But is a3 really very necessary when White can just answer b3? Shredder would play 19..Rfc8 first and thinks Black is well ahead: [D]r1r3k1/2qnbppp/3p4/3Pp1P1/pp2N3/3QBP2/PPP4P/1K1R2R1 w - - 17/47 17:07 +0.82 19...Tfc8 20.h4 b3 21.cxb3 axb3 22.Dxb3 Tcb8 23.Dc3 Db7 24.Dc2 Ta3 25.Pc3 (224.222.020) 218 beste zet: Tf8-c8 tijd: 17:31.907 min n/s: 218.088 CPU 48.5% n/s(1CPU): 449.665 nodes: 229.388.789 (This line looks more threatening IMO against White's kingposition than with first a3, b3 as Fruit would play it) Instead of h4, a 1300 player like me would consider 20.Rc1 and now Shredder seems a bit confused: 15/26 0:04 +0.87 20...Ta5 21.Tgd1 Db7 22.h4 Tb5 23.Ka1 a3 24.b3 f5 25.gxf6 Pxf6 26.Pxf6+ Lxf6 27.Kb1 Tc3 (1.184.453) 243 16/41 1:22 +0.62-- 20...Ta5 21.Tgd1 (18.700.053) 226 16/41 2:08 +0.15 20...Ta5 21.c4 Dd8 22.h4 (28.704.792) 224 16/41 2:32 +0.16++ 20...Pf8 (34.033.187) 223 16/41 3:14 +0.49 20...Pf8 21.h4 Db7 22.f4 Ta5 (43.167.307) 222 Black switching to the other wing with 20..Nf8 (P is Paard, Dutch for Knight, D is Dame, Queen, T is Toren, Rook) White gets time to play h4. This does not look so bad for White? But, with two open wings, the fight might go either way! Regards, Eelco [D]r1r3k1/2qnbppp/3p4/3Pp1P1/pp2N3/3QBP2/PPP4P/1KR3R1 b - -
