COAT: Counter-Attack: In response to an attack of the adversary, an aggressive action generally organized on another front. Checking the opponent's King is a particular form of counter-attack, as it is possible to see in some openings. You find a typical example in the Semi-Slav, Meran Defense, Stahlberg variation [D49-q] : 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 c6 5.e3 Nbd7 6.Bd3 dxc4 7.Bxc4 b5 8.Bd3 a6 9.e4 c5 10.e5 cxd4 11.Nxb5 Nxe5 12.Nxe5 axb5 13.Qf3 The last White move is an aggressive answer; the White's Queen attacks directly the unprotected a8-Rook and simultaneously creates a potential threat on the f7-pawn. Nevertheless the classical Black's retort is: 13...Bb4+ (Chess War Terminology - NCT XVI - "Offensive strategy").

An offensive action made during the opponent's attack.

an offensive action made against the right-of-way, or in response to the opponent's attack.

An attack made in response to an opponent's attack ( may be out-of-time).

An attack launched by a defending team immediately after it regains possession of the ball. A counterattack in soccer is equivalent to a fast break in basketball.
