Say we do call, what's next?

If MP2 shoves and BTN folds, I like folding. If BTN calls, I think I like folding even more.

If MP2 calls, I think we're playing no set, no bet.

The most interesting case, I think, is this...
Say MP2 folds, so it's heads up with the BTN with like $85 in the pot and $360 behind. I think I like CRAI on most flops (no A, no K, not super-scary). If BTN checks behind, I think the turn sucks to play. I have no idea what to do on the turn. Check/fold seems sort of weak, but that's what I'm leaning toward.
