Now to get paid:

Fourth Street
Once fourth street has been turned, you should have a good idea on what you are going to do. If you were on a draw and your card came, you can attempt to check raise, or you can just bet. In both situations you have a very good chance of winning the pot if you played the draws that I listed above. If you had a medium pair and the next card gave you a better hand then the top pair, you should bet. Since you have assumed your opponent has top pair, you know you have him beat and you need to bet, since the right play for him is to call, and maybe even raise. Yet if fourth street didn’t help you, then you should check, or fold if your opponent bets. Lastly, if you had top pair before the flop, and fourth street is below your pair you should bet or call. If the card is above your pair you can still bet, but watch out for a check-raise.

Fifth Street
In limit holdem, fifth street is a time where you try and get the most money from your opponent if you have a good hand, or save the most money if you are uncertain about your hand. You should have a pretty good feeling about what your opponents strength is, and from this you should determine if you should bet or not. Rarely you will find a player who is trying to bluff you, but remember to watch for it and try and catch their hands in the cookie jar.
