Games versus GMs

Welcome to my chess page. This is mostly random thoughts and analysis in the form of a chess diary with other sections of the site slowly developing. A lot of the content will come from my own experience. There are two reasons for this. One, so I can use this site as a self-improvement tool. Two, so you the readers will have content that is not found on other chess sites. Follow the link to the left to reach my annotated games against grandmasters. Send me comments and ideas

Corrections to Basic Chess Endings

8/13/18 - Bereolos-Bisguier, 1989 US Open

The other time I faced GM Bisguier was in the 1989 US Open. This was a somewhat dull game, but it was still memorable for me as it was my first draw against a GM. Regarding my comment at the end that Ulf Andersson would have played on, I give you the game Andersson-Milov from the 1997 FIDE KO tournament. 1.d4 Nf6 2.Nf3 d5 3.c4 e6 4.g3 dxc4 5.Qa4+ Nbd7 6.Bg2 a6 7.Nc3 Rb8 8.Qxc4 b5 9.Qd3 Bb7 10.0-0 c5 11.dxc5 Bxc5 12.Bf4 Rc8 13.Rad1 b4 14.Na4 Be7 15.Ne5 Bxg2 16.Kxg2 Qa5 17.Nxd7 Qxa4 18.Nxf6+ Bxf6 19.b3 Qc6+ 20.Qf3 Qxf3+ 21.Kxf3

The same material and a similar pawn structure to the variation at the end of Bereolos-Bisguier 21...Rc3+ 22.Kg2 a5 23.Rd6 g5 24.Be3 a4 25.bxa4 0-0 26.a5 Ra8 27.a6 Ra3 28.a7 Rxa2 29.Rd7 Kg7 30.Rb7 Rxe2 31.Rd1 b3 32.Rb8 1-0

8/10/18 - Raghavan-Bereolos, 2018 National Senior Tournament of Champions

My only loss in the event was to Vijay Raghavan from the host state of Wisconsin. He thoroughly outprepared me in the opening reaching a small endgame advantage through move 22, while I was on my own after only 11 moves. I finally bailed out to what should have been a drawn rook ending a pawn down. I proceeded to completely butcher it with a series of substandard moves, and found myself in a lost position after 43...Rxh4

44.Ra8+ Ke7 45.Rxa5 Rh2 46.Rg5 A small ray of hope. I expected 46.g4 h4 47.f4 which should be relatively easy for White 46...h4 47.Kg7? White still had a path to the win here with 47.f4 h3 48.g4! Rg2 49.Kf5! h2 50.Rh5 Kf7 51.g5 Kg7 52.Rh6 and White will be able to collect the h-pawn by walking his king walk back to g3 via g4 or e4 47...h3! 48.gxh3 Rxh3! 49.Re5+ Kd6! 50.f4 At this point I felt that I should be able to draw, but I did not find the correct technique 50...Rf3! 51.Rf5 Ke6 52.Kg6

52...Ke7? 52...Rg3+! 53.Rg5! Re3! preventing Re5+ 54.f5+ Ke7! 55.Kg7 (55.Rg1 Kf8) 55...Rf3! and White can't make progress He gave me no further chances 53.Rf7+! Ke6 54.f5+ Ke5 55.Re7+ Kf4 56.f6 Rg3+ 57.Kf7 Kg5 58.Re8 Rf3 to prevent Kg7 59.Rg8+ Kh6 60.Rg6+ Kh7 The king made it around to the short side, but the rook needs to be on a square like a3 in order to give checks from the side. 61.Rg2 Kh6 62.Rh2+ Kg5 63.Kg7 1-0

Lessons from this ending. 1. Don't get discouraged. There will be plenty of time after the game to kick yourself over bad moves. As long as the game is going you have to be ready if your opponent presents you with an opportunity. 2. Keep studying the endgame, there is always more to learn. I had never seen the drawing method with the king on the long side of the pawn before.

