@zenbitz:
Yes multitabling is the problem and then again it's not, really. My main target is Mr Fish. And they don't usually play 8 tables. And even if he plays 2 or 3, the fact that he is involved in the pot should be enough to have him fully concentrated on my table => tells should be more or less reliable. (makes sense?)

Actually the only two problems I see are: 1) multitabling myself, so it's hard to spot these subtleties and 2) server lagging
