A nice draw (played badly?)

[Zag]

You are HOPING you have a little worse than a coin flip, in which case you barely have odds to draw: http://twodimes.net/h/?z=996304

But you might be up against a set, which you don't have odds to draw against: http://twodimes.net/h/?z=996279

Or a better flush draw, which you don't have odds to draw against: http://twodimes.net/h/?z=996308

Or a better draw with a pair, against which you are dominated and a huge dog: http://twodimes.net/h/?z=996309

So, you might be barely positive EV, with equal chance of being dramatically negative EV. I'll let you draw your own conclusions.