8/8/18 - BCE-365/Spielmann-Alekhine, New York 1927

Position 365 shows the power of an active king in a 2 vs. 1 rook ending with no passed pawns. This example comes from the the elite New York 1927 tournament, which was the last big showdown between Capablance and Alekhine before their World Championship match. The leadup to the BCE position is instructive as well.

The slightly odd position of the Black rook is explained by the fact that he just captured a pawn on h6. This position doesn't look like it should hold much danger to White, but watch how quickly Spielmann collapsed. 60. Ke3 Kg4 61. Re4+ In Alekhine's tournament book he suggests 61. Ke2 Rh1 62. Re4+ Kf5 3. Ra4 with equality. Black could still try 62...Kh3 as in the game, but with the Black rook on h1, White can even play 63. Rf4 f5 64. Ra4 followed by counterattack against the Black pawns after 64...Kg2 65. Ra6! g5 66. Rf6 f4 67. Rf5! Rh5 68. Ra5 and White is holding 62...Kh3 63. Rf4? Reaching the BCE-365 position. In addition to the active Black king, the White rook finds itself on an awkward square. Alekhine points out that White could still have drawn with 63. Ke2. The game didn't last much longer 63...f5! 64. Rf3+ Kh2! 64...Kg2? allows White to tie the Black rook to g6 with 65. Rg3+! 64. Rf4 Now, 64. Rg3 is met by 64...Rh3! with a winning pawn ending. 64...Rh3+ 0-1The f-pawn is falling for example 65. f3 Kg2 66. Ke2 Rh8 67. Ke3 Re7+ 68. Kd2 Kg3 or 65. Ke2 Kg2 when 66. f3 transposes to the previous note and other moves are met by 66...Rf3

The defense via perpetual check in the BCE correction should also help the reader to solve the following Black to play and draw exercise from Aagaard's Endgame Play

8/4/16 - Bereolos-Perez, 2018 National Tournament of Senior Champions

I was at the US Open site last weekend to take place in the first ever National Tournament of Senior Champions. I'm providing the following annotated game for the Tennessee state newsletter, so I thought I'd share it here as well.

I had the privilege of representing Tennessee in the inaugural National Tournament of Senior Champions. This is the 3rd invitational tournament that has been modeled after the Denker Tournament of High School Champions following the Barber Tournament of K-8 Champions and the National Girls Tournament of Champions. It was a pretty strong field with 4 grandmasters (Fishbein, Zapata, Rohde, and Sevillano). I was seeded 6th out of 42 players and ended up tied for 6-9th. My best effort was in the final round with White against the Washington state representative FM Ignacio Perez. 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f4 0-0 6.Nf3 c5 7.d5 b5 8.cxb5 a6 9.a4

