To expand on my ideas that I posted earlier.

Brain Rook - Keep the same - up to 1000 games (Unless you start getting people up to that amount and they keep on timing out - maybe drop that down to 500 or something - still way more then most will use)

Knights - I guess keep the same.

Pawn - Possible limit their moves during "peak" hours when the server is the most busy. Possible 10-20 moves max during the peak times? Or if you can keep track of how much bandwith a person used, limit that for pawns during "peak" times - since cruising message board also takes away from the server. (During non-peak hours, don't limit them in their moves)

I also still like the idea of letting pawns only enter 1 tournament a month. It does not matter if the tournament is over before the next starts - just as long as it was 30+ days since the last started. (Since now tournaments can be as many as 14 games out of their 20 limit - it is hard for pawn to keep that many games open for tournament) Playing in 1 a month would still let them enjoy the tournament, and use the site to help decided if they want to pay here.

As for non-tournament games, possible limit them to 10 games.
