    Now that I think about it, I should have gotten that. Oh well...

    Took me a little long to find it but I got it. Black has all the chances while White has no constructive moves to make. Note a rook vs. bishop is a theoretical draw.

    Normally, this endgame is a matter of technique, however this and other endings will pass through positions where the winning side must find one and only one move or the game will slip into a draw.

    It's a good problem, since it requires an understanding of the position. Black must keep his pawn if he wants to win, and he must see that white is threatening to advance his own pawn, encouraging an exchange of pawns.

    1... Ke5! prevents f6 immediately, and shoots for g5 square to relieve the rook from the protection of the h4 pawn, going for a win. 1... Kd5? allows 2. f6 Kd6 3. Bg4 etc...

    Nice end game problem

    I treated this like a study with "black to play and win" and could not find anything. Sure Ke5 keeps black's chances alive but it might still be a draw after Bd2 - how does black make progress?

    integrator - the idea is to know that it's winning, rather than seeing all the variations leading to checkmate. The same way you know K+R vs K is winning, if you know what I mean (only here it is more complicated, of course).


    Normally, as you very well know, R vs B is a draw. But the presence of a pawn on each side allows the rook to exploit it's superiority over the bishop and force a win eventually (unless it is an abnormal position). You may as well replace rook with queen and bishop with rook to have the same result, only with amplified effect (this makes the win with the queen much easier).


    Here, after 1. Bc8? 1... Ke5! Black does not allow white to capture his h4 pawn, which is his winning card. His goal is to contain white, after which the win is inevitable. As I noted before, Black's first target is to get his king to g5, which frees his rook from the job of defending the h4 pawn, and from there - it is simply a matter of technique.


    It is hard to give specific lines, but here's one to try and make it a bit more clear that black is easily winning here:


    1. Bc8? (f6 draws) Ke5! (only winning move) 2. Bd7 (just hanging on to the pawn) Kf6 3. Bc8 Kg5 (first target completed) 4. Bd7 (4. f6 is best move, but that is clearly lost) Rf3+ 5. Kg2 Rd3 6. Bc8 h3+ 7. Kh2 Kh4 etc...

    Yes, 1.f6 is a draw. But you have the Black pieces, and you have to find the mistakes of your opponent.

    This is a "positional position".  Its also not a zugzwang.  Black's king is going to dance 3 three dark squares (to g5) holding white's pawn in a kind of cup with black greatly improving his K-position.  47s +5 and june by memory +9.
    Comments above and below asking how will black win.  April: difficult to describe in a few words so will try to condense in next comment.

    Black's strategy after he gets his king to g5 is to navigate his 3 pieces via dark squares to 3 particular dark squares.  Namely R to f2, K to g3, P to h2.  White cannot stop this not even by pushing his P after black's P enters h3 where loss of white's B for a pawn-trade loses for white.  
    Then:  if white's B is to stop black's h2-pawn from promoting black could R-take white's f-pawn with impunity and winning from there.
    If white's king is to stop black's h2-pawn from promotion with Kh1 then black would just lateral his rook.  Aiming at a dark checking square like a1 for example and its checkmate coming up.  Plan wrong?   Maybe I'll find out!

    forgot which way the pawn was headed

  • 19 months ago · Quote · #18


    The analysis board has an incorrect last move in the winning line (I believe).


    Shoopi has the last move correct in that line (86. ... Kh4). However, the listed move is 86. ... Kf4, which I think allows white to draw.

    How does black continue to win after the posted analysis?  It ends with a complicated position

  • 9 months ago · Quote · #20


    I believe this is the right technique to win.
