HAVE FUN.
Just play tight and play with position if at all possible. If you have a good hand then play it strong, most weekend players try to be cute and slow play big hands and overplay bad hands.
Folding while not in the blinds is free and you can not lose money by not being in a hand.
Only play good starting hands unless you are in the blinds and can see a flop for cheap.
If you ever wonder if you should fold, that means you should fold.
If you have a open ended straight draw or a 4 card flush after the flop you have a 33% chance of hitting it before the end of the hand, at the turn you have an 18% chance.
To calculate your outs percentage after the flop take your number of outs and multiply it by 4 and add 2, after the turn take your number of outs and multiply it by 2 and add 2. (these are +/- about 1%)
