But your program was already dead in the water at move 25. He just took 
another 10 moves to finish it off.

The predictable spite checks do not help. He set up a position where the 
spite check gets the queen into trouble and Getclub fell for it hook 
line and sinker. Getclub also set about partially creating a trap for 
its own queen which Zebediah did not exploit.

He is a lot stronger than your program and possibly an anticomputer 
specialist. He is winning in about 20 moves it take 35-40 before the 
computer finally sees that.

Spite check 10. ... Be7 was OK

Queen move when 13. ... Ne4 was better

d5 is asking for trouble by restricting queens mobility. It is all 
downhill from here. Whites queenside pawns are already lethal.
19. Bf3 and blacks queen is struggling for safe squares.

18. ... Bc5 (or Bd6, Be7) about as good as there is

It is a fairly simple tactical error. It isn't a good idea to move the 
queen excessively, give spite checks that help your opponent to develop 
minor pieces or to trap your own queen. And letting him grab a huge 
queenside pawn advantage early on isn't very smart either.
