Hi, Here's a couple more tough ones. Shredder doesn't see them. I'm not picking on Shredder. It's just the only commercial I have. Out of the 360 positions, Shredder misses only 48 of them after two minutes each. [D] r1b3k1/1pp1q1p1/1r5p/2nPpp2/p1P1p2P/2N1P3/PPQRBPP1/2K4R b - - This is Movshovich-Tribushevsky, Moscow 1956 r1b3k1/1pp1q1p1/1r5p/2nPpp2/p1P1p2P/2N1P3/PPQRBPP1/2K4R b - - bm Nb3+; id "IQ.1019"; 1... Nb3+ 2. axb3 axb3 3. Qd1 ( 3. Qb1 Rba6 ) 3... Ra1+ 4. Nb1 Qb4 5. d6 Qa4 6. d7 Rxb1+ (0-1) [D] r1r2k2/1q1n1p2/3PpPp1/4P2p/pbpN3R/2N3K1/1P2Q2P/3R4 w - - This is Sanakoyev-Zagorovsky, Voronezh 1972 r1r2k2/1q1n1p2/3PpPp1/4P2p/pbpN3R/2N3K1/1P2Q2P/3R4 w - - bm Rxh5; id "IQ.1022"; 1. Rxh5 gxh5 2. Qxh5 Ke8 3. Nxe6 Nf8 4. d7+ Nxd7 5. Qh8+ Bf8 6. Qxf8+ Nxf8 7. Ng7# Really pretty. 1 sec -> 185/360 2 sec -> 219/360 3 sec -> 231/360 4 sec -> 244/360 5 sec -> 249/360 6 sec -> 256/360 7 sec -> 261/360 8 sec -> 266/360 9 sec -> 269/360 10 sec -> 270/360 11 sec -> 274/360 12 sec -> 276/360 13 sec -> 278/360 14 sec -> 281/360 15 sec -> 282/360 20 sec -> 285/360 25 sec -> 290/360 30 sec -> 291/360 40 sec -> 295/360 50 sec -> 300/360 60 sec -> 302/360 90 sec -> 305/360 120 sec -> 312/360 Test range (1564 to 2764) IQ elo = 1564 + (% score x 12) IQ elo at 2 minutes = 2604 (86.67%) IQ elo at 10 sec = 2464 (75.%) Shredder on Cel 1.3Ghz/256 32MB hash Still some buggy positions though. Cheers, Jim
