I assume your talking hold um? I'm just an average player after 20 yrs.
So, for what it's worth....
It depends where you are at the table. What position. Pre-flop, I would limp in. See what the others do. Be careful on the turn. Read the cards (as well as the players) and look at the possibilities ie: a straight draw, flush etc. If I caught trips, I'd raise, but not tremondously. See if there's a higher pair on the board and watch the action. If your hangin at this point and you have players betting, then BET. That way people are more pot-commited and less likely to fold. And you will catch a bigger pot if you win!
And thats just ONE scenerio! Poker is a game of skill, but luck comes into play, of course. Especially in the silly game of hold um. And now that everybodys brother is playing, well I've seen some REAL SLOP!
I don't know if 1 word of that helped? G.L.
