    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.

             47 seconds for plus 5 points.

            This is a "positional position".  Heh.   

           This is not really a Zugzwang position.  I voted against that.        But this is positional play, not tactics.  Black's going to dance the three dark squares holding that pawn in a kind of cup as it were, greatly improving the position of his King.  

         But its asked, in the comments above, how will Black then convert his advantage?  Its positional, not tactical, but it doesn't look like a difficult plan.  April edit: what's difficult is how to describe it properly with very few words.  So I'll try to condense the info in my next comment.

            Black's strategy to convert his advantage to a full point, after he gets his King to g5, looks like, to then get his three pieces to three particular dark squares, namely his rook to f2, his King to g3, and his pawn to h2.

         How could white then possibly defend against both queening the hpawn, and mate?  If with the bishop, say with having his bishop at d5, Black could then rip the white fpawn with impunity.  Could Black win then?  It appears yes, because the white king and lightsquare bishop could not survive trying to stop the h pawn.

         If with the white king at h1 instead, then white would have to have his bishop controlling f1, to stop rook f1 mate.  Say with his bishop at e6.  But the White King is trapped.  Black would just lateral his rook, to aim at a black checking square, like h8 for example, and then white can say bye bye game.

          I don't think white can stop this plan.  Black will keep his pieces almost always on dark squares as he manoeuvers his 3 pieces to those 3 squares.  The only time he has to cross over, is when his pawn goes to h3, if white pushes at the same moment...its okay, white can't give up his bishop, for a pawn trade.

        Its all positional stuff, often easier than tactics, which have to be precisely calculated and timed.  The mistake made very often is not realizing that tactics and positional play go hand in hand, they're not in separate boxes.

    forgot which way the pawn was headed

           7 weeks later.  Timed not rated.

          Not enough clutter of pieces and choices in this one for me to miss the solution even though I forgot it.  But I'll never get to 1800 unless I figure out quicker ways to solve the cluttered ones.

         April edit:  whoops!  Looked at the beginnng like Pawn take King was an option....

    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.
