It's important to note that Ng5-e4 is a threat. It's worth Black's while occupying d5 and the knight is the best man for the job.

This was not a trick question and the simplest course of action is clearly the best. Black should pressure the c2-pawn and with ... b7-b5 as well as ...Bxc4 always available to budge the knight, Black's position should practically play itself! --- The game continued:
