[marbles]

"How many people raise preflop and why?"
--I'll raise Axs after a bundle of limpers if there's a good chance I can buy the button and get a free look at the turn, or if people have been giving my preflop raises entirely too much respect postflop. All told, it's something I'd do about 10% of the time. In this particular situation, with a LA to my immediate right, I'd limp.

"How many people will take one off when they have a nut flush draw and a rainbow board hits with one of your suits?"
--If the table is passive enough to almost guarantee some callers and no CR, I'd probably chase here.
