[snip >That leaves only ECM.1134, ECM.1426 and ECM.1527 to be discussed. Any takers? > >Cheers. >pete Ok I start with ECM.1134: You are probably right in this: [D] 2r2rk1/1p1q1ppp/1p3n2/3p1N2/4n3/1N3Q2/PPP2PPP/R2R2K1 w - - bm Rxd5; id "ECM.1134"; It is no problem to find Rxd5 here - but is it really the best move ? 0:00:00.2 ( 7/13) 46412 0.19 1.Nbd4 Rfe8 2.Re1 Ra8 3.c3 (Mat=0,50=0) 0:00:00.3 ( 7/13) 84545 0.20 1.Rxd5 (Mat=100,50=0) 0:00:00.4 ( 7/15) 107045 0.69 1.Rxd5 Ng5 2.Rxd7 (Mat=1100,50=0) 0:00:00.6 ( 8/17) 184103 0.50 1.Rxd5 Qe8 2.Nd6 Nxd6 3.Rxd6 Rxc2 4.Rxb6 Qe2 (Mat=100,50=1) 0:00:01.6 ( 9/21) 414101 0.67 1.Rxd5 Ng5 2.Rxd7 0:00:03.5 (10/24) 1006908 0.45 1.Rxd5 Qe8 2.Nd6 Nxd6 3.Rxd6 Qe5 4.Rxb6 (Mat=200,50=0) 0:00:07.9 (11/27) 2212733 0.48 1.Rxd5 Qe8 2.Nd6 0:00:16.8 (12/28) 5107430 0.29 1.Rxd5 Qe8 2.Nd6 0:00:55.6 (12/33) 15894314 0.30 1.Nbd4 (Mat=0,50=1) 0:01:16.1 (12/33) 21718210 0.31 1.c3 (Mat=0,50=0) I tried with a few programs and my own brain: Rxd5, Nbd4 and also Ne3 to some extent all look very promising. My impression is that this testposition is still correct but I can't prove. If I had to play this position myself after looking at some of the lines I'd definitely prefer 1.Nbd4 :). Score after Nbd4: 13 4:14 0.73 1. ... g6 2. Nh6+ Kg7 3. Qe3 Rfe8 f3 Nc3 5. Nhf5+ Kg8 6. Qh6 Ne2+ 7. Kf1 Nh5 8. Re1 Nef4 9. g4 gxf5 10. gxh5 Score with Rxd5: 17 48:36 0.99 1. Rxd5 Qe8 2. Re1 Nxd5 3. Rxe4 Qc6 4. Nbd4 Qf6 5. Rg4 Ne7 6. Rxg7+ Kh8 7. Qh5 h6 8. Nxe7 Kxg7 9. Ndf5+ Kh7 10. Nxc8 Rxc8 So whites score is really different.
