   2 # Simple script using Pachi for rating all moves in a given situation.
   3 # Pachi will analyse each followup move and suggest a winrate for it;
   4 # higher is better.
   5 #
   6 # Usage: tools/sgf-ratemove.sh SGF MOVENUM PACHIARGS...
   7 #
   8 # Note that this script assumes dynkomi=none and does not show
   9 # dynamic komi information. (Would be trivial to add but it's tricky
  10 # to interpret the data.)
  11 #
  12 # This script is dirty and insecure for untrusted input!
  13 #
  14 # Example: tools/sgf-ratemove.sh progame.sgf 120 -t =500 -d 0
  15 # ...to get 500 simulations per each possible move in programe.sgf
  16 # at move 120.
  17 #
  18 # If you want to know more details on what is Pachi thinking about the
  19 # various moves, remove the `-d 0` part. To improve the accuracy of values
  20 # (at the expense of run time), raise the value of 500 (try 2000 or 10000;
  21 # 100000 will usually already take couple of hours). The values will be
  22 # most useful in the middle game; in fuseki and most yose situations,
  23 # expect a lot of noise.
