Comet B68 engine for endgame training

Tornado & Lightning by: Free Stock Photos Library; source: want today to give a shoutout to the Comet B68 chess engine. Might not be the best or perhaps not even among the top 100, but its peculiarities makes it an estimable companion for endgame training.

Nowadays top engines, will generally put an obstinate fight on endgame positions (no tablebases)  coming up with strong moves consistently. That's fine on one level, but that's also unhumanlike. Humans will try a variety of plausible moves and, if inspired, try to bamboozle or swindle.  The Comet engine , unlike the stronger engines that share too much DNA, will try approaches that may not be objectively the best, but that will still pose problems to the opponent, even more if he is mechanically playing. That is a plus for endgame training as it keeps the player on his toes. The most dangerous opponents are frequently those that are devious or who don't know better.

So far I've not been able to find another engine with similar characteristics, if you know of one,  please let us know.

According to Comet has an estimated rating of 2396 as of August 2014 and can be downloaded for free at
