TRANSPOSITION
FRANCO-INDIAN (Keres) to DUTCH (Rubinstein V.)
White developed his QKt to a pinned QB3(c3), interposing to relieve Black's early bishop check.
Black transposes into a Rubinstein line of the Dutch by advancing his King's Bishop's Pawn to KB4(f5) to take full control of White's K4(e4) (the pinned knight being no protection). B-Alt.
