Montana Open - Round 4

Round 4 was perhaps the toughest one of the tournament. My opponent had a much lower rating, but he was a solid player who caught me napping and drew first blood when I left a center pawn hanging. That woke me up fast, and we went into a 70-plus move meat grinder that, fortunately, had me emerge victorious.

CORRECTION: I said at the end of my commentary that his king would be in zugzwang (i.e., having to make a bad move), but that's incorrect. The pawn simply falls to the rook regardless of what the king does.
