Alekhine Jonathan Schroer Tim Sawyer

Today I finish up my month of simultaneous exhibitions with a game I played against Jonathan Schroer on the Internet Chess Club. Schroer earned the FIDE title of International Master in 1984. He is a skilled attacking player.

IM Schroer is a great blitz player who has played many online simuls. The game today was played at a pace of 35 35 (35 minutes for each sides for the game, plus an additional 35 seconds increment added after each move is played. Ten years ago when this game was played, Jonathan Schroer had an ICC rating of 2708. My rating was 2232. I do not know how many other boards Schroer was playing at once.

For our game I chose the Alekhine Defence. This was not too long after I had written my Alekhine Defense Playbook, so the variations and analysis were fresh in my mind. I had played more than 1200 games with that opening. Nowadays I have played twice as many.

Currently my personal contests of the Alekhine Defence of 1.e4 Nf6 with me as Black total 2424 games. My most common defence is the Open Game 1.e4 e5 (2691 games), but I have played both the Queen's Knight Nimzowitsch Defence 1.e4 Nc6 and the solid Caro-Kann Defence 1.e4 c6 more than 1300 times each.

Schroer-Sawyer, ICC 35 35 u Internet Chess Club, 26.11.2002 begins 1.e4 Nf6 2.e5 Nd5 3.d4 d6 4.Nf3 Bg4 5.Be2 c6 6.c4 Nb6 7.Nbd2 dxe5 8.Nxe5 Bf5! [Up to this point Schroer was playing fairly rapidly against me. This 8...Bf5 variation is given in my "Alekhine Defense Playbook". White seemed to be surprised by this move. He used about 30 minutes for his next two moves. In his book on the Alekhine Defence, Nigel Davies only considered 8...Bxe2 9.Qxe2 Qxd4 10.Ndf3 when White has a strong attack.] 9.c5N [The line given in my book continues: 9.Nb3 e6 10.0-0 Be7 11.a4 N6d7 Usually it is in Black's interest to challenge any White piece on e5 and swap it off if possible. 12.f4 Nxe5 13.fxe5 Bg6= 0-1/30. Popovych-Szmetan, World Open 1999] 9...Nd5 [In view of the fact that I am behind in development I aim for safety and happily return to the hole White created on d5. Since White spent so long on this 9th move, he must have been prepared for the obvious 9...Qxd4 10.Nxf7 Kxf7 11.cxb6 Qxb6 when clearly White has a lot of compensation for the sacrificed pawn. It will take a few moves for White to complete his development, but the Black weaknesses of his e-pawn and king cannot be covered up that quickly.] 10.Ndf3 Nd7 11.Nc4 e6!? This is a risky continuation because it leaves a big hole on d6. I decided to risk it so as to complete my development. At least this way my bishop covers d6. 12.0-0 Be7 13.Re1 0-0 14.Bd2 Qb8!? [14...b6! seems to be the most aggressive continuation. I considered it, but decided not to mix it up with an IM whose tactical skills exceed mine. He had less than two minutes left on his clock while I had about 30 minutes, but there is a 35 second increment. I decided that I would force White to come up with a plan and a combination while his clock was ticking. 14...Qc7 is the most natural move.] 15.Rc1 Bg4 16.h3 Bxf3 17.Bxf3 Re8 18.Qb3 Qc7 19.Red1 White waits for Black to force the issue and create a weakness that he can attack without deep thought. We both decide to wait for a mistake and repeat the position three times. 19...Rac8 20.Re1 Ra8 21.Rcd1 Rac8 22.Rc1 Ra8 Game drawn by repetition 1/2-1/2

Chandler Mates in Blackmar-Diemer

As previously noted, this year I am adding other people's games to my blog. If you would like me to ANNOTATE YOUR GAMES, SEND THEM to my e-mail address at: sawyerte@yahoo.com. Today we have another game by William Chandler.

Bill sent me this little game that illustrates one reason we play the Blackmar-Diemer Gambit. What other opening are you likely to play where you checkmate your opponent on move 14? Once again Bill Chandler is using the ICC handle "ProjectAlpha".

The opening transposes into the Blackmar-Diemer Gambit Accepted, Euwe Variation reached by 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 e6. This line is very popular. Masters recommend it for Black. BDGers like it as White, because it is easy for Black to blunder and get mated in short order. Today's game is a good example of that.

