Changes, as per readme.txt file
Lots of little changes! Change to IID, simplification. Slightly more aggressive LMR. Slighly less
agressive futility pruning. A number of minor speed optimisations. Tweak to move ordering when
in check. Slightly more agressive SEE pruning for quiet moves. Eval tweaks - greater malus for
low mobility for pieces. More aggressive king attack eval. Minor tweaks to pawn scoring etc.
Testing vs other versions of Francesca and other engines is showing an improvement of about 50 ELO. But I sometimes over-estimate improvements, so we will see
Cheers,
Tom
