I have some, but in my own format, however, I managed to implement
the gtp in Golois this week, so I will progressively transfer my
test bases to gtp.
Ok to start with connections.

better move ordering, optimisations on tree search, some functions like
simple_connect_three_moves missing, capture functions... and some code
for non transitivity that needs improvements :)

So maybe, we could have tests like this for the gtp :

1 connect D8 D6
#? [1 (F8|E8)]
2 disconnect D8 D6
#? [1 E9]

calling functions that sends back the connection status and the
associated moves ?

Do you have a standard method to produce sgf trees from reading ?
