Raises should always be 4 x the big blind + 1 big blind for every limper
e.g If two guys limp and you are on the button with AK in .05-.10c game you should make it .60c.
When OOP, I add about 1 more blind. This makes it a little more difficult for limpers to continue to the flop, and when they do they are (hopefully!) making a bigger mistake. The mistake is actually much larger in the long run, because the effects of larger preflop bets are cumulative. Increasing the preflop bet size by 1 BB increases the flop by 2 BBs, the turn by 6 BBs, and the river by potentially 12 BBs, or 8% of your starting stack. Don't underestimate the power of increasing the size of your preflop bets by even a small amount.
Similarly, when 3betting my general rule is to re-raise to 3x the original raise, but when 3betting from OOP I add one more -- so now I'm 3betting to 4x the original raise. Sometimes There will be a raise and a coldcall, and for every coldcall I'll also add one more. This can result in what might seem to be a rather large raise. For example, consider a textbook squeeze. NL100 CO opens to 4 and the BN coldcalls the 4. My standard 3bet is 3x, plus one more for the BN coldcall (4x) plus one more for being OOP (5x). So if I squeeze here, I'm making it 20 to go.
Its very important to not raise too little in cases like this, and squeezing to just 3x or 12 is simply not enough. Consider what happens. Lets say CO has a hand like ATo. It comes back to him and the pot is now (0.50 + 1 + 4 + 4 + 11.50) $21 and it's $8 to call. He's getting 8:21, or nearly 3:1. Who wouldn't at least call this, with hands even much weaker than ATo? And regardless of you actual holding (let's say you have AJo) you
don't want a call because you are going to be out of position for the rest of the hand. What's more, if CO calls the 3bet the pot will now be $29 and CO will be getting better than 3.5:1 on a call. Not only is he going to call, he would be making a mistake in folding almost any hand he has.
Now see what happens when we make it 20 to go instead of 12. When it gets back to CO the pot will be (0.5 + 1 + 4 + 4 + 19.5) $29, and it will be $16 to call. Now he's getting about 2:1 to call, and we are representing a very big hand. Consider the kinds of hands he is going to continue with. AQ
might call (emphasize might), but if he does he is making a mistake. AK will actually push a lot of the time, and now you have an easy mathematical decision. (Well at least it should be easy!) The point is that CO is going to be folding the majority of the hands he would have called with if you make it 12, and BN will also be faced with worse odds as well, even if CO does make the call.
I can't believe I went on for this long...
