For our purposes, let's assume we are playing PL 5-Card Draw...

Most hands in 5-Card draw are pretty straightforward in terms of "standard play" - pairs you might limp and draw 3, 2 pairs and draws you draw 1, made hands you raise and stand pat (and hope someone hits a lighter made hand - or just thinks you're bluffing).  The beauty of these hands is that they leave a lot to question in terms of what you hold post-draw.  For instance, when you draw 3, while your opponents may be able to put you on a pair before the draw, they have no idea what (if anything) you have improved to, and in that manner it's a little difficult for them to make a decision with a large range of hands when you bet.

Three of a kind, however, is a completely different story.  When you draw 2 cards, it's fairly easy for your opponents to tell you have three of a kind - and so, when you bet afterwards, you will only be called by those who can beat your hand - and this makes decisions even easier when you raise pre-draw.  Well, raising pre-draw is pretty much a must, which means the only option we have to disguise our hand strength is to draw 1 instead of 2.

Once we do this, though, we run into a potentially bigger problem - while we may have tricked our opponents into thinking we have either 2 pair or a draw, it could cause them to re-raise us post-draw with a lesser set or even worse - they'd be bluffing without even knowing it.  The problem with this is because they'll be displaying genuine confidence in their hand, we'd be forced to fold our better hand (as it's not really unheard of for someone to outdraw a set).

Given all of this, what exactly do you do in a situation such as this?
