betting to get the other out

i dont know if what sometimes i do is good or bad for my game. the thing is that when i have a good hand in the flop and there are 2 cards suited i get afraid other players might have the flush draw so i bet to get them out and i win a small pot.
i wonder what is the right thing to do, am i doing the right thing
thanks

In order to delineate advice properly, you may want to elaborate a little more on the specific details of the situation you're talking about. What cards do you have suited, what kind of flop are we looking at, what your/your opponent's chip position is, etc.

There are SOOOO many variables; it's hard to answer a question like that without specifics.

The_Flash is right but as a generality betting large amounts to prevent the flush being hit is silly. Don't settle for a small pot with a 'good hand' if there is only a small chance of the flush. But as has been said, it depends on a LOT of circumstances.

lol people probably think that you are chasing a flush if you bet massively every time two suited cards come out.

Also, notorious flush chaser donks will even call a 3:1 flush draw, without the correct odds. Raise enough to just give them insufficient odds to make their hand, but not _too_ much, or you won't get paid. Should be a profitable strategy if you can muck your hand if the chaser hits his flush.

There are two ranges here you are talking about. If you are talking about ring games learn your odds. There will be times that you will be sucked out. But overall you can maximize your profit by enticing a fish to chase.
If you are talking about tourneys or SNGs, know your odds and status. Depending on the blind structure is how you should play this. You want to build your stack no matter what. At low levels i would play it out to build the pot. At high levels take it down.

This is one of those positional situations where being able to get a read on the players behind you in the hand is imperative. You are correct that cheap cards are dangerous cards, and raising the price is an excellent defensive tool. However, it depends on how many players follow you, and whether you think that any of them would call a big bet that you don't want called. I would have to have a monster in early or middle position. A bit more tempting to posture in late position or on the button. Personally, I have learned that placing bets I DON'T want called is usually a bad idea in general. It seems there's always a donkey who's willing to stay in regardless of the expense or how big a dog they are. Bet the value of your hand, based upon your position, and based upon your evaluation of the opponents behind you.

It's a lot like "protecting your blinds". Even if you feel like someone is stealing, why would you confront them with 84 offsuit? Same here. You want to protect your hand, but not at the risk of all your chips. There's a time to show strength, and a time to wait for a better spot.
