TRANSPOSITION
ENGLISH OPENING to RETI OPG. (Centre Counter V.)
White's KKt took control of the dark Q4+K5(d4+e5) centre to enable 3.P-Q4 without a forced 4.P-Q5.
Black advances his Queen's Pawn to the centre, freeing his QB and challenging White's QBP. Seen more via a Reti, it is regarded as inferior to other moves as White can gain a tempo. B-Alt.
