(to) Kieseritzky Variation
White developed his KB to QB4(c4) early, a gambit move to threaten Black's weak (ie. less defended) KBP instead of taking his unprotected doubled QP.
Black advances his Queen's Bishop's Pawn to a supported QB4(c5) to defend his newly doubled QP, a rare alternative to 4..Kt-QB3 transposing out. B-Alt.
