Smith-Morra Gambit

From Wikipedia, the free encyclopedia

Smith-Morra Gambit Accepted

In chess, the Smith-Morra Gambit (or simply Morra Gambit) is a gambit against the Sicilian Defence distinguished by the moves 1. e4 c5 2. d4 cxd4 3. c3 (the moves are given in algebraic notation). It is not common in Grandmaster games, but at club level chess it is an excellent weapon.

How to play it

1.e4 c5 2.d4 cxd4 3.c3 dxc3 4.Nxc3

White sacrifices a pawn to develop quickly and create attacking chances. In exchange for the gambit pawn, White has a piece developed and a pawn in the center, while Black has nothing but an empty space on c7.

It would be nice if White plays the pawn to h3 now or on the following move to keep Black's bishop off of g4. (It should be noted that the above line is just one path of many that the game can take.)

Recommended over Nc6 in order to set up for castling on the king side sooner. It is also more aggressive and attacks the pawn at f2, expecting white to also castle on the king side eventually.

[edit] Smith-Morra Gambit Declined

Smith-Morra Gambit Declined: Transpose to Alapin Sicilian

1.e4 c5 2.d4 cxd4 3.c3 Nf6

If black wants to refuse the gambit, he can do so with 3... d5 or 3... Nf6, both of which transpose to the Sicilian Defense, Alapin Variation (usually introduced by the move order 1. e4 c5 2. c3).

3...Nf6 is a transposition to the Sicilian Defense, Alapin Variation

Alternatively, 3... d3 is the Smith-Morra declined proper, and leads to unique lines.
