I had seen some comments that the P1 and P2 versions seemed to be playing nearly identically and Arimabuff mentioned that he thought P1 was actually playing like a P2 bot. Last night I checked one position and commented on the game for the P2 bot that it was actually searching the P2 depth. Tonight I got a chance to pull a couple positions from the P1 bot games and check them.
The first was move 17s from game 82789.
17b

The move played by opfor2008p1 is:
17s mb6n cc6w cb6w mb7s
With my copy of opfor I searched to depth 4(p1) and 8(p2):
depth 4
pv eb4e ec4e ed4e ee4n
depth 8
pv mb6n cc6w cb6w mb7s w Mf7n Cc2w he8s Mf8w
Then for game 82716 move 31g:
31w

The move in the game was:
31g He2w rf2w Ra2e
Locally:
depth 4
pv Ra3n Ra4n Ra5e Rb5n
depth 8
pv He2w rf2w Ra2e
As you can see the P2 search matches the move actually played in both cases.
