Part One: Multiple attacks
1.1. Double attack: Greco vs NN, 1620. 14. Be6+ directly attacks the black Q while uncovering a check by the R. The check cannot be removed, except by interposing the black Q (which loses it for nothing) or by moving the K (as in the text).
1.2 Treble attack: a move which unveils two discovered attacks and directly attacks another piece. No example yet.
Part Two: Pins
1.2: Absolute Pin: Uhlmann vs Larsen, 1971. 36. ... Ba6 wins the White Q, because the White B, being absolutely pinned to the White K, no longer defends her.
1.3: Pin to a square: Greco vs NN, 1620. 9.Re1 wins at least the black Q, because she is pinned to the mate on e8 (see text).
1.4 Double pin: absolute pin/pin to a piece: Robatsch vs Jansa, 1974. After 12. Qd2 the Black B cannot leave the a1-h8 diagonal, as this would uncover a check by the White B, and cannot leave the e1-a5 diagonal without exposing the Black Q to capture by the White Q.
Part Three: Forks
1.5: Knight Fork: Chigorin vs Charousek, 1896. 25.Ng5+ attacks the Black K and Q simultaneously.
1.6: Deflection: J Vetemaa vs Shabalov, 1986. After 20. ... Qb5, the Black Q cannot be taken, as if the White B leaves the defence of b3, Nb3# follows.
1.7. King Hunt: Greco vs NN, 1620. 16. Qg5+ starts a string of moves which force the black K out from behind his pawn cover to the centre of the board were White can deliver checkmate.
