Ne5 $1 {the key position of the KIESERITZKY GAMBIT - White moves the knight several times but gains the g4 pawn or the one on f4, at times losing the e4 pawn. The pawn push to h4 weakens White's kingside (in some variations a black knight comes to g3 via h5), but Black's king is also in a rather precarious positon. As a result the continuations that result are tactically complex and have strategic possibilities for both players. Black can continue with 5...d6, sacrificing the g4 pawn in exchange for good piece play after 6. Nxg4 Nf6, 7. Nxf6 Qxf6, or he can play classical - notes from COE, New In Chess} Nf6 6. d4 d6 7. Nd3 Nxe4 8. Bxf4 {The key position of the Classical Variation of the KGA. It seems to go against common sense to concede the e4 pawn for the one on f4: in addition Black has an extra pawn and an active knight on e4. Nonetheless, White receives good compensation: Black's kingside has many weaknesses, the g4 pawn, even though a material advantage, has the negative quality of restricting black activity on the wing, and perhaps Black would be better off without it(as in the case in the 5 ... d6 variation). In addition, White's rooks on e1 and f1 will exert unpleasant and ongoing positional pressure. This is also the case in variations in which the queens are exchanged. Black almost always castles queenside. White sometimes castles queenside too, and on other occasions he moves the king to d2 or otherwise to f2. In conclusion, after 8 ... Qe7 or 8 ... Bg7, the position is dynamically balanced. - notes from Chess Openings Essentials, New In Chess, GM Komarov, GM Djuric and IM Pantaleoni}) 4... g4 5.
