Why would a good player snow from draw 1? There's what, 9sbs in there at the point at which BB decides to a snow, and he's going to have to risk another 5sbs across three streets against two players, hoping neither makes?
I guess the BTN sounds bad and the BB probably knows it, so maybe the overlay there makes it worth it to just ram and jam as a snow occasionally? Any concept of how frequently this is worth doing? Do you use your holding as a randomizer, e.g. do this if you have a hand like 4
7
5
8
(or basically anything with four low cards that are only playing two of them)?
