Thanks for your comments.
I hadn't intended to mislead anyone as to what Gnubg plays. I had evaluated 19 plays at 4-ply, botinaturally when I analyzed one more, 11/6 8/4, it turned out that 4-ply liked that play better than the rest, even though, according to Gnubg's estimate, of all the plays 10/5 8/4 attains the lowest EPC. Perhaps that's not accurate.
The score (after 4 games) is: White 4, Blue 4 (match to 7 points)
Move number 16: Blue to play 45

If you made the acepoint 6/1 5/1 you can honestly say "it may be wrong, it may be 38th best but according to the bot it's not a blunder."

I do not think this position supports the idea that 3-ply tends to play bear-ins a little better than 2-ply. But in Blue's previous position in the same game I do like 3-ply's play best:
The score (after 4 games) is: White 4, Blue 4 (match to 7 points)
