Interesting to see the varying scores and different PV’s from the different
chess engines.

My amateur program, Deep BASIC, spewed out the following.  Wildly fluctuating
scores but in the end thinks black is winning.

My Scisys 2150L has after thinking all night has come up with Rxg5 (5 ply) with
a score of 0.13 in favor for white.  My other chess computer, a Scisys 1850,
thinks c1=Q is the best move.

Cheers,
Tom.
