csmath: 6. ... g6?!
Attempt for original game, played by Smeets last year.
7. Qb3
Grunfeld-like response.
7. ... dxc4?!
in kind but probably a positional error, black is already slow in development on the queenside.
After 10 moves, black position is passive and his pieces lack development. Simply a bad opening.
11.e5!
Further restraining both of black bishops and slowing down development of the black queenside.
15. ... Rd7?!
Kramnik keeps on playing passive waiting moves.
16. ... c5!
Finally but it might be a little late since white pieces are now optimally active.
20. ... Bxe4?
Unfortunate decision.
[It seems better would have been to play 20. ... c4! with white maintaining advantage but with 21. Bxb7 Qxb7 22. Rxd8 Rxd8 23. Qxc4 Rd5 leading into difficult but perhaps defensible ending.]
24. d7!
This is decisive move.
25. ... c4?!
[Outright losing move, now it is too late. Unfortunately there is nothing better: 25. ... Rd8
26. Qc7 Nxb2
27. Rb1 Nc4
28. Nxc5 Nb6
29. Rd1 Nd5
30. Rxd5! exd5
31. Nb7 Bf6
32. Nxd8 Bxd8
33. Qe5
and black is in lost position]
26. ... Rd8?!
This is even worse but the game is already lost.
Few more moves with Kramnik attempting to get cheap smothered mate that Andreikin routinely repells and then Kramnik resigns ahead of being checkmated himself.
