...since he's unknown, I think you can also include KQ, a passive KK and even 77+... def 99 & TT. I've seen this happen twice last two days. Vil looks at the flop bet as strictly a CBet, takes your turn check and river checks as whiffs -- gets some confidence from the second J hitting and u checking the River after PF & F agg -- and figures u might be one of those raise any PP from EP and now scared of the OCs or sitting on something like AK. 1/3PB on the River doesn't exactly scream OMFGIHAVETHENUTS to me.

I prolly would have bet $2.50 on the Flop 'cause of the draws, bet 5 into the Turn, and if he's still with me, C/C to a reasonable R bet. But then I invariably F- these high OP plays...
