I have released a new version of my chess engine, Tony's Chess version 0.03. It is available for download at http://tonyschess.x10host.com/. In my testing, it has a rating of approximately 1900 on the CCRL scale. Most of the strength changes have come from use of a more modern compiler, a faster move generator (mostly due to incremental hash update), better time handling, eval tapering, and more accurate weighting of evaluation parameters. Enjoy!

Thank you Tony. I'm going to test it as soon as I can (soon...).

Raven 0.50: https://github.com/sgriffin53/raven/releases

It looks like it has become 64-bit as well, although that is not stated explicitly.

Hello,
I have a new version of Googleplex Starthinker :D
https://gitlab.com/tsoj/Googleplex_Star ... -/tags/1.6
(version 1.5 was a failed development version)
There are no new big features, I rather removed a lot and tweaked stuff.
Some changes are:
- removed aspiration window
- removed transposition table lookup from quiesce
- removed internal iterative deepening
- removed "hashfull" calculation for UCI info
- changed evaluation parameters and added some minor features
- changed futility pruning conditions
- better time management
- play losing captures after killer moves
- better late move reduction conditions
- better ratio between always-replace and selective-replace in transposition table
- changed PVS conditions
- fixed some bugs

Elo improvement compared to version 1.4 in 1min/40moves games is somewhere between 50 and 150.
