There is a simple solution. look for the first 5 options for 1% of your time. If the difference between the best move and the 5th best move is more than a pawn then the position is tactical otherwise it is positional. You can change the numbers but the idea is clear. This is of course not a perfect solution but does someone has a better idea? I do not know if Fritz5.32 is better in tactical positions. I read that Hiarcs7 is a good solver so it is good at tactics and I know about ssdf games that Fritz5.32 won Hiarcs7 because of better endgame play and not because of tactics. Does someone has a proof that Fritz is better than Hiarcs7 or Junior in practical tactical positions? Another problem if you change the engine often is that Hiarcs cannot use the fact that it does not clear the hash tables if it is not going to play the next move. Uri
