Improve Your Chess: First Learn End! - Heisman-Amateur 1967

Black, the higher rated amateur, plays an erroneous ..h6 in a Richter Rauzer Attack and loses a pawn.  White is able to trade into a favorable endgame where both players misplay, each dropping a pawn, but leaving White with an easily winning King and five pawns vs King and four pawns endgame. White displays good technique to wrap up the win.
