I normally only play 3-4 tables. I've done 6 before but I can only play for an hour like that. I'll start missing check raises, and I feel like a robot. I really can't see how you guys play 8 tables, and still play good. Also when you play 8 tables do you ever time out on your turn because you have a hand at 3 other tables?

I play 7 to 10 tables on a 17inch crt piece of crap. sometimes i do time out, sometimes i fold monsters, sometimes i raise junk, sometimes i forget what position I'm in and try to raise for a free card, only to find I was the small blind and had checked. It can be very funny sometimes. I've still managed to keep a winrate of over 3BB/100 at the 1/2 tables.

I would suggest for the OP to drop in stakes and then try 2 tables. If you've been single tabling for a long time, your brain is going to take longer to adjust. Kinda like the relationship/break up thing.
