Tactics true or false #1
Tactics true or false is a puzzle where I give a diagram and a playing line that may or may not be winning. If it is true, prove it (by knowing all the variations), and if it is false, find a counter example.
Black will play 1... Nbxd5 2. exd5 Nxd5 and the knight is attacking both the queen and the undefended bishop, since the queen can't go to a position to protect the bishop, black will take the bishop on c3 and be ahead by two pawns.
True or false?
