so you sit down with 500 on a 5/10 table, which is a smallish stack. your "competition" is comprised of people who can barely figure out the value of the hand they hold.
you can easily win 5big blinds every 100 hands playing this strategy:
If its a passive game with lots of calling preflop, call any hand if 2 people have called before you.
On the flop, play fit or fold.
If thats not the case, play only good hands, where good is:
big pairs (tens or higher)
AK, AQ
KQ if you wanna be fancy.
Hands like AJ and KQ are big losers for inexperienced players because they always get into big pots when theyre dominated.
A good made hand on the flop is top pair top kicker. Anything less and you want to keep the pot smallish.
On the button, play any hand. Always raise preflop if you wanna play. Especially in No-limit games, position is the most important thing in the game. More important than the actual value of your hand.
In general, play fit or fold. Bluffing doesnt work against people who dont play seriously (which is the case in the lowest available stakes games).
Dont give a shit about defending your blinds. While this is very important in a competitive game of poker, its just 1big blind. Not that much compared to the 50 big blinds youll lose finding yourself with K9s on a K72 rainbow flop trying to figure out whether the guys really holding AK.
