i agree. I think that before a game can start, one have to complete a random tactical trainer puzzle. Everyone will have a baseline tactical rating. This rating will give any opponent an indication of your insight into the game.
It would be a great surprise if someone with less insight to win someone else with a greater tactical experience.
I think having a rank for tactics trainer would be cool
I want to see how my score compares to others.
also cool would be chess mentor
