TWO KNIGHTS DEFENCE - Knight Attack
The Ulvestad Variation
White's KP removed Black's QP to attack his QKt.
Black sacrifices the earlier pawn and advances a QKtPawn counter-attack to deflect White's light bishop from its KBP target. Inferior to 5..Kt-QR4. Alternative 5..KtxP?! is an instructive error. B-Alt.
    White  Black	White  Black
