my point was that comparing with ancient released versions is silly. Especially
at low level the strength varies a lot.

No clue, if I see larsenVB and tscp playing in 3rd division I wonder what Celes
does in 4th :)

I don't have ant installed on my computer.

'clearly better' is a bit harsch I suppose. I valued (a stable) ant at ~2300,
while baron is ~2200. It's been a while since I tested with Baron though.

It's so amazing Kasparov still plays 1.e4 after all those games he lost with it

Openings have so many variations that you could still opt to play them, even if
you lose a couple of games with it. If you look at the games Ant played you'll
notice it doesn't pick the 'best' move in some positions. Celes went down to
-0.05 after 15.c3 after which I considered the opening to be going well for

See previous comment.

That's a healthy idea :)
I have a much faster version of Celes (speedup 20-25%) but I'm not sure if it
runs stable. Perhaps I'll play with it next week.

As I pointed out to Shark, what works for other people may not work for you.

hmmm, you'll still get alot of repetitions that way.
