Dueller is now working fine with JF 3.5 Analyzer and GNU 0.14.  Duel will
commence soon and I will keep you posted periodically.  Has to pointed out
that whilst JF moves virtually instantaneously on lvl 7 - 1000, GNU takes
several seconds on Supremo which probably means the results would be
different if they both had the same (shorter) time per move.
Rgds and thanks to all for help and advice.

The half way point has been passed.  After 2,500 money games gnubg is
winning and is ahead at the rate of 0.07 pts per game.  I personally am
already persuaded that gnu is a stronger player 8-).
GNU has never yet been trailing and has won over 60% of the individual
sessions (of mostly 99 games each).
I've seen many occasions of what superficially look like dangerous/bizarre
checker play by JellyFish, but I am still mainly concerned about dodgy cube
handling which is far more costly.  I hope at the end of all this somebody
might be able to analyse the kind of positions that the Fish gets badly
wrong.  This would be of far more use than playing with the 'numbers' to
verify what most of us already know about which is the better player.

Well, it's over.  Guess what.  Yep- GNUBG won by a very healthy margin.

After 5,000 money games GNU won by an average of  0.12pts per game.

There are 52 files (sessions) in all totalling 6.3Mb.  I will shortly zip
them into convenient packages and place on a website.  I will post again
when it is available for download.
