This is from my experience, and from the few coaching sessions i've had with friends online.

Pre-flop:
If you are going to play, you want to be the aggressor. Unless there are a lot of limpers in the pot before your action, you either want to bet or fold. Depending on your starting hand, you may want to limp too, or you may want to bet. If you have a premium hand, you will want to raise to try and knockout some crappier hands, so they don't hit a 5-9 straight vs your AA.

Betting:
Standard rule of thumb - bet 3 x BB + 1BB per limper. So if the blinds are at 50/100. You are in seat 7, and there have been 2 limpers in front, your bet would be 500.

If someone has riase before you, you want to be bet 3x their bet.

If you have 10bb's or less, or getting close, any play you have will be shove or fold. Your best bet will be to shove an unopened pot, unless you have a monster then you should just shove.

Also, if any of your bets will put 1/3 or more of your stack into the middle, you should just shove anyway. Any lesser bet, and then a shove by the other player, you are pot-committed and will have to call anyway.


Post Flop
Alright, you've seen a flop. You hit top pair, two pair, set, straight etc., the usual post flop bet for me is 2/3 of the pot, and again if it puts enough of your stack in the middle, you should just shove..

You've seen the flop, and didn't hit. 2 options.
Option1- Continuation bet - you bet 2/3 of the pot hoping to get a fold. If you still don't hit after the turn or river, let the pot go, unless you are really sure you can get a fold.
Option2 - Let the pot go, cut your losses.

You've flopped the Nuts
If you flop the best hand, no other combinations can be made with the turn and river to beat your hand, you many want to check the flop and hope to get a bet from the opponent, cause chanes are, they won't call if you have the absolute best hand.

Turn and River Pretty much the same as betting on the flop. You should always make your opponents pay to see your hand, don't go offering free information to them that will let them know what kind of hands you are playing, and how you bet them.


remember, bet or fold. no flats, flats get you no info on the opponent.
