    Is it possible for black to win, assuming perfect play on each side?

    (I do not know, this was a blitz game. I lost - I had only 3 total minutes left.)

    It's not looking too good for black. I've seen games where three pawns win against a rook. Four is pushing it , but 5!? It would be tough, but the only way I can think of that you would easily attain the answer is to put it into a program.

    No. It is not possible with perfect play on both sides.. If white were to completely suck, he/she would lose.

    White could be retarded and still win.

    if black moves first, with perfect play, I see a draw by insufficient material. If white moves first, black looses.

    2 connected pass pawns are stronger then a rook in the endgame...let alone 5 pawns

    Only if they're far enough advanced. They need the king's protection until they reach the sixth rank, and even the king probably isn't enough if you back them up a couple more ranks.

    Why did you do it that way?

    What was wrong with 1...Kc4, with mate in 4 at most?

    i was thinking this too, but i think white can avoid letting black maintain the opposition.

    Is this in response to my post?

    What opposition? It's your standard mate with Rook and King.
