Tests from KGS tournament 11

[gunnar]

KGS tournament 11 had its usual share of bad moves. Game records can be found in source:regression/games/kgs/tournament11.

GNU-firstgo.sgf

• Move 58: A1 meaningless. E12 or K4 good. (A1 isn't played on level 10 but on level 11 and up.)
• Move 62: G4 meaningless. K3 locally way better.
• Move 86: M5 kills.
• Move 104: J13 locally better than L12.
• Move 142: G13 accomplishes nothing. Better play the last point at N7.

GNU-viking5-1.sgf

• Move 48: Urgent to defend on the left. D6 looks simplest. Does any other move work?
• Move 88: H11 locally better than K10.

GNU-CrazyStone.sgf

• Move 12: Better to invade a corner straight away. L11 best?
• Move 18: L8 looks strange. J2 or L11 make more sense.
• Move 58: B5 looks like it leaves a fair amount of aji. B7 better?
• Move 100: Better to fix up the connection along the upper edge with E12.
• Move 108: Urgent to live in the upper left corner with B12 or B13.

GNU-viking5-2.sgf

• Move 42: F2 should be played immediately.
• Move 54: E6 doesn't look biggest. B12, M2, and E1 bigger?
• Move 56: N4 looks locally bigger than L3.
• Move 82: C1 kills cleanly. C2 lets black make ko (black D2, white A2).

CrazyStone?-GNU.sgf

• Move 13: Blocking at C12 looks better than pushing at D11.
• Move 17: Urgent to reinforce upper left with C12 or B7?
• Move 45: M9 gives a clean tactical capture which looks superior to the game move J12.
• Move 77: G13 secures two eyes for the top black stones and a trivial win of the semeai.
• Move 87: G13 is still sufficient to get a seki.

firstgo-GNU.sgf

• Move 55: C1 is risky.
