I think I played this AA decently well, is this a completely standard way to play against a decent tag? (I always somehow find myself sitting to the right of them lol). Meh, just noticed how weak my flop line was here, I guess I should have made it closer to $4.5 - $5. I guess my turn check won't be liked by many people, but I think I'm either wa/wb, and if I lead out the turn, either one of those hands can, and probably will, raise me. This would leave me clueless as to what to do. If he bet on the turn, I pretty much would check/call, and also check/call on the river. Since he checked, I just tossed up a $5 value bet on the river to either get his K to call, or maybe he would bluff with a raise if he missed. Of course, if I was crushed already he would raise, but I think by checking the turn I would save myself some money that way. Thoughts?
