Head-to-head golf scored hole by hole: win the hole with the lower score and you go '1 up'; total strokes don't matter. The match ends when one side leads by more holes than remain — a '3&2' win means 3 up with 2 holes to play. Why people love it: a triple bogey costs exactly one hole, so you can be aggressive, concede putts, and rally from a bad stretch. It's the format of the Ryder Cup and most club championships.
