Notes from the Class E Underground That was the title Pat Barron gave to the collection of his games from the Pittsburgh Open that he sent to me. I have selected two of the five, which were relatively more challenge and complexity than the others. White: Patrick Barron Black: Darrin Bond Pittsburgh Open, June 1998 Sicilian Defense 1 e4 c5 2 Nf3 d6 3 Nc3 e6 4 Bb5+ Bd7 5 O-O a6 6 Bxd7+ Qxd7 7 d3 Nc6 8 Be3 Be7 9 d4 cxd4 10 Bxd4 Nf6 11 Bxf6 White's last two moves make a strange impression, as if he were convinced that knights are better than bishops and determined to exchange a bishop for a knight. But objectively, he isn't getting an advantage, and might have done better with a more conventional plan, such as playing 7 d4, or even 4 d4. 11 ... Bxf6 12 Re1 Black might now play 12 ... Bxc3, so that after 13 bxc3 he could attack the isolated doubled pawns on the c-file. His own queen pawn would be vulnerable, but after suitable preparation he could advance it to d5 and exchange it, and I do not see an effective answer to this plan. 12 ... O-O This allows a tactic. Instead, 12 ... Qc7 first give White more to think about. 13 e5! Be7 14 exd6 Otherwise Black plays 14 ... d5. 14 ... Bxd6 14 ... Qxd6 might be simpler. 15 Ne4 Rad8 16 Qd2 Ne5 17 Rad1 Nc4 17 ... Nxf3+ 18 gxf3 would leave Black with no way to defend or retreat his bishop! It appears that Black's position is precarious, but he has a way out. 18 Qd4 Qc6 19 Nxd6 The critical test is 19 b3. If Black retreats the knight he loses a piece, so instead 19 ... Bxh2+ 20 Kxh2 Rxd4 wins the queen. And after 21 Nxd4 Qc7 is check, so Black will have time to save his knight. 19 ... Rxd6 20 Qc3 Rfd8 21 Rxd6 Rxd6 White must now play alertly, because after queens are traded, Black's rook and knight are well placed to take the initiative, while White's rook and knight will be doing relatively little. 22 b3! Nd2 22 ... Nb6 23 Qxc6 Rxc6 24 c4 leaves Black with nothing. 23 Qxc6 bxc6 White should now take the bull by the horns with 24 Nxd2 Rxd2 25 Rc1. He is then ready to break out of the bind by 26 Kf1 and 27 Ke1; the only tricky line is 25 ... e5 26 Kf1 e4 27 Ke1 e3, but White then has 28 Rd1! forcing 28 ... Rxd1+ 29 Kxd1 exf2 30 Ke2, with an endgame that looks hard to evaluate. Another plausible defense is 24 Ne5. Black may then get a slight initiative with 24 ... c5 and 25 ... c4, but maybe it's only a mirage. Even 24 Rc1 may be all right. After 24 ... Nxf3+ 25 gxf3, White has ugly doubled pawns, but he will be able to force the trade of rooks, after which his queenside majority will hold the game. Other moves are less convincing. For instance, 24 Ng5 h6 25 Nh3 Ne4! followed by ... Nc3 and ... Rd2 looks hard for White to defend. 24 Rd1?? Nxf3+ 25 gxf3 Rxd1+ and Black won easily. White: Jeffrey Surma Black: Patrick Barron Pittsburgh Open, June 1998 Ruy Lopez 1 e4 e5 2 Nf3 Nc6 3 Bb5 Nf6 4 Bxc6 A dogmatic move, hinting that the player of White prefers knights over bishops. 4 ... bxc6 5 d3 Bd6 This is an awkward way to defend the pawn. Black has nothing to fear from 5 ... d6, which is much more natural and flexible. 6 O-O O-O 7 Re1 Qe7 8 h3 Bc5 9 c3 d5 10 Bg5 Both players are apparently unaware that Black would lose his king pawn after 10 exd5. 10 ... h6 11 Bxf6 Qxf6 12 d4 exd4 13 cxd4 dxe4 14 Rxe4 Bf5 15 Re5 Rad8? 16 Rxc5 A devastating blow. But Black does not lose hope! 16 ... Be4 17 Ne6 Qg5 18 f3 f6 19 Ng4? Qxc5 Of course, 19 fxe4 was correct. White now ends up with two pieces for the rook, but his disorganized and undeveloped position is soon overrun. 20 fxe4 Rxd4 21 Qf3 Rxe4+ 22 Kh2 Re1 23 Nf2 Rfe8 24 g3 R8e3 25 Qg2 R3e2 26 Nd3 Rxg2+ Pat writes, "I can't believe I missed 26 ... Qg1++!" 27 Kxg2 Qg1+ 28 Kf3 Rf1+ 29 Ke2 Qg2+ 30 Ke3 f5 31 Nf4 Qxg3+ 32 Ke2 Qxf4 Resigns
