Subject: rybka and fruit 2.2.1 badly disagree in this position

Author: Joseph Ciarrochi

In the following position, fruit and fruit derivatives (e.g., toga 1.1.) think
that black has a strong advantage


1) e4 d5, 2)exd5, qxd5 3) nc3 qa5; 4) d4, c6; 5) nf3, nf6 6) bd2, qb2

In contrast, Rybka  sees it as a small advantage to equal.

Why this big difference? It is probably safe to assume that rbyka is more
accurate (given it is the better engine, and IM martin recommends this line). If
so, why would you say fruit is misevaluating?


A second question: As the comps get better and better, should we expect
evaluations to converge? Will we get to the point where programs more or less
agree on the evaluation of a position (adjusting maybe +-.20 for engine
personality)
