Greek Gift Sacrifice

The Greek gift is a named sacrifice: a bishop captures the h7 (or h2, for Black) pawn right next to a castled king, giving up material for an attack rather than for an immediate tactical win. It's one of the few tactics on this site that isn't really "one move" — it's a specific, well-known plan with a recognizable setup, a standard follow-up, and conditions that have to be checked before it's actually sound.

What has to be true before the sacrifice works

The bishop capturing on h7 only creates real problems if White (or Black, on the other side) has enough left to attack with afterward. The two pieces that matter most are a knight that can reach g5 with check, and a queen that can swing over to h5 (or h4) to join the attack along the h-file or the b1-h7 diagonal. Without both of those readily available, the sacrifice is often just a bishop for a pawn — a bad trade with nothing to show for it. Before playing it, count your remaining attackers, not just the invitation itself.

Why the king almost always has to accept

Declining the sacrifice by moving the king to the corner instead of capturing isn't automatically safe, but it isn't automatically losing either — it depends heavily on what else is happening in the position. Capturing is usually the more natural response because refusing means giving up a pawn for nothing in return, on top of leaving the bishop alive to keep pressuring the same diagonal later. Whether declining is actually the better defense is a real, position-specific question, not a fixed rule — it's worth calculating both branches rather than assuming the king must take.

The knight check is doing more than it looks like

Once the king has captured on h7, the follow-up knight check does two things simultaneously: it forces the king to move again immediately, using up another tempo the defender doesn't have to spare, and it lands on a square that would have been completely unreachable safely before the h7 pawn disappeared. The sacrifice didn't just remove a pawn — it removed the exact piece of cover that used to make that square dangerous for the knight to use.

Judging whether the attack is actually winning

A Greek gift that doesn't lead to a forced win of material or mate isn't automatically a mistake — a strong attack for a piece can be worth playing even without a forced conclusion calculated to the end, provided the defender's king stays permanently weaker for the rest of the game. But "this looks scary" and "this is actually winning" are different questions: count the attackers you have left against the king versus the defenders that can realistically arrive to help, rather than assuming the sacrifice works just because it's a known pattern.

The queen-and-knight combination in the diagram is a specific, deliberate battery-style buildup aimed at the exposed king — worth reading together with this page, since recognizing when you have enough attacking pieces available is really the same skill in both cases.