ProjectAlpha - NIMZO81, ICC 5 0 Internet Chess Club, 02.01.2012 begins 1.d4 d5 2.Nc3 Nf6 3.e4 [A major alternative for those who do not want to gambit is 3.Bg5, the Veresov.] 3...dxe4 4.f3 exf3 5.Nxf3 e6 BDG Euwe Variation 6.Bd3 [Probably the best move order is with 6.Bg5 Bb4 7.Bd3 Nc6 but in this case, the same position would be reached as in the game.] 6...Nc6 7.Bg5 Bb4 This is almost always a mistake in the BDG. In this game it is a waste of time as Black just returns to the better location Be7 next move. In other games Black captures ...Bxc3 and bxc3 strengthens the White d4 pawn. 8.0-0!? [Offering to sacrifice the d4 pawn, similar to the Zilbermints Gambit {there Black plays 6...Be7}. White could try 8.Qd2 or 8.a3 ] 8...Be7 [If Black grabs the pawn with 8...Nxd4 then 9.Kh1! gives White some compensation for the two extra Black pawns.] 9.Qe1 Nd5 10.Bxe7 Qxe7 11.Ne4 [11.Qg3!+/-] 11...0-0 12.Neg5 Nf4? [Black had to try 12...h6! ] 13.Qh4 [More accurate is 13.Bxh7+! Kh8 14.Qh4 with mate in a few moves.] 13...Ng6? [13...h6 14.Qxf4 hxg5 15.Nxg5+-] 14.Qxh7# Black is checkmated 1-0

Chandler Beats Blackmar-Diemer Avoided

Starting this year, 2012, I have decided to annotate not just my own games, but also YOUR GAMES, IF you SEND THEM TO ME. If I find something about any of your games that interest me, I will post them with my notes, or maybe your notes. It is easiest if you sent the games in CBV or PGN format. E-mail games to: sawyerte@yahoo.com

I like all openings, so send me whatever you have. I started this on January 1st with a game by Jocelyn Bond. Recently William Chandler also sent me a few of his Internet Chess Club blitz games. I continue with two Blackmar-Diemer Gambits that Bill played on January 1st and 2nd. One I post today and the other tomorrow. Later I may post some non-BDG games that Bill Chandler sent me.

Today's game is an endgame win for White. This game begins 1.d4 Nf6. White tries to steer the game back toward a BDG by 2.Nc3 d5 3.e4, but Black sidetracks the effort into a Huebsch Gambit (3...Nxe4), which is one of those Blackmar-Diemer Gambit Avoided openings. White can avoid the Huebsch by 2.f3 d5 3.e4 dxe4 4.Nc3 (BDG). But Black can then avoid the BDG with 3...c5 or 3...e6 when White's 2.f3 is not that helpful. Now on to the game where Bill Chandler is using the handle: ProjectAlpha.

ProjectAlpha-ealps, ICC 5 0 Internet Chess Club, 01.01.2012 begins 1.d4 Nf6 2.Nc3 d5 3.e4 Nxe4 [This is the Huebsch Gambit. More common is 3...dxe4 4.f3 exf3 5.Nxf3 transposing to the BDG Accepted which we will see in tomorrow's post.] 4.Nxe4 dxe4 [Generally it is thought that trading the knights helps White more than Black, because the Nf6 is more useful for the kingside defence than the Nc3 for the planned kingside attack.] 5.Bf4 [White fights against an early ...e5. Historically White has usually chosen 5.Bc4.] 5...c6 6.f3 Bf5 7.Bc4 [Theoretically here the best move is probably 7.Qd2! with good compensation as I mentioned when I covered this line in my October 28, 2011 blog post.] 7...e6 8.fxe4 Bxe4 9.Nf3 Bd5 [The bishop is vulnerable here.] 10.Bd3 Nd7 11.0-0 h6? [Black wastes time to create a weakness. He should try 11...Qb6 =] 12.Ne5 Nxe5 13.Bxe5 Qb6 14.Qh5 [14.c4!+-] 14...0-0-0 15.Qxf7 [15.Rxf7! is better.] 15...Rd7 16.Qf2 Bd6 17.Bxd6 Rxd6 18.c3 g5 19.Qf6? [White has a little combination here with 19.c4!+- winning material.] 19...Qd8? [Black has 19...Qxb2! with the threat of 20.c4 Qxg2#] 20.Qxd8+ Rdxd8 21.a3 Rdf8 22.Rxf8+ Rxf8 23.Rf1 Rxf1+ 24.Kxf1 b5 25.g3 Kd7 26.Bg6 Kd6 27.Ke2 e5 28.Kd3 exd4 29.cxd4 c5 30.dxc5+ Kxc5 31.b4+ Kb6 32.Kd4 Bc4 33.Ke5 a5 34.Kf6 Be2 35.Kg7 h5 36.Kh6 h4 37.Kxg5 hxg3 38.hxg3 axb4 39.axb4 Kc6 40.Be4+ Kd6 41.Kf4 Ke6 42.g4? Kf6? [Black can save the game with 42...Bxg4! 43.Kxg4 Ke5 44.Bc6 Kd4 45.Bxb5 Kc3 winning the final pawn with a draw.] 43.g5+ Kg7 44.g6 Kf6 45.Bc2 Bc4 46.Ke4 Kg7 47.Ke5 Bf1 48.Kd6 Bc4 49.Kc5 Bf1 50.Be4 Be2 51.Bc6 Kxg6 52.Bxb5 Bf3 53.Bc6? [53.Kd6!+- and there is no helps for ealps.] 53...Be2 54.Bd5 Kf6 55.Bc4 Bf3? [55...Bh5! 56.Kd6 Be8 and the forced win disappears.] 56.b5 [56.Kd6!+- with an easier forced win.] 56...Ba8? 57.Bd5 Bxd5 58.Kxd5 Ke7 59.Kc6 Kd8 60.Kb7 Kd7 61.b6 Black forfeits on time 1-0

