THE SCOTCH GAMBIT

Board Position
A variation of the Scotch Game (qv.) where White's violent attack on the centre is aided by the gambit of a pawn sacrifice. Board Position
Instead of recouping a lost Q4 pawn, White develops his KB before offering a second QB3 pawn (move 5w, left). The extra pawn is usually (but not always) accepted by Black.
White then goes on to target Black's weakest point KB2(f7) with an all-out Q+B+Kt assault (move 8wb, right), but Black if experienced should have no great difficulty in withstanding the attack.

THE SCOTCH GAMBIT ("Épine Dorsale")

 1. P-K4...P-K4
White
attempts to occupy the centre with his King's Pawn, opening diagonals for his KB and Q and attacking squares Q5(d5) and KB5(f5).
Black has the same idea, replying with a mutual King's Pawn in an open defence (so termed because in an open game the centre tends to become opened up by pawn exchange rather than blocked by close play).

 2. Kt-KB3...Kt-QB3
White
brings his King's Knight closer to the centre and attacks a pawn, as per the golden rule: always develop with attack if possible.
Black defends the pawn and develops his Queen's Knight.

 3. P-Q4
White
leaves the "Épine Dorsale" to start a violent attack on the centre with a vigorous Q-Pawn move forcing a pawn exchange.
 3. ...PxP
PxP is Black's best reply
, as 3..P-Q3 may not only prevent him castling but force him to waste a move protecting his KBP, and 3..KtxP may lead White to an advantageous Q-position.
