1) I don't recommend the "Gambit suicidal" settings. Use the normal style or the
Gambit style for better results. Please note that if you are using CT15 inside
the ChessBase GUI, due to a bug in the CB stuff you will have to manually edit
the CT.INI file.
2) Chess Tiger hash table must always be 12 times some power of two, so when you
select 128Mb (which is not 12 times some power of two), Chess Tiger
automatically uses the biggest amount that does not exceed what you asked for.
In this case it selects 96Mb.
3) If you draw any conclusion after 5-0, my advice is that you should definitely
pick a different hobby. But I'm sure you know that already and that you are not
drawing any real conclusion so early, right? :)
Good luck with your match. Please keep us informed.
