I try to minimise the mobility factor and find other terms in order to achieve about the same effect. In many positions a heavy weight on mobility will give strange play for Terra. But herre it would help. One problem here is the K-positions. Terra gives a lot of punishment for the white K position that doesn't have any pawn shelter. In an open position that would be ok but here it is not. //Peter >Regards, >Miguel
