I just discovered that Ryan made the new Beta 4bx of Gambit Fruit handle Quiescense checks of more than 2 ply deep! Great, that was not possible in old version! Eelco Some more testing of Ferret-Gandalf: >But this is a very speculative testposition, as White is lost no matter what if >Black plays well. Haven't tried it with Rybka yet! Rybka takes 11 minutes, good if not blindingly fast. Noticeable are the big negative evals that show that Rybka thinks White is in trouble, which is very accurate.

Gambit Fruit Beta 4bx Chess Knowledge = 200 [From 100] Rebel Reductions [Default] Quiescense Check Plies = 1 [Default] History Treshold = 70 [Default] (200 Mb HT) This looks a bit faster, 4 min 5 seconds, although 1..Ra7 not found right away But big improvement over 1 hour 22 minutes of Beta 4b! One caveat: when changing an option, CP GUI had to be closed and started up again with Gambit Fruit 4bx for any change in settings to take effect. The same applies if you want to change the opening book (.bin enginebook). Probably the same for other GUIs? 00:00:00.0 -0,85 1 3 Bxb4 Rxb4 00:00:00.0 -0,95 2 392 Bxb4 Rxb4 Qd3 00:00:00.0 0,62 3 1628 Bxb4 Nd4 Qe1 Nxf3+ gxf3 00:00:00.0 0,39 4 2288 Bxb4 Nd4 Qe1 Nxf3+ gxf3 a3 00:00:00.0 -0,44 5 7031 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 00:00:00.0 -0,44 6 14411 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 00:00:00.1 -0,76 7 30509 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 00:00:00.1 -1,06 8 62426 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 c5 dxc5 00:00:00.2 -1,06 9 121964 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 c5 dxc5 00:00:00.4 -1,41 10 278000 Bxb4 Nd4 Qe1 Qb2 Rf6 Qxb4 Qxb4 Rxb4 Bd3 Rb3 Bf1 Rd8 00:00:00.8 -1,48 11 599874 Bxb4 Nd4 Qe1 Qb2 Bxd6 Qxb1 Qf1 Qxf1+ Nxf1 Nxf3+ gxf3 Rb3 c5 a3 c6 Rxf3 00:00:01.7 -1,67 12 1204937 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 Rc3 Rc8 c5 Rxc5 Rxc5 dxc5 Bd3 00:00:03.6 -1,58 13 2617587 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 Rc3 Rc8 Bd3 a3 Rc2 Qb1 00:00:07.4 -2,05 14 5535694 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 c5 Rc4 Bd1 Rxc5 Rg3 Rc1 Qf1 00:00:21.6 -2,73 15 15962910 Bxb4 Nd4 Qe1 Qb2 Bxd6 Qxb1 Qxb1 Rxb1+ Kh2 a3 Be5 Nxf3+ gxf3 Rc8 Kg3 a2 d6 a1Q Bxa1 Rxa1 d7 Rd8 Nc2 Rg1+ Kh2 00:00:55.4 -2,83 16 40068026 Bxb4 Nd4 Qe1 Qb2 Bxd6 Qxb1 Qxb1 Rxb1+ Kh2 a3 Be5 Nxf3+ gxf3 Rc1 Kg3 a2 d6 Ra7 Kf4 Kf8 Bd4 a1Q Bxa1 Rcxa1 00:04:05.7 -2,82 16 168426926 Nf5 Qxa3 Nh6+ Kg7 Rxf7+ Kxh6 Qf3 Qc1+ Kh2 Rh8 Qf6 Rh7 e5 Rg8 Qg5+ Qxg5 hxg5+ Kxg5 Rxh7 Nd2 Rb7 Nxb1 Rxb4 00:10:48.7 -2,69 17 441636836 Nf5 Ra7 Nh6+ Kg7 Nf5+ gxf5 Rg3+ Kf8 exf5 Rab7 f6 Qxf6 Bh7 Qa1 Qxa1 Nxa1 Bb2 Nac2 Bf6 Ke8 Bf5 00:35:14.4 -2,16 18 1436682289 Nf5 Ra7 Nh6+ Kg7 Nf5+ Kf8 Nxd6 Qxa3 e5 Qa1 Nb5 Re7 e6 Kg8 Rg3 Nxd5 exf7+ Rxf7 Rxg6+ Kf8 Rg5 Qb2 Rxd5 Qxf2+ Kh1 Qxh4+ Kg1 00:49:31.8 -2,23 19 2023464098 Nf5 Ra7 Nh6+ Kg7 Nf5+ Kf8 Nxd6 Qxa3 e5 Qa1 Nb5 Re7 e6 Kg7 exf7 Rxf7 Rxf7+ Kxf7 d6 Kg7 d7 Rd8 f4 Qf6 Qe1 Qb6+ Kh1 01:58:50.2 -2,32 20 553140923 Nf5 Ra7 Nh6+ Kg7 Nf5+ Kf8 Nxd6 Qxa3 e5 Qa1 Nb5 Re7 e6 Kg7 exf7 Rxf7 Rxf7+ Kxf7 Qf3+ Kg7 Qe4 Qf6 Qe3 Kg8 Qg3 Rb6 Be4 Qa1+ Kh2 04:29:58.9 -2,81 21 2383183077 Nf5 Ra7 Nh6+ Kg7 Nf5+ Kf8 Nxd6 Qxa3 e5 Qa1 Nb5 Rxb5 cxb5 Nd4 Rf4 Ne2+ Qxe2 Nxd5 Rc4 Qxb1+ Kh2 a3 e6 a2 Rc8+ Kg7 exf7 Rxf7 Qe5+ Rf6 Ra8
