Charles Bagby Memorial Tournament Report

by Abel Talamantez

The 20th Charles Bagby Memorial had a full house of chess enthusiasts with 77 players participating in this one-day G/45;d5 USCF rated event. This tournament is held in honor of former Mechanics' Institute Trustee and Chair of the Chess Committee at the Mechanics' Institute. Here is an obituary from the California Chess Reporter, courtesy of Chess Dryad.

Split into two sections, the 1800+ was a wide open field, especially after top seed IM Elliott Winslow was upset in round 1 by Mikhail Molodyk. After three rounds, Nicholas Weng was in position to take clear first as the only player with 3/3 after a terrific win against Evan Ai. However, NM Siddharth Arun held on to a draw against Weng in round 4 to create a 3-way tie for 1st place between Matthew Ng and Luiz Uribe, who all finished 3.5/4.

In the under 1800 section, recent UC Berkeley grad Adam Stafford continues his sharp rise with another tournament win, sharing first place with Daniil Kardava with a perfect 4/4. Stafford won his section at the recent Addison Memorial as well. We had 44 players in this section, and it was exciting to see many new faces jumping into live tournament play.

It was a great day at the Mechanics' Institute, as the excitement and energy were definitely in the room for live chess. There were many talented young players participating, some of whom will be the next generation of Bay Area stars. We also had many new players, and our always faithful Mechanics' Institute regulars. I would like to thank my two volunteer TD's, Chief TD WCM Allyson Wong and Michael Hsu, for helping me keep an eye on the games and making sure everything ran smoothly. I would also like to thank Allyson's mom Alice Lu for the irresitable (too much so) doughnuts.

Here are the final standings for the 20th Charles Bagby Memorial

Tuesday Night Marathon Round 2 Report

Round 2 of the TNM finished leaving the top section completely up for grabs as seven players are at the top with 1.5/2. Abhinav Penagalapati drew with IM Elliott Winslow on board 1 and Christophe Bambou drew with NM Siddharth Arun. After receiving a half point bye for round 1, Nicholas Weng won in a tough game against Chelsea Zhou when she flagged in what lookd like a drawn endgame. With 5 rounds to go, the top section is still wide open for anyone to make a move towards the top.

The top four boards do battle, including Abhinav Pebagalapati from the San Jose Chess Club against IM Elliott Winslow

In the under 2000 section, some rising young stars and a veteran Mechanics' player occupy the top four spots in the standings with 2/2. Leon Quin, Adam Stafford and Kevin Sun won their games and are 2/2 representing youth, while veteran Albert Starr got a point by virtue of a no-show. Kevin used a great tactical shot to defeat Marty Cortinas, showing that the kid is definitely studying his tactics. 

In the under 1600 section, Dominic Zirbel, Sebby Suarez, David Nichol, and Isaac Sterling are all perfect with 2/2.

White has an aggressive attacking position with the two bishops and advanced kingside pawns. 19...Nc6 20.Bxe4 [20.f6!] 20...Qc7 21.Qg2 Rb8 22.0-0?! [22.0-0-0!] 22...Nd4 23.f6 Re6 24.fxg7 Bxe4 25.Qxe4 Qxc2 26.Qxc2?! [26.Qg4] 26...Nxc2 27.Ba7 Nxa1 28.Bxb8 Nxb8 29.Rxa1 Kxg7

12...Bg4? [12...Ng4! all but forces a draw at least, but maybe Ako wanted more. 13.cxd5 Nxh2! 14.Kxh2 Qh4+ 15.Kg1 Bd6 went it's a perpetual after either pawn move 16.f4 (16.g3 Bxg3=) 16...exf3 17.Rxf3 Qh2+ 18.Kf2 Qh4+ 19.Kf1 (19.Kg1; 19.g3?? Qh2+ 20.Ke1 Bg4-+) ] 13.Bb2+/- Rc8?

Stockfish's three top moves are bishop retreats! 14.Rfd1?! [14.Nxe4! works nicely!] 14...Qd7 15.Bxg4 Qxg4 16.Ne2! It mght look like Black is okay, but White gets to the key squares quickly. 16...Rfd8 17.Rac1 h5?! 18.Bxf6 gxf6 19.h3! An important escape for the king 19...Qg5?! 20.cxd5 Rxd5 [20...cxd5 21.Qxc8 Rxc8 22.Rxc8+ Kg7 23.Nf4 is too much for Black to survive.] 21.Qxe4 Sadly Black's pawn structure is shattered.

