On a PIII-600, it finds all of them. It also finds all of them in less than one second except for: BWTC.544 (0:12) BWTC.548 (1:08) BWTC.632 (0:03) BWTC.702 (0:14 -- but with Rf5+ and Mate in 9. Is that better than Qh5+?) BWTC.911 (0:05 -- but with Qf6 and Mate in 8. Is that better than Rf8+?) BWTC.958 (less than one second, but Qd7 is also Mate in 2) BWTC.960 (less than one second, but Rxa5 is also Mate in 2) jm
