Anyway, I’ve decided to play.
Medium stakes? What is that? To me it suggests $10 to $20 as the small bet.
Is it a limit game? That is, are the amount of the bets on each round limited to a set dollar amount? (Common low limit games are $2/$4, $3,$6, up to about $5/$10, anything higher could be considered medium limits, depending on your bankroll).
Or is it a pot limit or no limit game? These could be considered medium stakes if the buy in was a reasonable amount, say up to $500. In these games, the amount of the bets can vary from the amount of the blind to, well, quite a bit of money.
How much experience do you have? Otto gives some good advice (except I’d scratch that part about “non-connected suited cards where one is a face card and the other is within 5 spots of it (i.e. K-9, Q-8)”, they will cost you quite a bit of money. In fact, I’d forget about the suited connectors lower than KQ, unless you know how to read the board cards and know when to let these hands go.
“Winning Low Limit Hold 'em” by Lee Jones is the book I’d recommend if you have time to find it and read it. I’d also suggest that you play the play money games at a place like Party Poker, not to find a realistic experience (it’s not) but to learn to read the board cards. You need to be able to look at these cards and determine what your best hand is, and more importantly, what hands that the board can make that can beat you.
Experienced players will beat you, but if you know a little about the game you won’t be a total fish, and you’ll learn a lot.
Have fun, and report back.
