Pretty early on in this session. Most players seemed like solid TAG's and every button liked to raise when it was folded to them. I 3-bet twice within 4 orbits (with good hands) but got folds. Here I decided it was either a fold or a 3-bet as calling seemed to be too weak against his wide range on the button. How shall I proceed on the turn? What could he have called my flopbet with?
