This morning I bumped up the tropism rewards significantly and shored up when they kick in (after opening (defined as 30% or more of the material traded off, or after that side developed or after that side castled). The next game I played I was crushed in <20 moves with a kingside attack. Since I do not have attack tables, I use pcsq (poor man's attack) as it does ultimately reward having a piece on square but one ply later. Some day I will go to evaluation and attack tables, probably bitboard it all, but for now I have fun without the pain. Stuart