There is an interesting anecdote associated with this position. The 2017 South Carolina Senior Open served as their qualifier for this tournament for the highest scoring resident. Going into the last round, I led South Carolina's Klaus Pohl by half a point. Before the round Klaus was furiously calculating tiebreakers and then told me that if we drew then he would be guaranteed to be the SC representative, while I would take clear first in the tournament. So after playing 9. a4, I offered a draw, expecting an early trip back to Knoxville. Instead, Klaus' fighting spirit took over and he declined! I wasn't too upset by this as I have a huge score from the diagram position (+9 =1 -1) and went on to win a nice game. Things still worked out for Klaus as Daniel Quigley was unable to attend the Tournament of Champions and Klaus got to represent South Carolina after all. 9...e6 Klaus continued with 9...Qa5 10.Be2 The other main line here is 10.dxe6 which I used successfully against Justin Daniel in the 2000 Land of the Sky tournament. 10...axb5 11.Bxb5 White has lost a tempo with Be2xb5, but Black has some issues with his development as well. In particular, he needs to find a good square for Nb8. In the game, this was a problem he did not manage to overcome. 11...exd5 12.e5 dxe5 Theory considers 12...Ne8 the best way to equalize, but White won the only game I found with this in the database. 13.fxe5 Ne4 This move surprised me. I expected 13...Ng4 which allows Black to recover the e5 pawn more quickly than in the game although White still retains some pull. 14.Qxd5 Nxc3 15.Qxd8 15.Qxa8?! Qd1+ 16.Kf2 Qc2+ looked too dangerous to me, but the engine says Black doesn't have more than perpetual check. Afterwards, we also looked at the line 16...Qxh1 17.bxc3 Bg4 18.Bb2 Bxf3 19.Qxf3 Qxh2 and concluded Black was in trouble because of the passed a-pawn after 20.a5 15...Rxd8 16.bxc3 Bd7 We spent alot of time in the post mortem looking at alternatives here. We concluded 16...h6 stopping Bg5 was likely the best try, but such a non-developing move isn't going to bother White too much and he is still pressing after 17.Be3 17.Bg5 Re8 18.0-0 Bxe5 19.Nxe5 Rxe5 20.Bf6 I decided on this move because it boxed in the Black king. The other move I considered was 20.Bf4 which has the advantage of targeting Nb8. White also has a big edge here, for example 20...Re8 21.Rad1 Bxb5 22.axb5 Ra7 23.b6 Rb7 24.Bc7 and Black is quite tied up. 20...Bxb5 This loses by force. Also bad is 20...Rf5 21.Rxf5 Bxf5 22.Rd1 and Nb8 is completely dominated; Probably the best Black can do is something like 20...Re4 21.Rad1 Ra7 22.Rd6 (22.Rfe1 to trade the active rook is also good.) 22...Bxb5 23.axb5 Nd7 24.b6 Rb7 25.Bd8 and Black still has problems to solve 21.axb5 Rxa1

22.Bxe5 White should also win the rook ending after 22.Rxa1 Re6 23.Ra8 Rxf6 24.Rxb8+ Kg7 25.Rc8 but I was able to calculate the B vs. N ending all the way to a win. 22...Rxf1+ 23.Kxf1 Nd7 The knight finally leaves home, but it is much too late 24.Bc7 c4 25.b6 Nc5 26.Ke2 Nb7 26...Kf8 27.Bd6+ was the point of forcing the knight to c5. 27.Ke3 Kf8 28.Kd4 Na5 28...Ke7 29.Kxc4 Ke6 30.Kb5 Kd5 31.c4+ Kd4 32.Bg3 f5 33.c5 is no better 29.Kc5 Ke7 30.Kb5 Nb7 31.Ka6 31.Kxc4 would transpose to the note after Black's 28th move. 31...Nc5+ 32.Ka7 Ke6 33.b7 Nxb7 34.Kxb7 Kd5 35.Kb6 f5 36.Kb5 g5 37.g3 h5 38.h4 Black resigned, the ending is easily won for White, for example 38...gxh4 39.gxh4 Ke4 40.Kxc4 f4 41.Bb8 f3 42.Bg3; 38...f4 39.gxf4 gxh4 40.f5 h3 41.Bh2 h4 42.Kb4 1-0

I'd like to thank the US Chess Senior committee, especially David Grimaud, for getting this tournament off the ground. The Denker started the year after I graduated high school, so I never had the opportunity to play in that event. The tournament was smoothly run by John Haskell with no incidents. All rounds started on time and were well spaced so that you could analyze with your opponent and still get a decent meal between rounds. That's something all tournaments shoudl strive for. Also, thanks to the ICC, which provided memberships to all participants in all 4 invitational tournaments. Finally, thanks to the TCA which provided a small travel stipend which helped offset some of my expenses. Congratulations to GM Alex Fishbein, who was the winner of the event on tiebreaks. He adds this victory to his win in the inaugural Denker event.

8/1/18 - BCE-297c

Another short one this week. In the battle of rook versus 3 far advanced connected passed pawns, White still manages to draw thanks to some stalemate tricks.
