Subject: How can I see a "wins, draws and losses" statistic for an opening move?

Ruffian 1.0.5 gives the information about wins, draws and losses percentage for
main moves on each position from its opening book.
For example, on the initial position Ruffian shows:

  Move    Played   Prop[%]  Score[%]    Learn     +        -        =
  d4        9911    42.81%    55.46%     1.00   28.46%   17.55%   53.99
* e4        8082    35.44%    56.30%     1.00   30.10%   17.50%   52.40
  Nf3       2609    11.30%    55.63%     1.00   27.41%   16.14%   56.46
  c4        2228     9.83%    56.67%     1.00   30.25%   16.92%   52.83
  g3         118     0.45%    49.15%     1.00   24.58%   26.27%   49.15
  b3          31     0.12%    53.23%     1.00   35.48%   29.03%   35.48
  Nc3          6     0.02%    50.00%     1.00   33.33%   33.33%   33.33
  f4           9     0.02%    27.78%     1.00    0.00%   44.44%   55.56
  c3           4     0.00%    25.00%     1.00   25.00%   75.00%    0.00
  b4           3     0.00%    33.33%     1.00    0.00%   33.33%   66.67

However, Ruffian's book is not big.
If I want to know, what move is best to punish some wrong move, Ruffian fails.
For example, if I want to know what to do after 1.d4 e5?, Ruffian 1.0.5 shows:

  Move    Played   Prop[%]  Score[%]    Learn     +        -        =
* e4           9   100.00%    50.00%     1.00   22.22%   22.22%   55.56
Book: cache 74.34%, time 0.15 sec
Suggested move: e4

Which FREE engine has bigger opening book with the same possibility (i.e. shows
the number of wins, draws and lossses)?

I see Ruffian is the ONLY program that shows opening database statistics Andrey Popov 02:52:01 04/30/05
