re: Poker & tricky mtt question
I get this a lot, and the answer is "it depends". How badly did you miss?
If you are MP +1 or +2, and get flat called by the button, and miss the flop, does it make sense to fire the first bullet? Not really. If the button checks behind, I would continue to try to keep to pot small (check or check/call less than 1/3 the pot), or toss it and wait for a better hand.
3x BB out of 15-20 isn't bad to toss away. Its when you try to semi-bluff with two overs and firing c-bets that gets expensive.
