Villain is a very tight and aggressive player i played with many months ago at 1/2, prty sure he's loosened up some since then though. We've not shown down any hands at this table, but he did raise the flop after calling my 3bet pre a while ago in position, and i folded. I'm playing like 18/16 and aggressive.
