I'm behind the times! I think when I first learned, komi was only 4.5 points.

I am struck again at how non-obvious the winning setups are. It would have taken me a long time to start a rabbit behind the trap (in the back row case) and an even longer time to start a rabbit on the back row (in the case where both home ranks are available).
Anyway, JDB, did you repeat this analysis for DCR vs DCR after you completed the six-piece tablebase? Clyring renewed my interest in this question in this thread. Of course, with clueless entered in the World Computer Championship, I don't expect you to have time at the moment for any other hobby coding, but I thought it couldn't hurt to raise the question.

The game of Arimaa as a whole, since it is finite and drawless, is either a first-player win or a second-player win, unlike chess, which is probably a draw. We can expect that, the better we get at Arimaa, the more our actual win percentages will tilt in favor of the player with the theoretical win. One way to interpret the fact that actual winning percentages are about 50-50 is that we still stink at Arimaa! |

The theoretical win has many many more moves than the games we play. So by this theory, the better we get, the longer the games will get. Which also means that all you aggressive players are making us all play worse . Not only do we stink at Arimaa... but we're getting worse!
