I think that the computer after searching a lot of nodes may getthe right moves even without understanding of the position. I think that the first moves are critical and the position is very tactical so it may be interesting to look at the lines that already posted and to ask computer for next best to see if there are alternatives I think that computer-computer games are good for positions that are more quiet and for tactical positions a long analysis of lines is better and a long analysis seems to prove that h3 is losing based on another post. The line that is missing after h3 seems to be h3 Qa1+ Kh2 Qe1 because Nf1 was mainly analzed but even here it seems that a long analysis can prove that white is losing Here is some analysis by Fritz8 Deep_Junior(C) - Kasparov_1/2 [D]2b2rk1/Rp5p/3p2pQ/2nP4/2P1pp2/7P/P1RN1PPK/4q3 w - - 0 1 Analysis by Fritz 8: 28.Ra8! µ (-0.97) Depth: 6/25 00:00:00 88kN 28.Ra8! µ (-0.81) Depth: 6/25 00:00:00 89kN 28.Ra8! ³ (-0.50) Depth: 6/25 00:00:00 91kN 28.Ra8 Nd3 ³ (-0.28) Depth: 6/25 00:00:00 99kN 28.Ra8-- ³ (-0.56) Depth: 7/19 00:00:00 108kN 28.Ra8 Nd3 29.Qxf8+ Kxf8 µ (-0.97) Depth: 7/21 00:00:00 130kN 28.a3! µ (-0.94) Depth: 7/21 00:00:00 158kN 28.a3! µ (-0.78) Depth: 7/21 00:00:01 164kN 28.a3! ³ (-0.47) Depth: 7/23 00:00:01 182kN 28.a3-- µ (-0.75) Depth: 8/19 00:00:01 237kN 28.a3 Nd3 29.Nxe4 Qxe4 30.Rd2 f3 31.gxf3 Rxf3 32.Ra8 Qxc4 -+ (-2.16) Depth: 8/23 00:00:01 337kN 28.a4! -+ (-2.12) Depth: 8/23 00:00:02 373kN 28.a4! -+ (-1.97) Depth: 8/23 00:00:02 379kN 28.a4! -+ (-1.66) Depth: 8/23 00:00:02 387kN 28.a4! µ (-1.03) Depth: 8/23 00:00:02 457kN 28.Ra8! µ (-1.00) Depth: 8/23 00:00:02 547kN 28.Ra8 Nd3 29.Nb3 Nxf2 30.Rc1 Qe3 31.Qh4 Nd3 32.Rf1 µ (-0.94) Depth: 8/23 00:00:02 561kN 28.Nb3! µ (-0.91) Depth: 8/23 00:00:03 620kN 28.Nb3 e3 29.fxe3 Qg3+ 30.Kh1 µ (-0.87) Depth: 8/23 00:00:03 656kN 28.Nb3-- µ (-1.16) Depth: 9/22 00:00:03 730kN 28.Nb3 e3 29.fxe3 µ (-1.16) Depth: 9/34 00:00:04 1041kN 28.Ra8! µ (-1.12) Depth: 9/34 00:00:04 1131kN 28.Ra8! µ (-0.97) Depth: 9/34 00:00:04 1181kN 28.Ra8 Nd3 29.Nb3 Nxf2 30.Rc1 Qe3 31.Qh4 Nd3 32.Rf1 µ (-0.94) Depth: 9/34 00:00:05 1248kN 28.Ra8 Nd3 29.Nb3 Nxf2 30.Rc1 µ (-1.00) Depth: 10/28 00:00:07 1755kN 28.Ra8 Nd3 29.Nb3 Nxf2 30.Rc1 Qe3 31.Qg5 Nd3 32.Rf1 Qe2 33.Rb1 µ (-1.00) Depth: 11/32 00:00:12 3616kN 28.Ra8 Nd3 29.Nb3 Nxf2 30.Rc1 Qe3 31.Qh4 Nd3 32.Rf1 Qe2 33.Kg1 Re8 34.Rxf4 Nxf4 µ (-0.84) Depth: 12/34 00:00:21 6669kN 28.Ra8 Nd3 29.Nb3 Nxf2 30.Rc1 Qe3 31.Qh4 Nd3 32.Rf1 Qe2 33.Kg1 Re8 34.Rxf4 µ (-0.84) Depth: 13/34 00:00:46 16161kN 28.Ra8 Nd3 29.Nb3 Nxf2 30.Rc1 Qe3 31.Qg5 Nd3 32.Rf1 Qe2 33.Kg1 Re8 34.Qf6 µ (-1.09) Depth: 14/37 00:01:27 32605kN 28.Ra8-- µ (-1.37) Depth: 15/40 00:04:20 102996kN 28.Ra8 Nd3 29.Nb3 f3 30.gxf3 Qf1 31.Qg5 Ne1 32.Nd4 Nxc2 33.Nxc2 Qxf2+ 34.Qg2 Qxg2+ 35.Kxg2 -+ (-2.22) Depth: 15/45 00:07:00 168145kN 28.Ra3! -+ (-2.19) Depth: 15/45 00:08:39 209939kN 28.Ra3! -+ (-2.03) Depth: 15/45 00:09:18 226612kN 28.Ra3! -+ (-1.72) Depth: 15/45 00:10:10 248461kN 28.Ra3 Nd3 29.Nxe4 Qxe4 30.f3 Qd4 31.Rd2 Bf5 32.Rb3 Rb8 33.Re2 Ne5 34.Reb2 -+ (-1.41) Depth: 15/45 00:11:59 293224kN (Blass, Tel-Aviv 30.01.2003) Uri
