TRANSPOSITION
PILLSBURY DEFENCE to ALEKHINE'S DEFENCE
White's KPawn under threat moved on (rarely) to attack Black's QP and KKt.
Unusually, Black transposes towards the Modern Variation of Alekhine's Defence by moving his king's-side Knight to Q4(d5), rather than (normally) choosing 3..PxP to White's cost. B-Alt.
