Vinland, you said yourself he's an unknown and you're giving him credit. So let's make a flop range, yes?

AK, AQ, KQ, AA, KK, QQ, JJ, maybe AJ/KJ. If we raise him here, what is he continuing with? TP hands, Over pairs, Sets, Straight draws, So QQ, JJ, AA, KK, AQ, KQ, maaaybe AK. Stove our equity against that range. We need even more equity than we usually do b/c there's a chance we'll be raised if we 3bet. When there isn't enough equity against their continuing range when we 3bet, we cannot.

Start all of your hand analysis with credible ranges for every street! [/i]
