Dan,

Firstly thanx for your interest on this.

No it doesnt solve it.

Again its time to ply is slower, it get 1 ply less with the same time approx.

Interestingly though, with the blockade code turned on when material<Queen, ie.
all positions in wac230, the score starts at +5 (mainly because of the 2 linked
passers +1 pawn up), but the score goes does each ply, failing low on most, so
after a few plies the score is down to +3.

I think this is good, it didnt give a straight out draw, which it is not, with
the fiddling sort of move the rook around and defend etc, the score starts to
tend towards a draw. Given their are possibilities of moving pawns forward for
both sides, I think this is as good as I can expect from my code a this point.

My chompster will score the move c3 after the sac as about an extra +4 to the
score, so immediately it wont think it got return on its sac, probably if I
pushed the eval of a linked passers higher, it would sac more quickly.
