Would be interesting if a rollout of a sample of those cases agrees with 0-ply or 2.

On gammonline "Stick" claimed that 0ply doubled early. That came as a bit of a surprise to me, so I set gnubg up to play expert/expert. After around 20000 games gnubg had used more than half of the computers memory and I cancelled the match at that point. Then I did a 2ply analysis of the cube actions only. The statistics is striking, Almost a third of 0ply's doubles are considered early and the ratio (early doubles):(missed double takes) is 10:1. The cube action of 0ply is still excellent though. Perhaps all this is just a manifestation of gnubg 0ply overestimating the equity of the player on roll, but I still found it interesting. Christian.
