Go up one level in this thread

I find your results very interesting.

What puzzles me, is the large branching ratio from one iteration to the next one
which you obtained. I'd thought, that you get a factor of 4 to 5, provided you
have a resonable move ordering, whereas you have factor of ~20. Could it be that
your move ordering is very poor ?

I assume, with an improved move ordering, the effects, which you have observed,
will also become less drastic.

Nevertheless, it might be worthwhile to try your suggestion regarding en
passant.

Thanks,
Uli
