If I use time to count EBF it is 2.9. So ply10=67s, ply11=193, ply12=560. So not
twice as much, but you have a point. And maybe EBF is the reason why I got odd
results: my SEEless version seemed equally strong as a version with SEE on fast
time controls, but it was weaker at longer controls. So SEE and a low EBF pay
off only at high depths.

True, I have only check extensions.
