    Something interesting I found while reading a book about the beginning of chess composition.
    White to play and win:

    Nice. An interesting 2nd move.
  3. 01 Jul '05 17:40
    Not too difficult. Black only makes forced moves.

    KxN Qa1; h3 Qa2; h4 Qa1; h5 Qa2; h6 Qa1; h7 Qa2; h8=N Qa1;
    Nf7 Qa2; Nd6 Qa1; NxP Qa2; Na5 Qa1; NxR++

    Yes, odd or even.

    No, not too difficult. It was made by Otto Blathy famous not only with his mostrous chess problems (mate in 100+) and studies but with his inventions in engineering.

    Okay, here is another from that period (around 1920's) by another author. Pawns only:

    How about 1.Kf2 Kg4 2.Ke3! h5 (h6) 3.Kf2 Kf4 4.Kf1 Ke3 5.Ke1 f2+ 6.Kf1 h4 (h5) 7.h3 (h4)=. Looks a bit simple, but I don't see how else Black is going to make any progress. The idea for white is to make black use his h-pawn tempos first, so that he doesn't get zugged into playing Kg2 later.

    Okay that was easy and as I see from your solution not very correct The author was Grigoriev famous for his pawn studies.
    White was supposed to play 4.Ke1! after 2...h6 but I really cannot see a difference.
    Okay, another piece, this time however the question is:
    Can White draw? :

    You gave up too soon! It appears 4.Ke1 is indeed forced.

    If 4.Kf1?? Ke3! 5.Ke1 f2+! 6.Kf1 Kf3! wins for Black. White is forced to move his h-pawn.

    Okay let's see:
    7.h4! and now what? 7...h5 stalemate; 7...Kg3(e3) 8.h5=; 7...Kg48.Kxf2=

    [b]Can White draw?

    [fen]1k3B1r/N7/7P/8/3n4/7K/1b6/8 [/fen][/b]
    I don't have all variations yet, but I believe yes,white can draw with 1.Bg7 Rh7 (otherwise Bxd4+ and the fork on c6) 2.Kg4 Kxa7 (to be analysed what happens after other moves) 3.Kh5 Nf5 (Ne6? but I think that too will draw) 4.Bxb2 Rxh6+ 5.Kg5 Rh2 6.Be5 Rf2 7.Bf4 Nd4 (only move to escape from Be3+) 8.Be3 and black cannot get out of the pin without losing the knight. He can try 8. ... Rf5+ 9.Kg4 Rd5 10.Kf4 Kb6 but that won't help 11.Ke4 Kc5 12.Kd3 Rd6 (or other move on d-file) 13.Kc3 etc...

    Anyone helps for the other variations?