[de Firmian]

1.d4 f5 2.Nf3 Nf6 3.c4 g6 4.Nc3 Bg7 5.Bf4 An unusual but reasonable move. It has themes from the London System. 5...0-0 6.e3 d6 7.Be2 Be6?! This is certainly provacative. 7...c6 would be safer. 8.Ng5 Bd7

9.h4 A good positional move, but [9.c5! Kh8 (9...h6 10.Qb3+ d5 11.Nxd5) 10.Qb3 would win at least a pawn for White] 9...h6 10.Nf3 Be8 11.Qb3 b6 12.d5 Nbd7 13.Nd4 Nc5 14.Qc2 a5 White has the edge with the strong knight on d4 and the soft black light squares on e6 and c6. 15.f3 Bf7 16.0-0-0!? Abel plays aggressivley! The game is heating up. 16...e5 17.dxe6 Nxe6 18.g4! A fine move, not worrying about the doubled f-pawns that arise. 18...Nxf4 19.exf4 Qc8?! [19...fxg4 20.fxg4 Qd7 21.Rhg1 is very good for White but material stays equal] 20.gxf5 c5! 21.fxg6! cxd4 22.gxf7+ Rxf7 23.Rxd4 Ne8 24.Re4 Nc7 25.Rg1

With the two extra pawns and safer king White is winning. Albert makes it a fight though. 25...Kh8 26.Bd3 Ne6 27.Nb5?! [27.Nd5] 27...Qc5! 28.Rge1 [28.Rg6 Nxf4 29.Nxd6!] 28...Nxf4 29.Re8+ Rxe8 30.Rxe8+ Rf8 31.Re1?! [31.Rxf8+ Bxf8 32.Qd2 would keep a big edge] 31...Nxd3+ 32.Qxd3 Qf2 [32...Bxb2+!] 33.Re2 Qf1+ 34.Kc2 Be5 35.Qd2 Rf6 36.Rxe5?

A bit of a panic move to force the issue. White is still fine after [36.Nc3] 36...Qxc4+! The zwischenzug crosses White up. Now Black gets a clear edge. 37.Kb1?! [37.Nc3] 37...dxe5 38.Qd8+ Kg7 39.Qe7+ Qf7 40.Qxe5 Qg6+ 41.Kc1 Qg1+ 42.Kd2 Qf2+ Nice technique by Albert.

1.Nf3 f5 2.d4 Nf6 3.c4 e6 4.Nc3 Bb4 5.Bd2

Does this have a name? Some combination of Nimzo and Bogo followed by Dutch seems like it gets there. 5...Bxc3 6.Bxc3 Ne4 7.Qc2 0-0 8.g3 Nxc3?! There should be no rush to trade off the strong knight right away. 9.Qxc3 b6 10.Bg2 Bb7 11.0-0 d6 12.Rfd1 Qf6 13.Rac1 a5?!

Weakening the queenside. [13...Nd7 Development was called for.] 14.c5! In an otherwise quiet game so far, White opens lines to capitalize on his better development. 14...Na6 [14...dxc5 15.dxc5 Qxc3 16.Rxc3] 15.cxb6 cxb6 16.Qb3?! [16.a3! first stops Black from an interim defense of b6.] 16...Nb4! Back to the center. Now Black is close to equality. 17.Nd2 Bxg2 18.Kxg2 Qe7 [18...f4! peeks into White's kingside and leaves White with no advantage.] 19.Nc4 Rab8 20.a3 Na6?! [20...Nd5 21.Ne3! is better, but not by much.] 21.Kg1?! White had more useful things to do. 21...Nc7 22.Nd2 And here: [22.Rc2; 22.Qf3] 22...f4 23.Rc6 Nd5 24.Ne4 Rbd8

25.Nc3? [25.Qd3 keeps the advantage.] 25...fxg3 26.hxg3 Nf4? Black sees a mirage -- [26...Qf7 27.f3 Ne3-/+] 27.gxf4 Rxf4 28.Rd3 -- and is lost. [28.f3!] 28...Rdf8 29.Nd1 Qf7 30.Rf3 This really dampens the attack. 30...Qg6+ 31.Rg3 Qe4 32.Qc2 Qxc2 33.Rxc2 Rxd4 34.Ne3 b5 35.Rc7 Rf7 36.Rc8+ Rf8 37.Rc2 h5 38.Rg5 Rdf4 39.Rc7 R8f7 40.Rxf7 Kxf7 41.Rxb5 d5 42.Rxa5 g5

43.Nxd5 Not necessary, and objectively giving away some of his advantage, but the simplification should convince Black to resign. 43...exd5 44.Rxd5 Kf6 45.Rd3 g4 46.Rd5 Kg6 47.b4 Rc4 48.Rc5 Rd4 49.b5 Rd2 50.e3 h4 51.b6 Rb2 52.Rc6+ Kf5 53.a4 Ke4 54.Rc4+ Kf5 55.Rf4+ Kg5 56.a5 h3 57.Kh2 Kh4 58.e4 Rxf2+!
