Apr-16-06  savitri1232001: what a game played between veselin topalov and krishnan sasikiran this is a very fantastic game played by sasikiran against topalov with king's Indian defense just a brilliant game
Apr-16-06  AlexanderMorphy: well i just hve a feeling Topalov wanted the draw and wasn't aiming for a win here...not sure how the standings were at the ime in the olympiad...but it looks as though he was looking to exchange pieces fast and draw...
May-13-07  argishti: He could have won this.

May-19-09  furrer: isnt the game won around move 63 according to the troitzky line rule?
May-19-09  shalgo: According to the tablebase at, the position at move 63 (and thereafter) is a draw.
Feb-02-12  Whitehat1963: I thought K+N+N v. K was insufficient material to mate.

  alexmagnus: there are mate-in-1 positions with KNN vs K. But to my knowledge it is impossible to construct a position with this material which are mate in 2 or more with perfect play - so, all you have to look after is not running into a 1-move mate :)
Feb-02-12  Whitehat1963: <alexmagnus>, surely a player of Sasikiran's abilities would know that. Was this done out of spite or hatred, perhaps? I mean, the last 20 moves or so must have bored and annoyed them both.
May-27-14  GrandMaesterPycelle: The pawn at move 63 falls within the Troitzky lines, but the endgame is a draw because it needs to be blocked with one of the knights to play for the win. So that once the king is somehow confined, it can hop over and deliver mate. Once the king moves & Topalov pushes h6 before the knight can block, it's immediately a draw, because the pawn is now out of the Troitzky lines.

Exactly! There are basically two checkmate positions with KNN vs K:

but a tiny bit of retroanalysis shows that in both cases the king had an alternative to moving into checkmate on his last move. Hence there are no mating nets in this endgame, and consequently the knights cannot win except for the trivial case of mate-in-one.

(I vaguely remember something about the 2N-mate being possible if there were additional squares d9 and e9 on the board, but this of course belongs to the fairy chess department.)
