[gnugo-devel] new tests

[Gunnar Farnebäck]

Three new tests. The two reading tests are fairly similar and almost
certainly have the same solution. This is the position:

   A B C D E F G H J
 9 . . O . O . O . . 9
 8 . . O O O O O X . 8
 7 . . + O X X X O X 7
 6 . . X O X . X O . 6
 5 . O O X + X X O O 5
 4 O . O X . X . X O 4
 3 . O X X X X X X O 3
 2 . X X . . X O O . 2
 1 . X . . . X O . . 1
   A B C D E F G H J

GNU Go thinks that G2 can be captured at J2 and that B3 can be
captured in ko at A3. A likely solution is to revise
superstring_break_chain_moves() to also pick up moves attacking
strings with three liberties. This may be a good exercise for someone
who wants to get familiar with the tactical reading code. Just
remember that solving the testcases is only part of the problem, it
should also be done with minimal slowdown of the engine.
