I play mostly Ring games, and Tournaments, almost exclusively on-line, and I will go in early with almost ANYTHING, just to see how the table is... be a little aggressive, steal a few blinds, before a flop, if there are no raises, and even if there is a raise, but not too big, ANYTHING is possible. How many bad beat stories involve the Big or Small Blind??? I bet at least 75% of them, the Blinds are the most Dangerous with a 2s 6h 10c flop...or something similar to that, I have seen MANY KK or AA beaten by 2 pair, say 8's and 3's , by one of the Blinds...
See??????
One of the things which drives me NUTS is going all in with a small pair and some idiot call with A4off, and then the board hits 2 pair.
