White to move and win. Are you capable to find the right way to the whole point? It is not easy, isn’t it?

  2. Hello Petr,
    As the Knight’s tour was “Kolty’s” specialty, I have specialized in the K, N & B vs K ending. That is what this translates into. First White must blockade the “c” pawn (not enough time to capture it yet) and then control the “b1” queening square with the N. The move order is 1.Kc4, 2.Ne4 and 3.Nc3. No matter what Black does, he will never be able to promote the pawn. White must just be careful to avoid any stalemates, which he can do easily enough, then after capturing the “b” pawn, pick off the “c” pawn and mate with K, B and N. This is easily enough done within the 50 move limit if you know the procedure (drive the opposing K to the edge and then to the corner of the color of your B). I have done this in a tournament game.
    A sample line would be 1.Kc4,b3; 2.Ne4,Ka2; 3.Nc3+,Ka3; 4.Bb5,Kb2; 5.Bxc5,Ka1; 6.Nd1,Ka2 (if 6.., b2; 7.Bd4); 7.Bd4, b2; 8.Nxb2 winning. (If 3…, Ka1 in this line, then 4.Na4, b2 5.Bc3; Ka2; Nxb2 wins) Another sample line would be 1.Kc4, Ka2; 2.Ne4, b3; 3.Nc3+, Ka1 (if 3…, Ka3, 4.Bb6, b2; 5.Bxe5 mate), ((or if 4…, Kb2 in this line, 5.Bxc5, Ka1; Na4, b2; 7.Bd4; Ka2; 8.Nxb2 wins)); 4.Na4 etc. as before. I have gone through numerous lines and variations, too many to list, all with the same result, i.e. Black can never promote the pawn and hence will ultimately lose.
    I thoroughly enjoyed working on this problem!
