Teehee, I just resigned in this position as black .  Then I realized what I'd done .  Oh well, I had three seconds on the clock left...  I would have lost on time anyway.

White has just played 1. c6, sacrificing a pawn.  How should black respond?

Ke1, I think.

Capture the f pawn with the King, the c pawn with the Bishop, and white can't win with the h pawn and dark squared bishop. Don't even try to defend your own h pawn, just run your King to h1. (All this is assuming the co-ordinates in your diagram is the wrong way round)

[edit] Scratch all that, the co-ordinares are OK, I need coffee. But the basic idea is the same.

Kd8, and the King will take care of the c pawn, the Bishop will take care of the f pawn, which leaves a rook pawn and wrong colour bishop

Be6 I would suppose

Rooperi, yes, that's what I saw also .

As for the coordinates, they seem to be correct for me, the reverse of what it seems you are seeing.  Hmm...  That's weird.

But, yes, the point is that even if I lose all my pawns, I can still get a draw because of the resulting wrong color bishop in the rook pawn endgame.  After Kd8 (or Ke1 if the board is messed up), white's c-pawn will fall, and white can never advance his f-pawn without losing it to the bishop sacrifice.  Black can then just stay at b7 and a8 and wait for white to finish collecting black's pawns.

 

Ivandh, 1... Be6 could work, but after 2. c7, you still have to see the idea of 2... Kd7 anyway (and if white tries 3. Bb6 to protect the pawn, 3... g1=Q+ simply trades pawns and draws).

I love this ending, I've swindled a few halfpoints on this site already. I think I even posted one ending here....[edit] Yes, I did:

Ooh, very nice, rooperi!  Excellent use of endgame knowledge.
