    a) Capturing the pawn leads to a draw.
    b) I tried to save the a6 knight by playing 1. ..Nc7, which threatens mate by 2. .. Bb6#, if black promotes. Looked nice!
    c) Soon i noticed, that black must promote to a knight here. Then i must move my king, allowing the black king to escape the mate.
    d) After 2. a1N+ Kb2 3. Nb3 i can’t take the knight, or else i will run into a stalemate after 4. Bc5 Bxc5. Everything else after 4.Bc5 seems to be drawn, too.
    e) So i can’t take the knight, but what else? Too hard for me this time. Perhaps i try it later this week.

    1.Bd4 is also a draw (Kxa6 Kxb4 Kb7 Nb6 a1Q Bxa1 Kxb6)

    1.N6c7 2.a1N Kb2 3.Nb3 Nb6 looks complicated 4.Bc5? Kxb3 5.Bxg1 Nc4 is a mate :)

    But now I have the final idea I guess

    1.N6c7 2.a1N Kb2 3.Nb3 Kxb3 4.Bc5 Nb6? 5.Bxg1?? Nc4# But of course you could simply take the knight :(

    so 4………Nd5!? 5.Bxg1 Nac7 6.mmmh Bh2 and now?

    Ok, new idea 1.N6c7 2.a1N Kb2 3.Nb3 Kxb3 4.Bc5 Bh2! 5.Bd6 Nb6! (6–>Nc4#)
    a)6.Kxb6 Bxd6
    b)6.Bxc7 Bxc7
    c)6.Bxh2 Nc4#

    SOLVED! :)

Got something to say?
