Rework the "unsupported" penalty into a "supported" bonus A pawn (according to all the searched positions of a bench run) is not supported 85% of the time, (in current master it is either isolated, backward or "unsupported"). So it made sense to try moving the S(17, 8) "unsupported" penalty value into the base pawn value hoping for a more representative pawn value, and accordingly a) adjust backward and isolated so that they stay more or less the same as master b) increase the mg connected bonus in the supported case by S(17, 0) and let the Connected formula find a suitable eg value according to rank.
