I don't think that 16. b4 is better than 16. Be3 because it allows Black to open up the position with a pawn advance a5 and opening up the position certainly will favor the two bishops which Black possesses. The real weakness in this position is Black backward d pawn, and once again like the game between Fritz 5.32 and CM 6000, Hiarcs 7 makes the same strategical mistake, the failure to exploit the backward pawn. It is a good idea to look at the game mentioned above, and you will notice that the strategy used to win the game by Black is similar in both games. In both accounts White fails to blockade, restrain and destroy the backward d pawn, in which both cases, Black was able to advance forward and gain space and central advantage. This is where both Fritz and Hiarcs faultered in their games. I believe that the mistake in Hiarcs game was move 21. Nh2? This is where Hiarcs faultered. It should have played 21. Bg5, with the idea of trading of the only piece which is able to defend the backward pawn. True, this violates a chess principle of trading off your good bishop (White's dark square bishop) for a bad bishop (Black's dark squared bishop). However, one will notice that the removal of this piece makes the d pawn very vulnerable. Remove the dark squared bishops from both sides and take a look at the position. What would be a good plan for White? How about doubling the Rooks on the half open d-file, and placing a White knight on the f5 square. Okay, White has a misplaced piece, the knight on a4, so what? Can Black use his piece advantage? This is only a temporary disadvantage, notice that once the d-pawn is destroyed, the c5 square becomes available for the White knight. Thus, I think that 21. Bg5 was the better move. Play could go as follows, 21. Bg5 Bxg5 22. Nxg5 Rf6 23. Qe3 with the idea of maneuvering the knight to f5, followed by f3 to strengthen the e4 square, and the doubling of the rooks on the d-file. Or 21. Bg5 Nf6 22 Bxf6 Rxf6 23. Nh4, with the same plan as mentioned before. In both cases White can claim full equality, and Black pieces are tied to defend the backward pawn.
