Sorry for using an extremely slow machine, the big ones are now busy. The
position is very complex, and I do not trust any computer analysis in the
endgame. Still, I wonder what does crafty see as compensation for white's
material deficit (rook and three pawns against queen and bishop) at the end of
the last PV.
