A friendly tip -- any time a hand goes to showdown (even if you aren't involved), make notes if you notice anything that can help you in the future against this opponent. Stats alone will not help you in the long run, especially if you are just relying on VPIP/PFR.

Here are some examples of common notes I take during a session (made up):
- Plays TPNK like the nuts
- Flopped NFD, checked all streets when missed (or: played 98s flush draw for stacks on flop)
- CO: raised 3xbb with KTo, bet pot all 3 streets with air
- UTG: limped/called with AQs, flopped top pair OOP, checked flop, checked turn, minbet river

You get the point. Then, when you play against this villain in a hand, you have a much better idea of how he's playing and how to adjust his range after each action.

Finally -- when you post hands here, include those reads. You'll get significantly better replies.
