TRANSPOSITION
KGD. (Petrov's Def.) to ALEKHINE'S DEFENCE
Black declined White's KBP gambit with a rarer KKt development counter-attacking White's KP.
White transposes into the Maroczy Variation of Alekhine's Defence by pushing his Queen's Pawn out to Q3(d3), freeing his QB and thus defending both KP and KBP at a single stroke. W-Alt.
