I have looked at hard 43 IQ test postions and found, that about 20 of them are doubtful (positions here: http://www.horizonchess.com/jim/). With doubtful I mean, that with modest PC and four top programs I haven't found "bm" correct. Of course I can be wrong, but definitely not in all positions... So all these are doubtful: 1023,1024,1027,1033,1044,1057,1111,1121,1150,1158, 1162,1187,1191,1198,1226,1248,1253,1270,1274,1290. I am too lazy to write down all my findins, but here some sample positions. 1044 [D]2rq4/p2n1pk1/4b1r1/2pNp1p1/BpP1Pn2/3PQPP1/PR6/1R2B1K1 b - - bm Qh8; but after -Qh8 Bxd7! black can't win? 1121 [D]7r/8/3p1p1r/p1kP2p1/Pp2P1P1/1PpR3P/5R1K/8 b - - bm Rxh3+; after forced -Rxh3+ Rxh3 Rxh3+ Kxh3 Kd4 it's only draw? 1162 [D]5r2/p5kp/1p3rp1/2pPpp2/2n3q1/P1PQPRB1/5RPP/6K1 w - - bm Bf4; Bf4 e4! and white hasn't good continuation? 1290 [D]r4rk1/4ppbp/1q2bnp1/n1p4P/4P1P1/2NBBP2/PP1Q4/1K1R2NR b - - bm Bxa2+; according to Tiger also -Rhb8 wins (=different move order)?
