    That was the first thing that I thought of. Passed pawns must be pushed!

    That's a fair start. But now try to look for ideas for Black, and try to refute your initial ideas... and then possibly look for further counters to Black's ideas and so forth. There's a bit more fighting to be done in this position. 🙂

    You're right. White has to worry about 1.g7 Be5 2.g8=Q Re1+. I'll have to look at this some more.

    1. g7 Re1+ 2. Bd1! Re8 3. Bh5 Rg8 4. Bf7 Rxg7 5. g6! =

    Overview:

    Opposite colored bishop. Two passed pawns that have crossed into enemy territory vs. rook. Another side note: white's bishop prevents the black king from imposing opposition, and the location of black's bishop illustrates how the location of a piece can obstruct the free passage of his own pieces. Black's king is also on the same color square as his bishop -- taking squares away from his bishop restricting his mobility.

    Analysis:

    a) 2. ... Rxd1 3. Kc2 and black can't prevent the pawn from promoting.

    b) 5. g6! traps the rook.

    Epilogue:

    Another example of how a passed pawn in the enemy's camp may be equal to a rook. Many other example illustrate how a pawn can even be stronger than a rook, e.g. Saavedra.

    you could block the final rook check with your bishop. that's actually the first point in this position.

    petrovich's line is the correct one. I was referring to the last position of his main line when I said beautiful:

    Yep, as soon as I saw petrovitch's solution, it was clear to me what you'd meant. It _is_ a nice position. Once the rook is trapped, the white king doesn't even have to do anything except make random moves. 🙂
