Albin Counter Gambit Kingside Assault

Aggressive play with the Black pieces can leave White feeling uneasy and conflicted. White thinks HE should do the attacking, but instead he finds himself on the defensive. Often to accomplish this Black may play a gambit. In this Albin Counter Gambit variation vs "ambro1957", both sides are on their own fairly quickly. My dubious move 7...Be6?! gave White chances that were missed. Then I built up a strong kingside attack.

Spanish Four Knights to Ruy Lopez

Ever been fooled into transposing from one opening to another? Openings have very specific move orders that reach certain positions. Early moves in Closed 1.d4 openings where White intends to play d4/c4/Nf3 can be played in any order. The Open 1.e4 lines require a more exact approach. The first move 1.Nc3 has many transpositional options where White can flip into popular openings or stay with lines original to 1.Nc3.

Below with 1.Nc3, I transposed from a Queens Knight Attack to a Vienna Game to a Four Knights Game to a Ruy Lopez. After 1.Nc3 e5, over 400 times I have chosen the Napoleon move 2.Nf3 attacking e5. For this game I chose the more conventional 2.e4.

A common Ruy Lopez move order is 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nf6 4.0-0 d6 5.d4 Bd7 6.Nc3 exd4 7.Nxd4 Be7. In my ICC blitz game vs "catz" (rated 1585), I won a piece for a pawn and gradually strengthened my position until he ran out of time.

Win my Sawyer French Variation

Back when I invented the French Defence Sawyer Variation (4.Bg5) 20 years ago, my goal was to transpose into a Blackmar-Diemer Gambit Euwe variation as I showed in an earlier posting. However, Black does not have to capture my f3-pawn immediately. Here my ICC blitz opponent "Muravey" (1773) kicks my bishop from g5 and I redeploy to Be3.

Anyone who plays the Blackmar-Diemer Gambit type positions should be very aware of possible tactics involving the Bxh6 sacrifice, especially if Black has castled kingside and played ...h7-h6. Here light squared bishops have been exchanged, but the sacrifice is still promising due to White's very active pieces which target the Black king. White follows up the Bxh6 sacrifice with an attack using his queen, knight and rook.

Sawyer-Muravey, ICC 3 0 Internet Chess Club, 06.02.2013 begins 1.d4 Nf6 2.f3 e6 3.e4 d5 4.Bg5 Sawyer Variation 4...h6 5.Be3 dxe4 6.Nc3 exf3 7.Nxf3 b6 8.Bd3 Bb7 9.0-0 Bb4 10.a3 Bxc3 11.bxc3 0-0 12.Qd2 Ne4 [If 12...Nbd7 then 13.Bxh6 still follows.] 13.Bxe4 Bxe4 14.Bxh6 gxh6 [Maybe 14...Nc6 15.Rae1] 15.Qxh6 Bg6 [15...Bxc2 16.Ne5+-] 16.Ne5 [Houdini 3 gives 16.Nh4+- as more accurate.] 16...Bf5?

Haines vs Morin Sicilian 5.Bc4 Gambit

A couple weeks ago during a high school chess tournament in Presque Isle, Maine, while the younger generation was duking it out in longer games, the veteran players Ray Haines and Roger Morin played a lively 10 minute game for fun. Ray Haines discusses his choice of one of his favorite gambit lines - which I learned from him. That is the Sicilian Defence with 5.Bc4. Ray wrote:

"I have been playing this line in the Sicilian defense against the computer and most of the lines are equal or better for white. I came up with the line a long time ago and showed you it then. You won a postal game with it. I am planning to use it in tournaments,because it will get people out of the lines which they know, quickly. I think it is worth using. I would never have thought of using it without the computer to help me."

Todd Defeats My Latvian Gambit

The main line Latvian Gambit leads to a position where the White pieces stand very well, but Black regains the pawn. Furthermore, the slightest White inaccuracy allows Black an aggressive unbalanced position where chances are roughly equal. Below is my game vs TE Todd played in the 1989 USCF Golden Knights Postal Chess Tournament.

Here I got a great position as Black with an advantage for about 10 moves. Houdini says I stood much better until I carelessly blundered a piece to a combination on move 33. Ugh!

My 150 Attack Stephen Ashby Pirc

My most popular posting was How To Win With the 150 Attack vs the Pirc Defence published September 3, 2011. Today's game is in the same Pirc Defence 4.f3 variation. Back in 1990 it was rare. Sometimes White reverses the move order with 4.Be3 and 5.f3.

In theory it is more risky for Black to castle too early, so often plays 5...c6. This game is broken off early, but I am not sure if it was a resignation or forfeit. In any case, my chess engine program Junior 10 today evaluates the position as strongly favoring White.

This victory over Stephen Ashby (1848) brought me to my peak USCF correspondence rating of 2211. After this game I won about five more games in a row, but the USCF refused to give me any rating points for any of those wins.

Sawyer (2211) - Ashby (1848), corr USCF 89N280 corr USCF, 14.05.1990 begins 1.d4 d6 2.e4 Nf6 3.Nc3 g6 4.f3 Bg7 5.Be3 c6 6.Qd2 Nbd7 7.0-0-0 b5 8.Bh6 0-0 9.h4 Qc7 10.h5 Bxh6 11.Qxh6 b4 12.Nce2 Qa5 13.hxg6 fxg6 14.Kb1 [This game brought me to my peak USCF correspondence rating of 2211.] 1-0

BDG Mail Dr. Rimvydas Sidrys

In 1989-1990 I played chess against Dr. Rimvydas Sidrys who passed away in 2010. His family did a nice tribute to Dr. Rimvydas Sidrys from where I note this excerpt:

"He rode an English racer bicycle to work in the 1970s before it was common for adults to ride bicycles in the United States. He loved chess and would play chess by mail. He would spend his lunch hour in front of a chess board planning his next move and send it on a postcard to his opponent."

Our game was a Blackmar-Diemer Gambit Bogoljubow played in the 1989 USCF Golden Knights Postal Tournament. I am sure the good doctor played more than 11 moves in most of his games. The BDG is contains tricky tactical threats against common moves typical of good players. Dr. Sidrys had developed both knights, castled and was in the process of a second bishop fianchetto when he gets caught in a combination.

Sawyer (2174) - Sidrys (1660), corr USCF 89N280, 29.01.1990 begins 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 g6 6.Bc4 Bg7 7.0-0 e6 It is very dangerous for Black to play ...e6 in the Bogoljubow Variation because of the weakness it creates on f6. 8.Bg5 [8.Qe1 Ng4=/+] 8...0-0 9.Ne4 [This seems even better than 9.Qe1 which transposes to 7...0-0 8.Qe1 e6 9.Bg5 to BDG Keybook Game 457] 9...Nbd7 10.Ne5 Black loses a piece. 10...b6 [10...Nxe5 11.Nxf6+ Kh8 12.dxe5 Qe7 13.Qd4 Rd8 14.Qh4+- Wundt] 11.Nxd7 1-0
