Drawing 2 increases your odds by almost 1 draw to 1 out, or 2%. The purpose of holding a kicker with a pair is not to stop someone who bluffs too much from bluffing, but rather to stop someone who bluffs too little from bluffing at all. Someone who bluffs to much should be encouraged, and then called. That is a basic principle, you want ppl to bluff at an improper frequency. That is why standing pat with AA against a drawing hand is only useful against ppl who dont bluff much, it lets you fold when they bet. Against someone who bluffs too much drawing three and calling his bet is proper(see TOP). As to the origonal question ... drawing 1 and drawing 2 should be a part of your game. It basically comes down to who your opponent is. Usually I like to do both at the same table, against the same ppl, drawing 1 more than 2 ... it is good to mix things up, and if you are going to be pretending to have trips by drawing 2, than actually having trips once in a while is a good thing. You will often find that ppl just dont believe you when you draw 2, especially if you are in position.
