Yes.  I meant net mobility of course (white-black).

In the simple Othello I wrote a while ago, the number of available moves seemed
crucial to evaluating the worth of a position.  I therefore like Dan's
definition that mobility is number of available legal moves.

Of course, if you are about to deliver mate then one move is enough, no matter
how much mobility your opponent has.

I tried mobility for bishops, as number of free squares, but it was not a great
success and costly to compute.  There are obvious case where a bishop on g2 is
valuable despite its limited mobility.  As human players maybe we see the
potential mobility (rather than actual), which is why I have been concentrating
on blocked pawns.

Just wondered how other did it; and whether they did it at all.

Tiger fascinates me.  It always seems to have good move available.  Mine often
gets itself tied in knots.
