C[Black wins by 11.5 points.

GoAhead 19k :  This was a close game. Both programs played carefully 
- as if they were impressed by the opponent's way of playing and fighting 
ability observed during the first 3 games of this match. 
ManyFaces profited by the "joseki" played in the LL corner, where 
B made some shape errors. ManyFaces also got an easy invasion at 
the upper side. Consequently, W took the lead by a few points in midgame. 
But I think the game was decided by yose considerations.  ManyFaces 
failed to take more profit in the LL corner. GoAhead managed to win a 
small tactical fight around g13. GoAhead was also able to reduce 
ManyFaces' center mojo to a tolerable size.  These small fights decided 
the game.

Total result of the lader match: ManyFaces - GoAhead : 1-3
