fold preflop, checkraise allin flop

[/ QUOTE ]

What does check-raising all-in on the flop accomplish here? About the only hand hero is behind (and he's behind almost anything villain could have here, I would think) that I can see folding is TT.

In any event, fold pre-flop (and don't limp marginal hands from upfront). If hero must play this hand, he should raise it pre-flop, too.
