QGD. TRANSPOSITION
(to CATALAN) to SEMI-TARRASCH/SEMI-SLAV DEF.
Black's KP and KKt tripled his QP support, furthered his K5(e4) control and freed a KB path.
White rather tamely sets his King's Pawn on K3(e3) freeing his KB to defend his QBP, rather than play a principled 4.B-KKt5 or the Catalan. W-Alt.
