Decoy (chess)
In chess, decoying is the tactic of ensnaring a piece, usually the king or queen, by forcing it to move to a poisoned square with a sacrifice on that square.

Black to move
Example
In the diagram, with Black to play, illustrates two separate decoys. First, the white queen is set up on c4 for a knight fork: 1... Rxc4! 2. Qxc4. Next, the fork is executed by removing the sole defender of the a3-square: 2... Qxb2!+ 3. Rxb2 Na3+ 4. Kc1. Finally, a zwischenzug decoys the king to b2: 4... Bxb2+. After either 5.Kxb2 Nxc4+ 6.Kc3 Rxe4, or 5.Kd1 Nxc4, Black is two pawns ahead and should win comfortably.
Perhaps the most celebrated game featuring a decoy theme is Petrosian vs. Pachman, Bled 1961,[1] which also involved a queen sacrifice.
gollark: Well, if nothing else, using API access you could automatically work out the ToD from the hour information.
gollark: Not really. It's what it must use internally.
gollark: I don't know why TJ09 insists on such imprecise information.
gollark: Well, they cannot.
gollark: *hours now
