I give the analysis of the programmer again when sjeng never liked to play Rd4 and got depth 11. I also suspect that the only fair way is to replay the game from the first move and to delete learning files if there are learning files because programs learn from previous search and pondering also can help because sjeng predicted 33.Qg7. Maybe Gian can also send a special version that never play unless it gets at least 200000 nodes per seconds for testing. I do not know the speed of your celeron but Gian can get an estimate for it based on the number of nodes per second in the initial position. Sjeng: go Middlegame phase.
