There is alot of site's for Texas Holdem Tips & rules ..... just google Texas Holdem
a couple things to consider
You never have a bad hand until you see the 3 card flip,
Never fold when everyone is checking
When your low on cash sometimes its best to go all in instead of fold so you can refill chips for the next hand
as long as there are no raises before the flip always stay in
any 2 cards in your hand can be a winner, for instance if you have a 2 & 3 in your hand the flip could be two 2's and a 3 for a full house , you just never know.
High card is lowest hand,
