The sacrifice on h7

The key idea

The Greek gift demands its conditions: a bishop aimed at h7, a knight ready for g5, a queen with a fast route (h5 or the diagonal), and a rival WITHOUT agile defenders of the key squares. With the full list checked off, fire away; if one is missing, keep your bishop.

Example 1 · The complete Greek gift, step by step

French structure, Black just castled, the defending knight away from f6 — the list of conditions, all checked off. Watch the entire collapse.

1. Bxh7+ The Greek gift! The bishop for the h7 pawn. Run through the list before the jump: knight on f3 ready for g5 ✓, queen with the h5 square clear ✓, pawn on e5 taking f6 away from the defender ✓, and Black's knight on d7, far from the zone ✓. With the full list checked, this isn't a sacrifice anymore: it's an investment.
2. Kxh7 Accepting is the critical test (declining with Kh8 doesn't save it either: the engine still gives a decisive advantage, with the missing pawn turned into a free attack).
3. Ng5+ The second ingredient enters the scene: check, and the queen already has the door open.
4. Kg8 The natural retreat. The brave alternative Kg6 — walking into the storm — ends up hunted down by the queen and the pawns: no king survives out there with so little help.
5. Qh5 Third wave: the threat is mate on h7. Black only has one way left to keep breathing.
6. Bxg5 Giving the piece back: the bishop eats the knight to block the gale. Forced… and it was also in the recipe.
7. hxg5 And here shines the silent ingredient: the h4 pawn recaptures, and the ENTIRE h-file opens up for the rook on h1, with White's king not even castled yet — perfectly happy to live in the center while its rook shoots down the file. Material: level. Position: demolished. The engine rates it at over six points of advantage. This is the Greek gift with every condition met: not a trick — a certified demolition.

Example 2 · The incomplete list: when the Greek gift is a bluff

The vaccine, in one position: the same picture… with Black's knight on f6. ONE broken condition, and the sacrifice goes from demolition to a gift. Compare the two boards before you ever jump.

1. O-O White, with good judgement, does NOT sacrifice: look at the difference with Example 1 — Black's knight is on f6, guarding h7 and g4, and there's no pawn on e5 to kick it away. The list is broken: Bxh7+ here gives away the bishop for nothing (Nxh7 collects it and the attack dies on its own). Instead, normal chess: king home.
2. c5 Black plays their plan calmly. There's no storm to fear: their guardian is at its post.
3. c4 Honest central struggle, no fireworks.
4. Nc6 A normal game, a balanced board. The moral is already in plain sight: the Greek gift isn't a whim — it's a LIST. The defending knight off f6 (or evictable), your knight one jump from g5, the queen with a motorway, and reinforcements behind. Meet them all: you fire. Miss one: you keep your bishop and play chess. h7 bluffs have given away more pieces than any other move in the world.

Practice

The Greek gift's list is complete: bishop eyeing h7, knight ready, queen with a motorway, defender far away. Carry out the full demolition — all the way to opening the h-file.

1. The Greek gift, delivered! With the full list of conditions checked off, this is an investment with guaranteed returns. Run through your list: knight ready for g5, queen with a route, defender far away. The bishop already knows what to do.
2. Second wave: check, and the door to h5 open for the queen. The king now only gets to choose its cell. The knight was the second ingredient: jump with check, clearing the queen's path.
3. Third wave: mate threatened on h7. Black has only one option left: give the piece back to breathe for one more turn. The queen, to its motorway: the square from which it threatens mate on h7.
4. And the silent ingredient finishes the job: the h-file opens entirely for your rook on h1. Material level, position demolished, over six points of advantage per the engine. The complete Greek gift, carried out by your own hands — with the checklist as your licence. Recapture with the h-pawn: the rook on h1 has been waiting the whole game for this file.

The Greek gift sacrifice, mastered with its two faces: the demolition when the list is complete, and the discipline to keep your bishop when one condition is missing. That checklist — defender far away, knight ready, queen with a route, reinforcements behind — is worth more than a hundred brilliant games: it's the difference between attacking and gambling.
