Playing in a $100 max NLHE game with blinds at 50c/$1, I am in the small blind with QhJh. First player raises to $4 and gets called in 4 places, so I call too.  Flop comes down 5-5-2 rainbow a

Some of this will be dictated on what people have observed you doing beforehand.  Have you made similar moves to this before or are you perceived as a tight player who is to be believed?  Look at it from the player’s point of view holding TT.  After you re-raise, the first player gets out of the way.  Ok, he may have had AK and had to fold, or he may have believed you.  But if a player in the small blind here really did have a 5, would they re-raise all in here or would they put in a small raise or even just call and wait to pull the trigger on the turn?  Your bet is slightly over the top and looks like a bet that doesn’t want to be called, which probably contributed a lot towards TT making the call.  Then again, at this level, there are still players who don’t consider any of that, they just look at their own cards and decide that TT is too good to put down!  All in all, don’t give up on looking for opportunities to make plays at people, but first of all make sure they are the right people and your table image is right. Finally, make sure you play the hand in the same way that would be consistent with the way you would play a monster hand in the same position.
