A few questions about multitabling...

[RandBriscoe]

1. Is it likely to adversely affect your winrate?

2. Do you play even more tightly preflop as result of seeing more hands?

3. I've found it prohibitively difficult to keep track of anyone's betting playing even three tables. I can't get any reads during hands a result and end up chasing only to find after the fact that I should've folded 100 years ago. Common problem?

4. Does anyone refuse to get themselves in more than one hand at a time? As in, folding hands you would otherwise play so as not to be at the expense of your current hand?

5. Am I just an uncoordinated louse who likely types with one finger?

I'm sure this has been discussed 437289 times. Any pertinent information/link is appreciated...
