Any idea of strength?

3.0.0.0 version it's probably a little over 2,000 Elo points (CCRL Blitz). Here is my test for 2.0.0.5 version:

Smallbrain 5.0
https://github.com/Disservin/Smallbrain

From release readme

Code: Select all

A lot has happened since version 4.0!
Smallbrain now supports multithreading. Yay!

Early Lazy SMP Tests show a gain of ~100 elo using 4 Threads vs 1 Thread

ELO   | 127.64 +- 17.03 (95%)
CONF  | 5.0+0.05s Threads=4 Hash=64MB
GAMES | N: 1035 W: 495 L: 131 D: 409

It also features a bunch for other new stuff and is in total 200 elo stronger (not counting smp strength) than 4.0!
The biggest elo gainer was fixing how I use TT moves during move ordering.
Another big elo gain was also a big search tune, tuning 11 parameteres.
Elo test against v4.0

ELO   | 211.87 +- 19.73 (95%)
CONF  | 40.0+0.40s Threads=1 Hash=64MB
GAMES | N: 1000 W: 616 L: 72 D: 312
