If someone is still interested to put strange positions to board:


Nero 3 has now opportunity to setup almost every kind of positions and
announces how many legal moves there are.

Only limitation is that neither side should be more than ... say 20
queens up.  (It's possible to have e.g. 31 queens per each side.)

My maximum for possible moves has been set to 300. It should be enough.
If you put e.g. 20 extra pieces to board, they will limit the mobility
of others.

Nero 3 dosn't yet consider en passant moves or castlings, but I'll add
these features soon. (Same to promotions to minor pieces.) So these one
must still add self to number of legal moves.

Some evaluation problems still exist... I think that infinite level
could already be tried in correspondence games...
