After Bxf7, it had this at depth=13:
               13->   2:12  -1.61   28. ... Rxf7 29. Qd5 Rf8 30. Bf4 h4
                                    31. Bd6 Qe8 32. c5 a4 33. c6 a3 34.
                                    Bxa3 Qe3+ 35. Kh2

It failed low at 14 to this:

               14     2:18     --   28. ... Rxf7
               14     3:01  -2.09   28. ... Rxf7 29. Qd5 Rf8 30. Bf4 Qe8 31.
                                    Bd6 Kh7 32. Qxh5+ Kg8 33. Qd5 Kh7 34. Bxf8
                                    Qe3+ 35. Kf1 Qc1+ 36. Kf2 Qxc2+ 37.
