[Event "Piet Robbertse 2015 - Prestige Section"]  [Site "Hoërskool Waterkloof"]  [Date "2015.02.01"]  [Round "6"]  [White "Johannes Manyedi, Mabusela"]  [Black "Hercules, Benjamin Vincent"]  [Result "1-0"]  [BlackElo "2244"]  [ECO "A56"]  [Opening "Benoni"]  [Variation "Czech, 5.e4 Be7 6.Nf3 O-O 7.h3"]  [WhiteElo "2086"]  [PlyCount "43"]   1. d4 {[1:30:57]} Nf6 {[1:30:32]} 2. c4 {[1:31:16]} c5 {[1:30:38]Hercules  is ready to play some sharp lines. If you want fighting chess when playing  black against d4 the Benoni is certainly to be considered.} 3. d5  {[1:30:18]} e5 {[1:29:58] This move is interesting because it is likely to  completely change the character of the position. We were looking at the  possibility of very sharp lines but now the position is going to be closed  with a lot of manoveuring.} 4. Nc3 {[1:28:54]} d6 {[1:27:27]} 5. e4  {[1:28:55]} Be7 {[1:27:41]} 6. h3 {[1:29:17]} Nbd7 {[1:27:42] Black's  position is solid but a little cramped. It is much easier finding the moves  on the white side.} 7. Be3 {[1:28:03]} Nf8 {[1:25:42]} 8. Qd2 {[1:21:53]  White's setup also works against the King's Indian.} h5 {[1:23:59] So far  the players have been playing quite fast but this one seems to be the first  long think of the game.} 9. Bd3 {[1:02:04] White responds by also taking  time on his own move.} Ng6 {[1:17:33]} 10. Nf3 {[1:00:20] Interestingly my  computer evaluation is showing that it is now black who holds a slight  advantage.} h4 {[1:16:42] It looks like so far so good from Black.} 11. Ne2  {[0:58:32]} Bd7 {[1:15:06] It looks like both players are getting ready to  push their Queenside pawns} 12. b4 {[0:56:52]} b6 {[1:11:07] Black could  also have taken on b6 then followed up with Qc8 and b6 with a solid setup.}  13. bxc5 {[0:55:39]} bxc5 {[1:11:15]} 14. Rb1 {[0:56:03]} Qc8 {[1:10:42] Is  Black looking at putting pressure on the c8 -h3 diagonal. Perhaps the Queen  is better placed on c7.} 15. Qa5 {[0:43:25]} Bd8 {[1:03:44] Nh5 could also  have been played here.} 16. Qa3 {[0:43:49]} Rb8 {[1:03:40]} 17. Rxb8  {[0:40:55]} Qxb8 {[1:04:06]} 18. Bc2 {[0:41:12]} O-O {[1:03:47]} 19. O-O  {[0:40:52]} Qc7 {[1:03:37]} 20. Rb1 {[0:39:19]} Qc8 {[1:01:30]} 21. Kh2  {[0:38:25]} Nh5? {[0:58:59] A blunder! Black gives away the pawn on a7 and  the game. Better was Bb6 when white will struggle to break through on the  Queenside.} 22. Qxa7 {[0:37:57] Quite a puzzling game to analyse. The  computer evaluation was showing that Black was doing fine in the game if  not a little better. He was also ahead on the clock and everything ended  with one move. It looks like Black had the right ideas but maybe lost  concentration.} 1-0
