Solution to Problem # 45

This position is from Bernstein-Capablanca, as found in Chess Traps: Pitfalls & Swindles, by Horowitz and Reinfeld. Black proceeds as follows:
1... Nxc3 2.Rxc3 Rxc3 3.Rxc3


Now here Black must be careful. At first glance, he might want to continue with 3... Qb1+ 4.Qf1 Rd1, but White follows with 5.Rc8+, with mate to follow.

Instead, Black plays 3... Qb2! and White cannot protect both his rook and his queen.
