TRANSPOSITION
SICILIAN CENTRE GAME to OLD BENONI DEF.
Black declined the immediate QP to avoid the Morra Gambit and instead set his own QPawn on Q3(d6) to support his QBP, free his QB and deter 3.P-K5.
White transposes into the Old Benoni Defence by moving his central Queen's Pawn on to Q5(d5), reducing Black's QKt options. W-Alt.