Blackmar-Diemer Easy Ryder into 2012

Happy New Year 2012!! Time for a new approach. My wife suggested I add to my blog other games such as those sent to me by those who read my blog. Jocelyn Bond sent me a game recently played vs xorigueres. This game reaches by transposition the BDG Accepted after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Qxf3. This is known as the Ryder Gambit, so named for the player of the earliest known game in the BDG.

Diemer considered only the Ryder Gambit (5.Qxf3) in his 1957 book entitled (in German) From the First Move Until Mate! He intended a second volume on recapturing with the knight (5.Nxf3 which he played much more often starting in the 1950s), but he never wrote the second book. In his 1957 book Diemer analyzed 75 Ryder Gambit games played from the 1930s-1950s. Some players still prefer the Ryder today.

Capturing with the queen allows tactical threats up the f-file and along the long diagonal, as well as leading to rapid queenside castling. The Ryder contains many traps offering quick wins, and is a strong temptation for any gambit player.

There are three chief drawbacks to the BDG Ryder (5.Qxf3):
1. Black can win an additional gambit pawn (5...Qxd4);
2. The queen on f3 hinders her own kingside development.
3. Black easily harasses the queen on f3.

None of that happens in the game below. The French Canadian player Jocelyn Bond wins a crisp 3 minute blitz game using the BDG Ryder Gambit. The opponents castle opposite sides. Black thinks his king is safe. Bond shows an eagle tactical eye for the thematic sacrifice 14.Bxh7+! Suddenly Black's king is the victim of a successful king hunt.

The notes below are those by Bond and faithful companion Fritz.

Bond-xorigueres (1947), Chess.com, 29.12.2011 begins 1.d4 Nf6 2.f3 d5 3.e4 dxe4 4.Nc3 exf3 5.Qxf3 e6 [5...a6!? 6.Nge2 Nc6-/+] 6.Bf4 Bb4 [6...Qxd4 7.Nb5 Qxb2 8.Nxc7+ Kd8 9.Rd1+ Bd7 10.Nxa8+/=] 7.Be5 [7.0-0-0 0-0=/+] 7...0-0 8.0-0-0 Nc6 9.Nh3 Bxc3 10.Qxc3 Nxe5 11.dxe5 Nd5 12.Qg3 Qe7 13.Bd3 c5?? [13...h6=/+ better resistance.] 14.Bxh7+! Kxh7 15.Ng5+ Kh6 [15...Kg8 16.Qh4 Qxg5+ 17.Qxg5 Bd7+-] 16.Qh4+ Kg6 17.Qh7+ Kxg5 18.Qxg7+ Kf5 19.Rhf1+ Ke4 [19...Nf4 20.g3 Qh4 21.gxh4 Rg8 22.Qxf7+ Kg4 23.Rxf4+ Kh3 24.Qxg8 Kxh2 25.h5 Bd7 26.Rh4#] 20.Qg4+ Kxe5 21.Qg3+ Ke4 22.Rde1+ [22.Rfe1+ Kf5 23.Re5+ Kf6 24.Qg5#] 22...Kd4 [22...Ne3 23.c4 Qg5 24.Qxg5 Kd3 25.Qf4 Nxf1 26.Qe4#] 23.Qd3# 1-0
