On my P233 with a 4MB hash table, Insomniac's score drops to 0 after 30 seconds.

Perhaps these are positions where Vincent's beloved checks in qsearch would help? :) Depth Score Time Nodes PV 1 51 0 50 Rxb1 Rxb1 2 51 50 270 Rxb1 Rxb1 3 61 50 743 Rxb1 Rxb1 f4 4 62 50 4279 Rxb1 Rxb1 f4 Be4 5> 92 160 11376 Rxg7+ 5 128 220 16249 Rxg7+ Kb6 Rb7+ Ka5 b6+ Ka4 a7 Bg3+ Kxg3 6 138 1040 95989 Rxg7+ Bd7 Rgxd7+ Ka8 Rd8+ Bb8 R5d7 Rxb5 Bxb5 Qxb5 7 119 1590 147646 Rxg7+ Bd7 Rgxd7+ Ka8 Rd8+ Bb8 R5d7 Qh1 a7 Qh2+ Ke1 8 51 8340 823729 Rxg7+ Kb6 Rb7+ Ka5 Rxe5 Qh1 Rxf5 Qh2+ Ke3 Qg1+ Kd2 Qd4+ Bd3 Rb2+ Kc1 Qxd3 Kxb2 Qxf5 9 44 13510 1357694 Rxg7+ Kb6 Rb7+ Ka5 b6+ Ka4 Rxe5 Bc8 Re8 Bxb7 axb7 Rxb6 Ra8+ Kb3 b8=Q Rxb8 Rxb8+ 10 19 29600 3007365 Rxg7+ Kb6 Rb7+ Ka5 b6+ Ka4 Rxe5 Qh1 Rxf5 Qh2+ Ke1 Qg1+ Kd2 Qd4+ Bd3 Rb2+ Kc1 Qc3+ Kd1 Qxd3+ 11> 27 101440 9695956 Rxb1 Rxb1 f4 Be6 Rd8 Bxf4 Re8 Bxh3 Re7+ Kb6 Rb7+ Kc5 Rxg7 11 27 111110 10848841 Rxb1 Rxb1 f4 Be6 Rd8 Bxf4 Re8 Bxh3 Re7+ Kb6 Rb7+ Kc5 Rxg7 Extensions: 695609 check, 1421 mate, 25474 recapture.
