Below my commented game, a typical one to demonstrate the way humans may not
play vs a strong computer.

1. e4 c5 2. Nc3 Nc6 3. Bb5 Nd4 4. Bc4 e6 5. Nf3 Nf6 6. O-O a6 7. Re1 {
In my opinion an important inaccuracy. It was necessary to prevent b7-b5 with
7.a4} 7... b5 8. Bf1 Bb7 9. d3 d5 10. exd5 Nxd5 {Black stands already slightly
better: more active pieces and prospects for a kingside attack.} 11. Ne4 {
That's a wrong decision in my opinion. White's pieces have no perspectives and
Black's d5-knight has a dominating place in the centre. Therefore the exchange
11.Nxd5 seems the only logical try for me.} 11... Be7 12. c3 {This weakens the
d3-pawn and such a move should in principle be avoided at all cost. On the
other hand, it is hard for White to find a good plan and to drive away the
strong placed knight looks natural. We have a situation here that White should
not have allowed to arrive at against a computer. It's very uncomfortable to
have the worse position after only 12 moves.} 12... Nxf3+ 13. Qxf3 O-O 14. Bd2
Qd7 15. Qg3 {Threatening Bd2-h6} 15... f5 16. Ng5 Rf6 17. Nf3 Bd6 18. Ne5 Qc7
19. f4 Rd8 {White has done his best but it's not enough. The situation is
still the same. White can do nothing concrete and must wait what the opponent
will do. It seldom happens that such positions can be held vs a strong
computer program.} 20. Rad1 Rh6 21. b3 {This only weakens the position further.
It was time to make waiting moves like Kg1-h1-g1 or Bd2-c1-d1 and just to see
if Black would find a plan to improve its position.} 21... Nf6 22. h3 {
Such moves - if not forced - are strictly forbidden vs computers as this one
only weakens White on its dark squares.} 22... Nd7 23. c4 {White plays a
desperate style: look at the backward d3-pawn and the hole at d4. Better was
of course 23.Qf2 and to follow a do nothing but it well strategy.} 23... Be7
24. Nf3 Rg6 25. Qf2 Bd6 26. Nh4 {I would have 26.Ng5 given a trial with the
idea to attack e6 and to hope that Black will play h7-h6 when the rook would
no longer have the square h6.} 26... Rh6 27. Qg3 Rf8 28. Bc3 Rff6 {
A nice maneouvre probably overlooked by the human player.} 29. Be5 Nxe5 30.
fxe5 Be7 31. Re2 Rf8 32. Nf3 f4 33. Qf2 Rg6 {White is completely outplayed and
I can't see how it should be possible to save the game.} 34. cxb5 Rg3 {
Threatens Bxf3} 35. Re4 {Desperation, but it does not help} 35... axb5 36. Rxf4
Bxf3 37. Rxf8+ Kxf8 38. Rc1 Bh4 39. Qxc5+ Qxc5+ 40. Rxc5 Bd5 0-1
