Yace was quite a decent (*) engine (**), book making was similar to Crafty; and a regarding a tiny few points
imo a little bit better; once upon a -long time- ago i made it's opening book for a CSVN tourn
(and also was the operator) https://www.vrichey.de/leiden/
Nostalgia maybe :mrgreen:
(*) in the sense of a moderately strong, quite solid program; and mr DB was a decent guy btw
(in the other -sociological- sense); presumably still the same; wisely, he apparently abandoned
computer chess 8-)
(**) nowadays when people looking for winboard engines for whatever reasons, it's still an
interesting engine (going to include again in my chessgambiteer package (with which i
produced these awesome brilliancy&beauty games :lol:

:D next November a new Csvn tournament ? apparently it's a programmers tourn
https://www.csvn.nl/index.php/verenigin ... 6-november

cool anyway, if -honest- derivatives are allowed - as it was years ago- i can participate with the awesome
now almost revived Djengis winboard engine (based on mscp1.x by the late kervinck but with more stuff )
but still only -limited to- Elo 1700 or so in default mode (*) Nevertheless now with an (book) author
modestly but also truely being the world's biggest gambit inventor (after a certain well respected
nr 2 mr Zilbermints in the NY Manhattan chess club ) will there be beer as usual ? ah well it's anyway
approx 20 mins from my location with a cab; can have a look anyway :D
once i can transform the engine to using my polyglot gambit book it may even be more awesome.
As for playing strength (cq engine originality), i don't care, will not steal/copy (more) code,
and too old now to start from 'scratch', something which nobody does completely anyway.

(*) deliberately; my engine should play in human style; in default settings;
accidentally, it may play stronger (later) if not handicapped, but then not aiming
anyway for superGM strength (except maybe surpassing Carlsen or so
when disabling some handicap settings )

Last year there was plenty beer. It is still (again) in Leids' denksportcentrum which has beer, tosti's and expensive coffee.
I'll participate with Dog on a microcontroller, about 1951 elo.

This is certainly not true if we go back in time some.

At its peak Yace was probably the closest amateur engine to the then still ruling current pros. It scored two 2nd places in major high-level tournaments at slow time control at a time where this was still deemed very relevant.

It certainly feels this way if you pit it against modern engines though. This was at pre we-prune-like-mad and NNUE times.

So Yace gets punished in a double way. It can't search deep enough AND the eval feels sub-par now.

I wonder whether humans have improved in the mean-time due to the engines. Yace was probably low GM Level in 2001. It looks very silly if you match it against modern engines. Would a modern GM be able to deal with the likes of Yace? Or are humans just hopeless?
