Hi Peter: How about mobility as a principle to take always into account? A closed position is one where mayor pieces lose room to manouver. From that simple fact some also simple rules follows: a)to penalize in a degree pawns chains located in the same colour squares than the bishop IF just one bishop stay in the board. b)to penalize moves where, if not a clear an sustantial advantage is won inside the horizon of search, the piece moved lose more than a certain proportion of his previous mobility. Attention to the fact that those rules should apply only if nothing compensate the losing of mobility. Shpuld be as, let us say, one of the last rules to be seen after everything else did not give nothing. I presume that with only those rules in operation Terra would had avoided that awfully ugly and losing position Fernando
