1) raise more pre, 0.40. (and what Rilla said)

2) "standard" pre is 4bb + 1 for each limper so make it 0.5 here. You flop bet is way to small, never bet less than 1/2 a pot until you understand the situations where it would make sense.

Go find the multitude of pot odds threads that were created over the weekend and come back with your own answer about weather to call this turn bet (and what iopq said).

3) did you play SnGs? You bet sizing is waaay small. Again, 0.50 pre, bet at least 3/4 pot on flop. DON'T CHECK TURN!!! Pot control is more relevant when your opponents are aggressive and likely to raise you at any time.

I call because the raise is small and he has to have QJ/JT/89 or a terribly played set.

I don't think you really get eV. And have just seen it used a lot.
