1. Pushing is okay - if you don't want to have a flop for t150.
2. horrible. There is no reason to get cute because of the increased buyin.
3. I'd push 6 handed
4. Guess it's okay. I don't like calling off 100 here though
5. I might just call the flop. I don't care about the flushdraw
6. Don't like it
7. Horrible
