I'd estimate this version to be about 200+ ELO better than the previous version.
- Added more basic endgame knowledge
- Added passed pawn evaluation (I think this added a lot of strength)
- Beefed up the evaluation routine to include basic terms such as mobility
- Fixed a nasty hash bug to do with mating positions
- Added one-reply to check extensions in the first ply of the quiescent search (help with some tactics – little impact on playing strength)
- Enabled hash cutoffs at PV nodes
- Nodes per second have dropped considerably due to the slower evaluation (now between 3 million and 5 million on my 2.8 GHz i7 notebook)
- A bazillion tweaks
