Borik Otto. Budapest gambit

Batsford, 1986. — 109 p. — ISBN: 0713452978 (1imp).The Budapest Gambit (or Budapest Defence) is a chess opening beginning with the moves 1.d4 Nf6 2.c4 e5. Despite a first game as early as 1896, it only began being played by leading players in 1918 after a win as Black by Grandmaster Milan Vidmar.The Budapest Gambit contains several specific strategic themes. After 3.dxe5 Ng4, there is a battle over White's extra pawn on e5, which Black typically attacks with...Nc6 and (after...Bc5 or...Bb4+)...Qe7, while White often defends it with Bf4, Nf3, and sometimes Qd5.In the 4.Nf3 variation the game can evolve either with Black attacking White's kingside with manoeuvres of rook lifts, or with White attacking Black's kingside with the push f2–f4, in which case Black reacts in the centre against the e3-pawn.In numerous variations the move c4–c5 allows White to gain space and to open prospects for his light-square bishop. For Black, the check Bf8–b4+ often allows rapid development.
