In Response To: Average # of Blunders per Match (Giant) (Bill Riles)

Well, Stick asked for opinions about a Giant 32's play against a random human opponent, so there would be various human factors to consider in the Giant's play. But having said that, as an experiment I wanted to test (or illustrate) what I think everyone knows: that it's possible to blunder fairly often and still play very well overall.

I had Gnubg 0-ply play a 9 point match but made Player 1 blunder on every opening response (by coincidence Player 0 won all 8 opening rolls.) Each blunder was as close to -0.080 as I could get. Then I had Gnubg 0-ply finished each game. Then I analyzed the match with 2-ply.

So, Player 1 made 1 blunder per game. Player 1's match statistics:

Gnubg ER:	-7.35
Snowie-equivalent ER:	-3.01

XG PR should, I think, tend to be about half the Gnubg ER, so about -3.7.

So for what it's worth, it's possible for a bot to blunder once in every game in a 8-game, 9 point match, play all other moves as Gnubg 0-ply, and still have ER under 4.0.

Player 1's moves
Total moves:	191
Unforced moves:	148
Doubtful moves:	8
Bad moves:	4
Very bad moves:	6
Cube errors:	2

Player 1's errors
-0.151 (52 13/6 in response to 21$
-0.111 (23 13/11 8/5 in response to 61P)
-0.094 (56 13/8 13/7 in response to 52D)
-0.087 (51 24/18 in response to 53P)
-0.087 (21 24/22 6/5 in response to 51S)
-0.080 (63 13/10 13/7 in response to 21$)
-0-080 (22 13/11 8/4 6/4 in response to 21S)
-0.079 (11 24/23 6/5(3) in response to 53P)
-0.056
-0.051 (wrong double)
