of that, many so called theoreticians are so eagerly engaged constantly trying to refute every fresh effort to liven up the game. This fate befell also Diemer's enthusiastic undertaking to induce new blood and ideas with his B/D Gambit into the game. As soon as the complex of B/D Gambit openings came in to some sort of semblance, came to pack of "Theoreticians" -  in full cry competing against themselves for a "refutation"... Now, some of them - including his former co-worker Gunderam - gleefully claim having found it?! OK! So, now what?
     "Let's stop playing chess and all of us join in the fun (?) searching for refutations of the remaining few playable openings we have left. When we have succeeded in that, then let's make a monumental funeral to the game of chess and start playing - say, marbles... Let's hope neither Pachman, Mueller, Gunderam nor the rest of them will be interested to find refutation to my pink marbles knock against your blue ones.
     "However, since players like the late Alekhine, Lasker, Spielman and present Tal, Fischer, Larson, Olafsson and such like keep cropping up, we still have some hope left, that the game will survive, in spite of the hord of "researchers" trying to refute it."
     R.A. Rasa - Dunedin, New Zealand
                                                            *****
Below is a BDG Declined 4.f3 e6 game with notes from the February 1962 issue.
                                                            *****
"A fascinating game of a King-side attack was recently played by Robert A. Rasa."

Robert A. Rasa - R.W. Lungley, Dunedin, New Zealand 1961 begins 1.d4 Nf6 2.Nc3 d5 3.f3 e6 4.e4 dxe4 5.fxe4 Bb4 6.Bd3 0-0 7.Nf3 c5 8.0-0 cxd4 9.e5 Ng4? 10.Ng5 f5 11.exf6 Nxf6 12.Rxf6! [Beautiful!] 12...Qxf6 13.Bxh7+ Kh8 14.Nce4 Qe5 15.Qh5 Black resigns 1-0
