Post-Flop Strategy

Just overcards on the flop

You can bet with an ace or two minor overcards on the flop, but you should fold if someone raises your bet. If someone bets before you on the flop you can call with two overcards, but fold them at the turn unless your hand improves then. You can call with two 'major' overcards (i.e. A-J) if someone raises your bet on the flop. You can also check-call a bet on the turn with that kind of hand, unless the board looks threatening.

A small pair with an overcard kicker

This is a strong hand that you can (cold) call a raise with on the flop. Though, you should probably fold it on the next round if it was raised on the flop and you haven't improved the hand and someone bets before you.

If everyone checks on the flop

You can bet on the turn even if you have nothing. Your opponents will often fold in such a situation, unless they are too many or too loose.

Bluff-bet if the flop contains an ace

Your opponents will often fold in such a situation if they don't have any pairs or an open ended straight, because it's impossible for them to have any overcards when the flop contains an ace. Please note again that this will only work if your opponents aren't too many or too loose. In a game of many players this tactic should not be considered.

If someone suddenly bets into you or raises

If you are considering folding, be sure to first look at the amount of chips that the player has in front of them. If they are out of chips it's likely that they are bluff raising/betting because they know they will go all-in on that hand anyway.
