Round 5 v South Korea, NZ lose 2.5-3.5

Scott's game was a real pity, he played beautiful chess and seemed to be converting a well earned extra pawn, but then a couple of inaccuracies saw a complete turn-around. John slowly improved his bad French bishop, his opponent accepted it was worth his previously better knight, so it was swapped off for a quiet draw. Emily got more than enough for her queen in a wild attacking game, and came very close to converting. Yolanda's opponent handled the White side of a Carlsbad QGD well and started collecting pawns. Allen basically overwhelmed his opponent but then liquidated to an endgame that required quite a lot of precision and a small slip meant a draw. Karen's opponent managed to open lines against Karen's Dutch and won a nice attacking game. Update: Actually Karen's opponent was disqualified by the fair play committee, presumably for computer assistance.

1.e4 c6 2.Nc3 d5 3.Nf3 Bg4 4.d4 A sideline, I suspect Scott preparation here. I will ask him and update this later  4...Nf6 5.h3 Now a sideline of a sideline  5...dxe4? I think White has tricked his opponent, this seems to be a novelty ( Bacrot (2715) - Ponomariov (2699), Biel SUI 2017, 1/2-1/2 in 44 moves 5...Bxf3 This has been played a few times  6.Qxf3 dxe4 7.Qe3 Nbd7 8.Nxe4 Nxe4 9.Qxe4 g6 10.Be2 Bg7 11.O-O O-O 12.Rd1 Re8 13.c3 Qc7 14.d5 c5 15.Bf4 Be5 16.Be3 Rac8 17.a4 Red8 18.a5 Nf6 19.Qf3 Kg7 20.a6 Rb8 21.axb7 Rxb7 22.Ra2 Rdb8 23.Bc1 Ne8 24.Qe3 Bf6 25.Ra6 Qe5 26.Qxe5 Bxe5 27.Ra5 Rxb2 28.Bxb2 Rxb2 29.Bd3 Bxc3 30.Rxc5 Bb4 31.Rc2 Rxc2 32.Bxc2 a5 33.f4 h5 34.Kf2 Kf6 35.Kf3 Nd6 36.Ba4 Nf5 37.Bd7 Nh4+ 38.Kf2 Bc5+ 39.Kf1 Nf5 40.Ke2 Bd6 41.Kf3 Nh4+ 42.Kf2 Bc5+ 43.Kf1 Nf5 44.Ke2 Bd6 ) 6.hxg4 exf3 7.gxf3 White's position might look a little odd, but the space and the two bishops mean he's better. In the next phase White continues to be push aggressively without worrying about creating possible weaknesses. I think aggressive pawn play is very characteristic of modern chess  7...e6 8.Be3 Bb4 9.a3 Ba5 10.b4 Bc7 11.g5 Nd5 12.Nxd5 cxd5 13.c4 dxc4 14.Bxc4 Nc6 15.d5 exd5 16.Qxd5 Qxd5 17.Bxd5 O-O 18.Rc1 Rfe8

19.Rxc6! Cashing in and heading for a stable pawn up ending  19...Rxe3+ 20.fxe3 bxc6 21.Bxc6 Rc8 22.Ke2 Bd8 23.Be4 Bxg5 24.Bxh7+ Kf8 25.Bd3 Rc3 26.a4 Ra3 27.Rh8+ Ke7 28.f4 Bf6 29.a5 Bc3 30.Rb8 Ra4 31.Rb7+ Kf6 32.Rxa7 Bxb4 33.a6 Ra2+ 34.Kf3 Ra3 35.Ke4 Ra4 36.Kd5 Ra5+ 37.Ke4 Ra4 38.Kf3 Ra3









 

39.Bc4! White is close to victory and understandably avoids repeating with Ke4. This is the best move even though it does allow a shot.  39...Rxe3+! 40.Kg4 (40.Kxe3 Bc5+ 41.Ke4 Bxa7 42.Kd5 Kf5 is of course a dead draw ) 40...Be7 41.Bd5? Up until here White has played brilliantly, but chess is a brutal game and a few inaccuracies turn out to be enough to turn the tide.  (41.Rc7! Gets out of the way and threatens Rc6+ winning the Bishop so Black has no time to react. The a-pawn will quickly cost Black his rook  ) 41...Ra3 42.Bc4 Ra4 43.Bd5? ( Even after granting Black the tempo to get back to the a-file 43.Rc7 still wins ) 43...g5!? Turning the tables to a certain extent  44.Kf3 ( Although curiously 44.Rc7! is still the right move as Black cannot play  44...Rxf4+ 45.Kh3!! and White wins. Instead Black should simply take the 'a' pawn and the game will presumably end in a draw ) 44...Rxf4+ 45.Ke2 Ra4 The win is gone but annoyingly Black starts playing as if he is better, which at least numerically he is  46.Bc6 Ra5 47.Be4 Bc5 Now Black has a7 firmly under control and the situation rapidly deteriorates  48.Ra8 Ke5 49.Bd3 g4 50.Rb8 Ra2+ 51.Ke1 Bf2+ 52.Kf1 Bc5 53.Re8+ Kd4 54.Be2 f5 55.Rg8 Ke3 56.Bxg4 Bailing out into a notoriously difficult (for both sides) ending. The rest of the game is even further above my pay grade. It is a theoretical win, I am sure Scott knows about the defensive systems that are very hard to break down, so congratulations to Black for converting.  56...fxg4 57.Rxg4 Rxa6 58.Rg8 Ra2 59.Rg3+ Ke4 60.Rg7 Be3 61.Re7+ Kf3 62.Rf7+ Bf4 63.Re7 Rh2 64.Rg7 Be5 65.Rf7+ Ke3 66.Re7 Kf4 67.Rf7+ Ke4 68.Re7 Ra2 69.Rf7 Bf4 70.Rf8 Be3 71.Re8+ Kd3 72.Rd8+ Bd4 73.Re8 Rf2+ 74.Ke1 Rg2 75.Rf8 Rg1+ 76.Rf1 Rg2 77.Rf3+ Be3 78.Rf1 Rc2 0-1

Total mayhem ensues from now until the end of the game. It pretty much defies analysis (or maybe I am just lazy) but it's great fun and worth playing through. Nine year old Emily shows great fighting spirit and spurns draws in search of victory.
