checkmate with 2 knights?

  • #21

    K+2 Kts vs K = DRAW with correct play by the defender. All the Kts can do is stalemate the lone King. BUT, with a K+P after the King is stalemated the pawn moves while the Kts get repositioned for checkmate. The longest such mate requires 66 moves and in 1992 FIDE abolished all exceptions to the 50 move rule because no one knows any of them including most GMs, at least according to me - and at least one GM named Karpov.

    As Botvinnik said in this book, Lilienthal had gotten that endgame 3 times in his career already by that point...and was unable to win it any of those times...

    Nimzovitch erroneously traded down into this ending with a K+RP, which loses even if it's on the 6th-rank, but Nimzo didn't know this back in 1913 (I wonder if anyone else did)

    Lilienthal may have been a slow learner in the endgame, but he had an even record with Capablanca: +1 -0 =2

    I've never even seen it occur once...hard to believe Andrei had it happen to him three times...

    its impossibile because think about the last move fro white that u understand

    What about if the black king is for example on h1 the white King is on g3 and the two white knights are on f2 and h3

  • #29

    This position is interesting because White can win even though the black pawn has advanced well beyond the Troitsky line.

    White to play and win.

    Well, in some cases it can be forced, if Black has a pawn

     

    you have to get the king to the corner first mate. and how can you do that with 2 knights?

    its hardly doable with a knight and a bishop.

    White to move? That's a bit odd.

     

    In any case, this position isn't reachable unless Black is being highly cooperative and/or a total idiot...

     

    EDIT: Ninja'd by marvellosity. But what you said isn't quite true - the position can be legally reached, but it requires Black to help.

    The position is not only legal but forcible- E.g. White's quickest win from this position is as shown.

    With the Black king on a1/h1 I've several times finished up on both sides of the corresponding positions while practising the two knights v. pawn endgame.
