Machine is AMD Barton 2200+.

Very strange listing by Prodeo 1.0

First selects f6!! in 0 seconds, remains stable till ply 11,
and then starts to twist between f6/Nf3

Evaluation is locked about +1.20.

I think only Ed is able to clear this.

Best regards (and congratulations to Ed for best Rebel/Prodeo evaluation I
have ever seen in chess engines)
