It is clear to many players that when your pieces are passive and you cannot castle 2 pawns advantage is not important. I believe that it is also clear to some programs like Chess system tal I do not have chess system tal but I read that it often has big positional scores. It is clear to many players(even with no correspondence rating) that if the score is positive and going down you should suspect that something is wrong with the evaluation. I am very surprised to read that it was not clear to 2400 rating player. <snipped> >Fritz and all his brothers-engines evaluated the possible position as >around +- 2.5 not in my favour. They did not give around 2.5 pawns for your opponent. I checked the position with Fritz5 for a short time and it gave a positive score for your opponent but not more than 1 pawn. I do not have Fritz532 but I do not think that the scores are clearly different <snipped> >Canada- Sirota >1.d4-Nf6 2.c4-g6 3.Nc3-Bg7 4.e4-d6 5.f3-0-0 6.Bg5-a6 7.Qd2-c5 8.d5-b5 9.cxb Qa5 >10.a4-Nbd7 11.Nge2-Nb6 12.Nc1-axb 13.Bxb5-Ba6 14.N1a2-Bxb5 15.axb- Nh5 >16.Rb1-Bd4 17.b3 (reccomandation of Ivanchuk.In his analises in Chess Informator >Ivanchuk gives absolutely silly lines.

Somethink MUST be found !) - f5 I gave Junior5.9 to look at this position and it see negative score for white with Bxe7 after less than 40 minutes on slow p200MMX Junior5.9 found 18.b4 after less than an hour(evaluation +0.02 for white) I believe that it can find also that 18.b4 is losing if I give it more time. <snipped> >18.Bxe7 ( I played this game >6 months ago, so I forget many lines.
