However, most of these bishop moves are defeated by 1 ... Rb6!. So, the key must be the one move that interferes with the b8-rook: <b>1 Bb7!</b>. And indeed it does solve this problem. Black can defend by moving something to d4, but each such move commits an error that White can exploit:<br /><b>1 ... Bd4</b> (interferes with the queen's guard of d5) <b>2 Sd5</b><br /><b>1 ... Rd4</b> (unobstructs the f3-pawn) <b>2 f4</b><br /><b>1 ... Qd4</b> (self-pins the queen) <b>2 Rxc3</b><br />The black queen has two more defenses, and each one allows a different double-check than the threat:<br /><b>1 ... Qd5/Qxd6 2 Rxc3</b><br />There are also two checking defenses, and White has answers for these, too:<br /><b>1 ... Qe4+ 2 Re5</b> (this is distinct from the threat due to being a pin-mate as opposed to being a double-check)<br /><b>1 ... Re4+ 2 fxe4</b><br />Finally, the rook has several more defenses seeking to exploit the anticipatory self-interference that the threat would make, but White has answers here as well:<br /><b>1 ...
