Hi Pedro,
You are partly right, I have installed a lot of <2300 engines, 1/4th of them seem to have some kind of major bugs. As evidenced in Tony's no play list.
Some of them lose on time, some of them don't play the predifined opening positions/only play with the book, some lose on time when given check, a lot of them unupdated older ones etc These type of bugs are rare in engines >2300.
You are also right in your estimation that there are still 50% of authors active in comp chess. But I'm getting the impression that there are more authors who have <2300 engine than those who have >2300, That's just me.
Anyway, I'd be interested in making a poll about it. I just can't decide what to do when it comes to comp chess testing and tournament creating, I feel any kind of tournament set up is just too good
Regards,
Swami
