not meaning to detract from RHP, which can't be topped, I've been ill for the last few days and not capable of thinking hard enought to play chess.
Instead I've found a purile but entertaining game called Tactics Arena http://www.tacticsarena.com/. It bears only a passing similarity to chess, but it is a turn based board game and the correct martialing of your forces will win the day (with a bit of luck).
It's good to pass a few hours, if you like that kind of thing. And even in my depleated state I expect to be in the top 3 players when the rankings are updated next Sunday. The server is quite busy but keep trying for a minute & you'll get in.
If you want to play me there, look for 'freak'.
I hope no one finds this ad bad taste
