{White to move, black just played Rxf1+ }
{Second best is Kxf1 (0.00) best is Bxf1 (0.92) }
{This is sort of an anti-tactic. }
{The main point is not to play Qxf1?, because then black has Qc5+, winning the knight. }
1.Bxf1 c5 {If Bxa2, exploiting the discovered attack, then Ng6 is strong: }
(1... Bxa2
2. Ng6 Qf7
3. Rxa2 Qxg6 {Qxa2 isn't good because then d4 threatens Bc4+, }
{which not only forks King and Queen, but also leads to mate. }
