Sjeng only considers Bd7 at ply 4 and ply 5. Even your Celeron will blaze past
these depths in a fraction of a second.
If I play out Bd7:
Sjeng: go

It takes only 3 ply to see that the move is completely losing. Compare
this to the score and depth your logs shows (Where are the mainvariations
anyway?)
