Just another game

This took place in one of my recent blitz games. I was happy to keep myself calm and came out with a material advantage.

Any analization is welcome.

This position is won for black. After 10. ... c3, white has no way to prevent black from queening except sacrificing his rook.

to my defense I would say

3. ... Be5! refutes your line. The best black can do is win black's a and b pawns.

After 3... Be5 White's response will be 4.Rc6 4...Bf4 5.d7 winning for White.

3. ... Be5! 4. Rc6? Bxd6 5. Rxd6?? c1(=Q)+ 6. Rd1 Qxd1#

Franknstein, don't be too upset by eebster's analysis... Black resigned a won game!

Ok I give up.

Eebster u convinced me that I was lost here.I was lucky not to have u as my opponent in this game.

It's kind of funny how the solution of the puzzle leads to a win and a lost position for white!

To be fair, I had to use my computer to make sure. But after c3, black has the bishop pair to help his passed pawn, so I probably could have figured this out on my own (obviously I didn't use it for the variations, anyways). I also had to show that after the trade of the rook and d pawn for the c pawn, black could win with his bishops. That's pretty easy, though, since the black square bishop can eat white's a and b pawns with impunity.

And for what it's worth, I think you played the exchange correctly. I don't know of any better endgame you could have reached, and this one at least seems uncertain at first glance. I still can't figure out why your opponent resigned, though.
