|Alekhine–Chatard Attack Declined, White forces an attack after 6...h6 7.Bxe7 Qxe7 8.f4 a6 9.g4.
}}
* 4...Be7 5.e5 Nfd7 used to be the main line, even though the Burn Variation has overtaken it in popularity. The usual continuation is 6.Bxe7 Qxe7 7.f4 0-0 (not 7...c5? 8.Nb5!) 8.Nf3 c5, when White has a number of options, including 9.Bd3, 9.Qd2 and 9.dxc5.
* An alternative for White is the [[gambit]] 6.h4, which was devised by [[Adolf Albin]] and played by Chatard, but not taken seriously until the game [[Alexander Alekhine|Alekhine]]&ndash;[[Hans Fahrni|Fahrni]], Mannheim 1914. It is known today as the '''Albin–Chatard Attack''' or the '''Alekhine–Chatard Attack'''. After 6...Bxg5 7.hxg5 Qxg5 8.Nh3 Qe7 9.Qg4 g6 10.Ng5 (the reason for 8.Nh3 rather than 8.Nf3 is to play Qg4), White has sacrificed a pawn to keep the black king in the centre, as castling neither queenside nor kingside appears safe. Another point of the gambit is that Black's natural French Defence move 6...c5 runs into 7.Bxe7 when Black must either move the king with 7...Kxe7 or allow 7...Qxe7 8.Nb5! with a dual threat of Nc7+, winning the rook on a8, and Nd6+, when Black's king must move and the knight is very strong on d6. Black may decline the gambit in several ways such as 6...a6 and 6...h6. After 6...a6, White can continue to play for an attack with the aggressive 7.Qg4! threatening Bxe7 and then Qxg7. Black is forced to eliminate the bishop with 7...Bxg5 8.hxg5, opening up the h-file. A wild game with unsafe kings is sure to ensue. 6...h6 is a safer declination of the sacrifice, forcing the bishop to trade with 7.Bxe7 Qxe7 after which White may continue to try to attack on the kingside in anticipation of Black castling kingside (since queenside castling is undesirable due to the need for c5) with 8.f4 a6 9.g4 with a menacing attack.
