standard preflop 3bet amount for microstakes cash games

What's the standard preflop 3bet amount for microstakes cash games? I know this is a broad question, but I'm just curious about rough a guideline.

Let's just take a basic example when you face one PF raiser: EP open raises 3xbb, everyone folds, LP (hero) holds AKs. The villain is a vanilla reg. Would you base your 3bet size on the % of the pot?

What if there were was a PF raise caller and someone else who cold calls? Would the bet size change in terms of the % of the pot?

Just looking for a general rule of thumb. Thanks.

Like you said this is a very broad idea and can definitely change depending on the situation you are in. Effective stack sizes, table dynamics, any reads on the villain, etc. However, I have seen a couple ideas before that come in handy as a general rule. 3-4 * original bet can a good starting point. So say villain bets 200 a good raise would be around 600.

Now if you are getting callers after the initial raise this obviously won't be as useful. In these scenarios you are going to have want to use the pot size to determine the size of your bet. In this case you are looking for somewhere around half pot to a full pot bet. In this situation if you are getting to a point where your raise is going to be more than about 1/3 of your stack, you may want to think about just pushing all in. Committing more than a 1/3 of your stack at this point is getting you very close to being pot committed any.

I hope that gives you a little info.

Pot sized.

In the example I was thinking a generic villain who's fully stacked or close to it. I realize shorties requires a different approach. And just to clarify, the only time I'd be out of position is if I was in the blinds ... because I'm basically never limping in, correct?

What if the villain bets an unusually high bet amount -- let's say 10bb's. Do I still want to put in ~35bb's and risk getting the post flop pot size out of control? Assuming I've got a good enough hand but not a made hand (something like AK or AQs) to continue with, do I want to slow down a bit here? (I have a feeling this is very villain-dependent.)

Yep.

Around 3-4x initial raise which ends up about the pot.
