The Greek gift: the bishop sacrifice on h7

Published 28 October 2026

Castling makes the king safer, but it does not make it safe. One of the oldest and most common ways to break open a castled position is a bishop sacrifice on h7 (or h2, if Black is the attacker). It is called the Greek gift, after the wooden horse the Greeks left outside Troy: an offering that looks like a present and turns out to be an attack. The idea was described as far back as the early seventeenth century by the Italian writer Gioachino Greco, and it still decides games at every level today.

This article works through one model position. Every move sequence was checked for legality with a chess rules library, and the assessments ("White is winning", "this defence holds longer") come from analysis with the Stockfish chess engine, not from guesswork. The position itself was built for this page to show the idea clearly.

The model position

White to play. The bishop on d3 aims at h7, the knight on f3 can jump to g5, and the queen on d1 can reach h5. (White to move.)

Material is level. The position looks quiet: both sides have castled, the centre is locked by the pawns on d4, e5, d5 and e6, and Black is about to put pressure on e5. But look at the three white pieces aimed at the black king. The bishop on d3 points at h7. The knight on f3 is one jump from g5, where it would attack h7 and also e6 and f7. The queen on d1 has an open diagonal to h5. And the pawn on e5 takes away f6, the square where a black knight would normally defend h7.

The sacrifice

White plays Bxh7+, giving up a bishop for a pawn. Black has two legal replies: take the bishop with the king, or step to h8. Engine analysis shows White is winning after either, and declining with Kh8 is actually worse for Black, because the bishop stays on h7 and the attack continues for free. So the main line is the capture.

1.Bxh7+ Kxh7 2.Ng5+

After Bxh7+ Kxh7 Ng5+, the black king is in check and must decide where to go. (Black to move.)

The knight check is the point of the sacrifice. It brings a second attacker to the king with tempo, and it clears the way for the queen to come to h5. Black now has four legal king moves, g8, g6, h6 and h8, and the result of the sacrifice depends on which one Black chooses.

Retreat to g8: the queen arrives

The most natural move is back to g8. White answers with Qh5, threatening Qh7 mate, because the knight on g5 protects h7 and the rook on f8 blocks the king's escape.

1.Bxh7+ Kxh7 2.Ng5+ Kg8 3.Qh5

Qh5. White threatens Qh7 mate. Black can only delay it at heavy cost. (Black to move.)

Black can stop the immediate mate by moving the rook from f8 to give the king a square, but the queen and knight then attack f7 and h7 together, and engine analysis rates White's position as decisively winning. This is the line the Greek gift is famous for.

Retreat to h8: mate

Going to the corner is the worst choice. After Qh5+ the king must go back to g8, and Qh7 is checkmate.

1.Bxh7+ Kxh7 2.Ng5+ Kh8 3.Qh5+ Kg8 4.Qh7#

Qh7 mate. The knight on g5 protects the queen; the rook on f8 blocks the king. (Black to move.)

Forward to h6 or g6: the hardest defence

Stepping forward feels dangerous, and it is, but it is also how Black puts up the most resistance. After Kh6, White has several strong queen moves to choose from, and the engine rates White as winning. After Kg6, which was the engine's best defence in this position, White continues the attack with moves such as Qd3+, bringing the queen to the b1-h7 diagonal with check. Black can fight on, but the engine still gives White a large advantage. The king has been dragged out in front of its pawns, and that rarely ends well for the defender.

These forward king moves are where the Greek gift becomes difficult for the attacker in real games. Lines like Kg6 require calculation, not just a memorised pattern. That is a good reason to know the conditions below: if they are met, you can sacrifice with confidence and work out the details afterwards.

The conditions for a successful Greek gift

Trainers usually list a handful of conditions. None of them is an absolute rule, but the more of them are met, the more likely the sacrifice is to work. Check them against the model position:

The bishop has a clear line to h7. Here the d3 bishop reaches h7 through e4, f5 and g6.
A knight can reach g5 safely. If a black bishop on e7 or a queen on d8 could simply capture the knight on g5, the attack loses its main follow-up. In the model position, nothing black covers g5.
The queen can reach the h-file quickly, usually on h5, with nothing in the way.
Black has no knight on f6. A knight on f6 defends h7 and covers h5. The white pawn on e5 is often what keeps it away.
Black's defenders are far away. Here the black queen on c7, the bishop on d7 and both knights are on the queenside or in the centre, too far to help.

Run through the same list for your opponent whenever you castle. If a bishop, a knight and a queen can all reach your h-pawn in a couple of moves, it is time to defend: put a knight on f6 (or f3 for White), keep a piece covering g5, or play h6 at the right moment so the h7 square is no longer a target.

Why the pattern is worth memorising

The Greek gift is a good example of how pattern knowledge and calculation work together. Without the pattern, few players would even consider giving up a bishop for one pawn in a quiet position. With it, the idea comes to mind at once, and then the routine from how to calculate decides whether it actually works: list the forcing replies, check each king move, and count what you get. If you recognise the set-up but find a defence you cannot break, do not sacrifice. A Greek gift that fails leaves you a piece down with no attack.
