# =============================
# Private test set nicklas2.tst
# These tests are from 9x9 games.
# None of these tests passes with version 2.7.222.
# I think these problems are "simple".
# =============================
#DESCRIPTION=GnuGo misses followup to D4 push-through.
# This is not as clear cut as it may seem. 2.7.228 values the endgame
# move at A7 to 6.66 points which seems about correct. The fact that
# white D4 threatens both to cut off E5-F6 and to capture D3 through
# a chain of threats (which is what happens in the game) is not that
# easy to understand. A more general atari_atari module could
# perhaps see it, but we are still far from that. I think this test
# should be in nicklas3.tst (harder problems).

#DESCRIPTION=I think G9 is not too terrible here. Very difficult to see.-trevor
# This test illustrates a general weakness of GNU Go: It's poor
# ability to defend its borders. White can enter blacks domains or
# capture the E8 group. In the latter case, whites first move is
# a sacrifice and the capture happens through a chain of threats.
#Added E6, still not thinking G9 is so bad. -trevor
loadsgf games/nicklas/nicklas6.sgf 23
#DESCRIPTION=Very tough position. Even if F1 for B, W E7 is tough.
# This is a very good test case for a semeai module. Black F1 threatens
# to live and creates all the necessary liberties to win the semai.
#I disagree; this it tough; a more clear-cut test case would be helpful
#to better isolate the inherent problem. - trevor
loadsgf games/nicklas/nicklas7.sgf 29
#DESCRIPTION=Tough for white to see attacking B, and linking w/ attack stone.
# The only way to live is to attack a neighbour dragon, e.g. the one
# at F8. But does the owl code really do this by default?
# No, this is up to the semeai module to resolve. /gf
loadsgf games/nicklas/nicklas9.sgf 28
# E1 loses some endgame points since black must capture later anyhow,
# but it saves the group. It could be regarded as acceptable at this

#CATEGORY=TACTICAL_READING
#DESCRIPTION=Fighting Ko here is not unreasonable for B.
#I would delete this regression test. -trevor

#DESCRIPTION=Black must protect his group. H9 is thinkable also.
loadsgf games/nicklas/nicklas14.sgf 43
#DESCRIPTION=PASS here is unthinkable, though RESIGN might be appropriate!
# One eye wins against no eye
#Note: Owl & Dragon status is both critical for the W group. Why
# would B pass when there's a critical group on the board? Owl &
# Dragon status for all of the B stones is Dead. Can a Critical
# group kill another group???

#DESCRIPTION=Protect those borders!
#Added A8, for the faint of heart.
# It's black to move!. The business is to kill white, which is most
# solidly done with C9, but I think A5 and maybe some other moves
