>Is the problem as bad as in Fuego? Maybe not this specific problem, but similar problems.
Approaches like adding a 2-liberty feature helped Pebbles. But the difference is not as large as you would like. For example, your program will shred other programs that lack a 2-liberty feature. But humans have a 2-liberty feature, and a 3-liberty feature, and so on. And if the human is of sufficient rank, then his error rate on those features is quite small. So you still run into problem cases. It just happens one move later than before. Note that the combinatorics suggest that 3-liberty features will be very hard to write correctly. A 2-liberty feature is mostly branch-free. E.g., one player ataris, and the response is to capture if possible and escape otherwise. When you have 3-liberty features, there are now 2 ways to escape. Additionally, you can defend by capturing or by reducing an opponent to 1 liberty. Even the 2-liberty feature is hard to get right. I expect to be fixing mine for many years.
