A beginner cannot beat GNU Go, but it should be easy to make up 
positions where a beginner can find the right move and GNU Go cannot.

These are much too complicated to understand by beginners.

I have come up with a simple position where GNU Go fails: it is a 
position with two ladders. The best move is a double-purpose ladder 
breaker at the intersection of the two ladders. GNU Go plays terribly 
bad when ladder-breakers are involved. I wonder what other Go programs 
play in the attached position.

Also, I would appreciate if some strong players could check this 
position for correctness. I tried to make the position balanced so that 
if White does not play in the center, then it loses the game, and if it 
plays in the center, then it should win. But I am really not sure at all 
whether it is balanced or not.

Thanks, by the way, to all who replied to my original question.
