Villain sat down with a 44 big blind stack and posted under the gun.

Questions:
1. I assume a three bet is standard here, correct? I figure to be ahead of his initial raising range. Also, I don't want to smooth call out of position.
2. After his shove, I'd be calling 3.20 to win 4.40, or 1.375 to one. If my math is right, I'd have to have over 70 percent equity versus his range to profitably call. So, despite his donkish behavior so far (utg post, short stack, etc), I think a fold is in order. Are my math and my thinking correct?
3. What do you think of my three bet sizing? I guess 3x is usually standard but I'm starting to think that a smaller three bet might be better in this case. My reasons are that a smaller three bet will open up the bottom of his calling range. Also, I think a smaller three bet will also discourage most players from smooth calling with monster hands (AA, KK, QQ), since they probably won't want to leave a lot of money behind. Since I'm folding to a four bet, if what I believe is true, then a smaller three bet would allow me to play more perfectly against my opponent's range, in addition to being cheaper.

Sorry if this is a lot of questions for such a simple situation, but this hand really got me thinking. I'm especially curious to hear what more experienced players think about the bet sizing question.
