I just tried the position on my Cyrix MX 233 (512 Ko HT).
I use the default configuration except Style=Active.
It plays 1 .. Qd8 (Ok not spectacular but not a losing move...). The real bad
move was of course 3 .. hxg.
With these settings, in blitz mode, when I play the whole sequence of moves, it
plays (a) sometimes 3 .. Kh8 in few seconds or (b) 3.. Nc5 ( < 15 s) if he pass
over Kh8 (depend of hash tables perhaps) -> It *never* considers 3 .. hg with
this setting (That is much better !).
If you set back style=Normal ("default setting"), it considers 3 .. hg then
plays it in few seconds (blitz level).
Conclusion : Keep all default settings including Anti-GM (Smart or Strong) but
*only* change Style=Active -->> it is much more the real Rebel10 than Combo off,
Gm Off and Style=Defensive :-)
I try to understand : the move Nc5 is much active of course, and much
complicated for white... but I don't understand 3 .. Kh8 which isn't more active
than 3 .. hg ; just more safe :-)
Then Conclusion bis : a more Active setting gives (a) one more active move (3
.. Nc5) or (b) one more safe move (3 .. Kh8) :-). Try to understand!
