The English Attack is a brute-force all-purpose attacking setup characterized by White's moves Be3, Qd2, f3, g4, h4, O-O-O, Rg1, and crack open the kingside, in some order. It has been before seen in the Dragon, the Richter-Rauzer, and the Scheveningen, so it is nothing new. White attempts to open lines to Black's king on the kingside, castling long to ensure his own king safety. Black, meanwhile, attempts the same thing on the queenside, with an extremely sharp game. Kingside attack, however, is not the only idea. White often occupies d5 with a knight. When the knight gets chopped off, White recaptures with the pawn, following up with a maneuver of the b3-knight to a5 and then c6, occupying the other light-squared hole! After playing these moves White often ensures his own king safety, and can proceed to attack at his leisure.

Black invariably plays ...Be6 here, but ...Be7 is another move-order, and is good as long as Black intends to follow up with ...Be6. It is vitally important that Black cover the d5-square.
