Black's best chance to sneak a win in the ending to Game 7080453 came at move 53. Players often have the idea of the opposition so firmly set in the their head that they can be tricked into moving their king out of the box:
54. Ke3?? is a blunder, Kc3 holds the draw, though Black still has a few more tricks.
Great minds thinking alike here Fat Lady.
I saw this last night and was going to make a comment but not feeling too well
A nice brutal entertaining game.
I was going to point out in this postion (Black to play)
He can force this postion with White to play.
Which is a simple Black win. Opposition allows Black to pick up,
without much thought, the a & b-pawns.
And if you are watching Braindog - everyone tries to win that lone Rook pawn
ending when first confronted with it. I know I did.
Game coming up but have to make White move first as Black cannot
move first in the RHP game moving thingy.

is it actually possible to mate a lone king with king and pawn? sorry but not sure
The main exception to the 'certain win' is when the pawn is a rook pawn (i.e. on the a or g file), when it is sometimes possible for the defender to draw by getting his king to the opponents queening square, where he can sit and move backwards and forwards without fear of being ejected.
There are other exceptions that are complicated, and to do with the defender being able to stop the attacking King stepping infront of his pawn. Here the defender can stop the pawn advancing and bring about a draw.
You want your king to be on one of the 3 critical squares in front of the pawn (c4,d4,e4). The reason for this is because from those square it can protect the pawn as it moves up the next 3 ranks. In this position the black king stops the white king from doing so.
Although it can be said that both players are in zugzwang, which means it is to the player's disadvantage to have to make a move. If it is black's turn to move and plays Kc5 he's left the e4 critical square and white's king can move there. If white uses the same technique there's a guaranteed win.
If it is white to move and plays Kc3, black will play Kc5 and white can make no progress. If he pushes the pawn, black makes the moves that don't allow the white king to control the critical squares and will eventually lead to this:
Where it is white's turn to move and the only move he can make without losing the pawn is Kd6 and that's stalemate, so it's a draw either way.

If white falls for Ke3, doesn't this still draw? or have a missed something on move 56?

It's still drawn even after 56. ... b3. Black can't get to that white a3 pawn. Any attempts at pushing Black's b-pawn when the White king is in the corner (a1 or b1, makes no difference) must be done when the Black king on d3 (White will be stalemated if his king is on a1 as soon as Black plays Kc2), so when the b-pawn moves to b2 White plays his king to a2, Black moves his king to c2 to protect the queening square and it's stalemate!
There are no tricks based on not taking White's c-pawn in order to avoid stalemate!
