Bb7, and White has no mate set against this move. So it seems that White must unpin the knight. It seems that either 1 Qb2 or 1 Qg7 would work, but 1 Qg7? (threat Qd7 mate) is refuted by 1 ... Sxe3!. So the key is <b>1 Qb2!</b> threatening Qb5 mate. Any move of the d5-knight defends, but White has answers in any case:<br /><br /><b>1 ... Sc7/Se7 2 Kg1</b> (waiting) <b>S~/Kd5 3 Qg2; 2 ... Sd5 3 Qb5; 2 ... Bb7 3 Qxb7</b><br /><b>1 ... Sb6/Sb4 2 Qg7</b> (waiting) <b>S~/Kd5 3 Qg2; 2 ... Sd5 3 Qd7; 2 ... Bb7 3 Qxb7</b><br /><b>1 ... Sxf4/Sf6/Sc3 2 Qb8</b> (threat Qxa8) <b>2 ...
