Usually even programs at Gerbil level beat tscp but programs may lose not only
because of bugs.
Note that List4.61 lost against tscp in because of bad opening choice that was a
result of a bad evaluation.

3rd Division Group B
I believe that the problem was not bad search but bad evaluation that caused
list to play stupid moves in the opening 1.e4 e5 2.Nf3 d5 3.exd5 e4 4.Qe2 when I
guess that later tscp did not see more forward but simply got a better position
and won the game becuse list4.61 had no plan and maybe in bad position it
decided to defend against threats that tscp even did not see.
