A favourite testposition: Fruitbat 0.1 Experimental in Ferret-Gandalf position goes to Nf5 or e5 fairly quickly where standard Fruit plays Bxb4 a lot longer. These moves don't change the bad position White is in but have some fighting value. The line after Nf5 looks a bit better than e5 dxe5 Bxb4 to my taste [D]rr4k1/5p2/3p2p1/3P3p/pnP1P2P/Bn2NR2/5PP1/qB1Q2K1 w - - 1 1 00:00:00.0 -0,91 1 3 Bxb4 Rxb4 00:00:00.0 -1,21 2 401 Bxb4 Rxb4 Qd3 00:00:00.0 0,01 3 1752 Bxb4 Nd4 Qe1 Nxf3+ gxf3 00:00:00.0 -0,13 4 2792 Bxb4 Nd4 Qe1 Nxf3+ gxf3 a3 00:00:00.0 -0,58 5 6285 Bxb4 Nd4 Qe1 Nxf3+ gxf3 Qb2 Nc2 00:00:00.1 -0,73 6 13808 Bxb4 Nd4 Qe1 Nxf3+ gxf3 Qb2 Nc2 a3 00:00:00.1 -0,90 7 32592 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 00:00:00.1 -0,90 8 67472 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 00:00:00.2 -1,14 9 138787 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 c5 00:00:00.5 -1,11 10 315628 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 c5 dxc5 00:00:00.9 -1,60 11 608072 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 Rc3 a3 e5 00:00:02.0 -1,79 12 1404787 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 c5 Rc4 Bd3 Rxc5 00:00:04.4 -2,09 13 3204405 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 c5 Rc4 Bd1 Rxc5 Be2 00:00:09.3 -2,24 14 6843245 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 c5 Rc4 Bd1 Rxc5 Be2 a3 00:00:24.7 -2,21 15 17890858 Bxb4 Nd4 Qe1 Qb2 Nc2 Nxc2 Bxc2 Rxb4 c5 Rc4 Bd1 Rxc5 Rg3 Rc1 Rd3 00:01:51.9 -3,35 16 80494739 Bxb4 Nd4 Qe1 a3 Kh2 Nxf3+ gxf3 Qe5+ Kg2 a2 Bxa2 Rxa2 Nd1 Ra1 Bc3 Rxd1 Bxe5 Rxe1 Bxd6 Rb2 c5 00:03:44.1 -2,87 16 159456054 e5 dxe5 Bxb4 Nd4 Qe1 Nxf3+ gxf3 Qb2 Nc2 a3 Bxa3 Qxb1 Qxb1 Rxb1+ Kg2 Ra4 c5 Rc4 Ne3 Rxh4 00:07:41.8 -2,76 17 323265043 e5 dxe5 Bxb4 Nd4 Qe1 Nxf3+ gxf3 Qb2 Nc2 a3 Bxa3 Qxb1 Qxb1 Rxb1+ Kg2 Ra4 Bd6 f6 Ne3 Ra2 00:16:32.0 -2,24 17 689266726 Nf5 Ra7 Nh6+ Kg7 Nf5+ gxf5 Rxf5 Qxa3 Qf3 Kf8 Qxh5 Qc1+ Kh2 Rab7 Qh8+ Ke7 Qf6+ Kd7 Qxf7+ Kd8 Qf8+ Kc7 Rf7+ Kb6 Qxd6+ Ka5 Rxb7 Rxb7 Qd8+ Rb6 Qa8+ Na6 I think this can be improved!
