Elephant Gambit

The Elephant Gambit, also known as the Queen's Pawn Countergambit, arises when Black answers the attack on e5 not by defending it but by striking at e4 with 2...d5. The aim is to open lines quickly and seize the initiative. The drawback is that the center opens while Black is effectively a tempo behind, and White can capture either pawn with advantage, so the gambit is regarded as unsound. The engine gives White a slight edge. In online practice, however, results are almost even, and Black even scores marginally better, which reflects how many traps the opening sets and why it serves as a surprise weapon.

The most common reply is 3. exd5, played in about half of games. Recapturing with 3...Qxd5 lets White gain time with 4. Nc3 and build a large lead in development, so Black usually prefers 3...e4, the Paulsen Countergambit, which harasses the f3-knight. After 4. Qe2 the pin on the e-pawn holds the knight in place, and following 4...Nf6 5. d3 Qxd5 6. Nbd2 White remains a pawn up after 6...Nc6 7. dxe4 or 6...Be7 7. dxe4 Qe6. The choice of 6. Nbd2 rather than 6. Nc3 sidesteps the complications that follow 6...Bb4. The Maróczy Gambit, 3...Bd6, protects e5 and leaves the d-pawn behind; after 4. d4 e4 5. Ne5 Nf6 6. Nc3 O-O 7. Bc4 White is clearly better, though without a direct attack.

The alternative 3. Nxe5, chosen in about a fifth of games, is also strong. After 3...dxe4 4. Bc4 the pressure on f7 is severe, and the Wasp Variation, 4...Qg5, counters by hitting the knight and g2; in Lob–Eliskases, a 1929 correspondence game, White answered 5. Bxf7+ Ke7 6. d4 Qxg2 7. Rf1 Bh3 8. Bc4 Nf6 9. Bf4 and later won. The other main defense is 3...Bd6 4. d4 dxe4 5. Bc4 Bxe5, when 6. Qh5 creates the twin threats of Qxf7# and Qxe5. Black is pushed toward a queen trade, for instance 6...Qe7 7. Qxe5 Qxe5 8. dxe5, and White enters an endgame with the bishop pair and a small but lasting plus.

The less frequent 3. d4 gives White the best results of the three main replies. Across all lines the play is open and tactical, and Black's prospects rest largely on the opponent's unfamiliarity with the refutations.
