He can play Kxb7 instead of Qxb7, then if the R or B takes on c6, the Q takes back, then the remaining piece takes and he has given up a queen and 2 pawns for 2 rooks and a bishop. You would have his K out in the open though which is a dangerous place to be
Instead of 3.Rc4, how about 3.Qa6+? That looks like it should lead to a mating net. 3..Kb8 4.Rb1+ Qb6 5.Rxb6+ Kc7 6.Rb7+ Kd6 7.Qc4 * 8.Qd5#
I think best shot is probably to sac the bishop on c6 followed by Qa6+ . looks like it could lead to a king hunt as well.
I just played a game with a seemingly strong combonation. I wonder if I was right, or I blundered....due to the lack of quality in this game i'll only post the combonation. Plz comment.
