In one of the problems in unit 10 module 3 of PCT I encountered this position:
White plays 1. Nxd4 and wins a pawn. That baffled me. I would have sworn that Nxd4 would lose a piece. Counting is obviously a weak spot of mine. Hence I intend to take some time off to formulate a narrative for this position. These are the kind of positions that GM Henrik Danielsen solves à tempo in blitz games.
