Speediest for selective found in 11 moves at 1.4 sec. The most probable that my selective can't find nothing below this. At least, I disconnected more deep selective when I found that it take more that 1 min. >Cheers, Tim. > >Analysis, GLC 2.13-pr1, 24MB hash, 920MHz Duron: > >>anal > Game stage: Opening > Current eval: 18.38 > Ply Time Score Nodes Principal Variation > 3 0.01 29.64 5045 Nfxg6+ Qxg6 Nxg6+ Nxg6 Rxh7+ Bxh7 > 3 0.02 29.64 5184 Nfxg6+ Qxg6 Nxg6+ Nxg6 Rxh7+ Bxh7 > 4 0.05 29.69 15017 Nfxg6+ Qxg6 Nxg6+ Nxg6 Rxh7+ Bxh7 Qxd8+ Bg8 > 4 0.09 29.69 28281 Nfxg6+ Qxg6 Nxg6+ Nxg6 Rxh7+ Bxh7 Qxd8+ Bg8 > 5 0.53 -- 279496 Nfxg6+ (a=29.19 b=30.19 e=29.19) > 5 0.54 ++ 282935 Nfxg6+ (a=-321.00 b=29.20 e=29.20) > 5 0.55 29.22 288504 Nfxg6+ Qxg6 Nxg6+ Nxg6 Bgxf6 Be3+ Qfxe3 Bxd5 > 5 0.55 29.22 288589 Nfxg6+ Qxg6 Nxg6+ Nxg6 Bgxf6 Be3+ Qfxe3 Bxd5 > 6 0.56 ++ 292411 Nfxg6+ (a=28.72 b=29.72 e=29.72) > 6 0.76 33.19 417592 Nfxg6+ Qxg6 Nxg6+ Nxg6 Bgxf6 Nxf6 Qxf6 Bf8 Rxh7+ > Bxh7 Qfxd8 > 6 1.28 33.19 793375 Nfxg6+ Qxg6 Nxg6+ Nxg6 Bgxf6 Nxf6 Qxf6 Bf8 Rxh7+ > Bxh7 Qfxd8 > 7 1.32 ++ 805216 Nfxg6+ (a=32.69 b=33.69 e=33.69) > 7 2.43 36.34 1614187 Nfxg6+ Nxg6 Nxf7+ Nxf7 Bgxf6 Nxf6 Qxf6 Bd4 Qxg6 Nh6 > Qge8 > 7 5.08 36.34 3523071 Nfxg6+ Nxg6 Nxf7+ Nxf7 Bgxf6 Nxf6 Qxf6 Bd4 Qxg6 Nh6 > Qge8 > 8 5.21 ++ 3602654 Nfxg6+ (a=35.84 b=36.84 e=36.84) > 8 10.51 320.83 7709270 Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qcd5+ Kh8 > Rxh7+ Nxh7 Qg8+ Kxg8 Bxh7+ Kh8 Qxf8# <ht> > 8 16.66 320.83 13745k Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qcd5+ Kh8 > Rxh7+ Nxh7 Qg8+ Kxg8 Bxh7+ Kh8 Qxf8# <ht> > 9 20.73 320.85 18003k Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qee8 Nxc6 > <ht> > 9 33.64 320.85 31079k Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qee8 Nxc6 > <ht> > 10 46.11 320.85 44792k Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qee8 Nxc6 > Bxh7+ Kh8 Qxf8+ Ng8 Qxg8# <ht> > 10 1:33 320.85 95317k Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qee8 Nxc6 > Bxh7+ Kh8 Qxf8+ Ng8 Qxg8# <ht> > 11 2:07 320.85 131947k Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qee8 Nxc6 > Bxh7+ Kh8 Qxf8+ Ng8 Qxg8# <ht> > 11 5:39 320.85 362972k Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qee8 Nxc6 > Bxh7+ Kh8 Qxf8+ Ng8 Qxg8# <ht> > 12 7:12 320.85 465267k Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qee8 Nxc6 > Bxh7+ Kh8 Qxf8+ Ng8 Qxg8# <ht> > 12 15:05 320.85 979669k Nfxg6+ Nxg6 Nxg6+ Qxg6 Qxg8+ Kxg8 Bxg6 Bf8 Qee8 Nxc6 > Bxh7+ Kh8 Qxf8+ Ng8 Qxg8# <ht> > 13 15:35 0/77 Nfxg6+ >exit > local: t=15:41 nps=1083291.8 n=1020411074 (f=240107661 q=780303413) > total: t=15:41 nps=1083291.8 n=1020411074 draws=91764 This is where I am very curious to ask you one question. Is this just like I read it? Your program see 1083291 nodes/second? It is too far from what I can expect from my NPS. I don't know exactly speed for this position for my mate solver, since I don't install it but I can guess what it can be after second part of my program. There I have counter.
