TRANSPOSITION
VIENNA GAME (Anderssen Def.) to THREE KTS. OPG.
White developed his KKt to KB3(f3) to prevent 3..Q-R5, threaten Black's KP and support 4.P-Q4.
Black is unwise to transpose into an inferior Three Knights Opening line by developing his Queen's Knight to QB3(c6) in support of his KP. B-Alt.
