Hi Sarah,

First of all let me say that my testing method is not for those of us who have
several fast computers for their games. I have one 200MMX only.

Both programs are put in equally bad, but constant, conditions. This way I can
see if a new program's version does better compared to previous (in my testing
environment). The point is to see program's "effectiveness/given time". Let me
explain this one a bit. In my games every program is given 60 minutes for a
game. There is no hope for additional time as permanent brain is off. Now, if
program has a good score at this constant time, there is a good reason to
believe that it will be better at any level with PB ON as a successfully guessed
move would mean an additional time. More time + higher "effectiveness/given
time" = good hope for a win.

Returning to Junior I would say it is strong. A very strong and solid program.
When I run a couple of test matches among the top ChessBase engines, Junior was
one of the best engines and one that was giving a hard time to Fritz 6a. My
previous games of Junior 6 (not 6a) vs Tiger 12.0e went equal, both in score and
observation. I have no data for any conclusive statements, but I like the way
this new 12.0f plays.

About 16 MB I would say that it is difficult to give both programs more RAM on a
64 RAM computer. Swapping is not allowed :-). Even in this situation there may
occur some seconds long swapping, especially if both programs use tablebases. A
tipical example would be Junior vs Chess Tal.

Well... I have answered more then you have asked! :-) Sorry about that.

And yes, you are right. That Tiger 12.0f = 12.0e + NSEW=1 and MoreSel=1.

Have a great chess!

Didzis
