, remaining four pawns up. In either case, White has a clearly winning position.

Since taking the knight is fatal, after 3.Nxe5 Black should instead play 3...Qe7!(Other Black third moves, such as 3...d5, lead to 4. Qh5+! g6 5. Nxg6!) After 4.Nf3 (4.Qh5+? g6 5.Nxg6 Qxe4+ 6.Be2 Qxg6 leaves Black ahead a piece for two pawns) Qxe4+ 5.Be2, Black has regained the pawn but has lost time and weakened his kingside, and will lose more time when White chases the queen
Queen (chess)

, St. Petersburg 1897.

The fact that Black can only regain the pawn with 3...Qe7! shows that 2...f6? did not really defend the e-pawn at all. Indeed, even a relatively useless but non-weakening move like 2...a6?! would have been less risky than 2...f6?. After 2...a6?! 3.Nxe5, Black could still regain the pawn with 3...Qe7 4.d4 d6, and would not have weakened the king-side and deprived the king knight of its best square.

 instead, more logically, reserved the term "Damiano Gambit" for the knight sacrifice played by White on the third move: 1.e4 e5 2.Nf3 f6 3.Nxe5. Staunton referred to 1.e4 e5 2.Nf3 Nc6, a highly respected move then and now, as "Damiano's defence to the K. Kt.'s opening".

The greatest player to play the Damiano in serious master competition was Mikhail Chigorin. As noted above, he played the 3...Qe7 line in a game against Emmanuel Schiffers at Saint Petersburg 1897. Chigorin lost his queen on move 10, but Schiffers played so weakly that Chigorin later missed a brilliant forced mate and only drew

In chess, a draw is when a game ends in a tie. It is one of the possible outcomes of a game, along with a win for White and a win for Black . Usually, in tournaments a draw is worth a half point to each player, while a win is worth one point to the victor and none to the loser.For the most part,...
