Chess: Understanding the Elephant Gambit Part I

1 e4 e5 2 Nf3 d5 3 exd5 e4 4 Qe2 Nf6 5 d3 Qxd5
6 dxe4 Qxe4 7 Nc3 Bb4 8 Bd2 Qxe2+ 9 Bxe2 O-O
10 a3 Bxc3 11 Bxc3 Nd5 12 Be5 Nc6 13 O-O-O Line




What's the game plan for Black?

Initially, Black sacrifices a pawn on d5 (2 ... d5)
so as to enable the advance e5-e4 (3 ... e4).
This maneuver gains space in the center and
harasses the f3 knight. Next, he regains the
proffered pawn through a Queen capture on d5
(5 ... Qxd5).


What's the game plan for White?

White first accepts on d5 (3 exd5) and then he
places his Queen on e2 (4 Qe2) in order to pin
Black's errant e4 pawn. Lastly, he builds up
pressure against e4 and compels Black to
relinquish his hold on that focal point
(5 d3; 6 dxe4; 7 Nc3; 8 Bd2).


1 e4



(i) Staking a claim on d5 and f5.
(ii) Enabling the f1 bishop to mobilize along the
f1-a6 diagonal.

1 ... e5



Black takes charge of d4 and f4, plus, he liberates the
f8 bishop along the f8-a3 diagonal.

2 Nf3



Development with attack. White threatens 3 Nxe5.

2 ... d5



Inaugurating the Elephant Gambit.
Black answers White's e5 threat with an attack on
the e4 pawn.

3 exd5



Prevention against 3 ... dxe4.

3 Nc3 is inadvisable because it allows the stifling
3 ... d4. For instance, 3 Nc3? d4 4 Ne2/4 Nb1,
forcing the knight back and leaving Black with a
good grip on the center. Not 3 Nc3? d4 4 Nd5? c6,
and the knight is lost. No better is 3Nc3? d4 4 Nb5? a6
5 Na3 Bxa3 6 bxa3 Qd6, ruining White's pawn structure
and weakening his control of the center.
