A rule of thumb for Black when playing against Spanish/Italian openings with a knight on f6: Don’t castle when your dark-square bishop is locked out by a pawn on d6; the pin created by the bishop on g5 against the knight on f6 tends to be very strong. Of course, if you know your theory, you’ll be able to wiggle out of the pin unscathed eventually, but for the less well-versed,having to defend against the pin is extremely annoying indeed. Hence, be wary of locking out your bishop and castling prematurely.
This works in very well in conchunktion (pun drum roll, please!) with the Bindelicious chunk.
