nmr: NMR smooth scaling option
pawn hash size was 64 mb.
common hash size was 128 mb.
firebird 1.1 with nmr off(new default) had best results.
IvanHoe-Beta-999964-Beta had good results. tuning that may pruduce better engine.
Each engine had 2 cores.
GUI was Arena.
Considerable advantage of IvanHoe is that it is open source but firebird isn't open source.
