Thanks. Yes, this is an interesting tournament and I'll look forward to the
complete results. I'm starting to recognize that Fruit is a top engine now,
maybe the best, after using the Shredder 7-8-9 versions almost exclusively for
the last few years. Now I must seriously look at Fruit. I don't know about Fritz
9 yet.

I ran a quickie match between Fruit 2.2.1 and Shredder 9.1 and they are still
almost neck & neck after 100 games:

I may not play any more games in that match. It has already told me what I
wanted to know, that Fruit is a serious competitor now. Shredder came on strong
right at the end to almost catch up, possibly because of its learning
ability(?). I leveled the field somewhat by using the Shredder 9 book for both,
because I wanted to compare the calculating abilities mostly, not opening book
strengths.

You mention endgame strength, and in my opinion the Shredder engines (7-8-9) are
not good endgame players. I think the equivalent Fritz and some other engines
are better in the endgame. The Shredder 9 version has improved tablebase access
greatly, and it's the best, but still I consider it stupid when the endgame
approaches. I often have to experiment with other engines to find the best
endgame lines. From what I've seen so far, Fruit has better native endgame
savvy.
