Grunching...

1. I probably bet 150 on the flop, but fine otherwise.

2. I fold knowing nothing about villain. But with your read, I don't mind the push. Normally, best case his range is probably A7+, KQ+, any pair. You're not in good shape against that spread.

3. I would have bet half the pot on the turn and checked/folded from there. I fold the river because you're likely splitting at best, and the pot is too small.

4. Given your read, I call instantly. I think I'd call or push most people here, except complete rocks.

5. From a tight player, the UTG limp scares me to death. Against anyone else, I prefer to check-raise all-in if I can maintain some fold equity.
