This release is mainly a bugfix of release 2.2, it also contains a LMR tweak which will add around 10 elo.

The bug: When the search was pondering or in infinite analysis mode, sometimes the search would return a “bestmove” prematurely. This is not correct and some GUI’s can not cope with this bug and crash (for instance the Shredder GUI).

A big thanks to Gerhard of the cegt team for noticing the bug and helping to find the cause! and a big thanks to all who take interest in rofChade.

After a longer period of little activity I got a boost to develop a new rofChade version after trying a retune with the “lichess-good” set as discussed in the topic about Texel tuning viewtopic.php?f=7&t=71469#p807692, I got an elo increase of around 30 elo! So thanks Fabian, Jon and Vivien for discussing the topic and making the position set available!

Version 2.2 also contains multiple changes which resulted in an estimated elo gain of 50/70 elo single threaded. Because of some changes to hash table and multi threading the elo gain with multiple threads is hopefully a bit higher.

rofChade 2.2 can be downloaded under the tab “Download”. Under the tab “Releases” the version changes are defined.

Thanks to everybody who takes interest in rofChade!
