op-raise size with antes

[killing_random]

I didn't get an answer I wanted there:https://www.cardschat.com/forum/tournament-poker-59/op-raise-size-ante-484111/

So I repeat it again here:

How should you change your op-raise size with antes?
Is it simply 2.5bb + antes or something more complex?

 

[Collin Moshman]

I'm not able to provide a specific rule of the form: Raise-Size = X bb's + Antes

But here are some thoughts on this:
In practice, most players make open-raise size based on effective stack rather than antes. So with 150bb stacks you might 3x (regardless of ante), and with 30bb stacks you would min-raise.

I agree in theory though that ante size should impact raise size; with a very large ante, for example, good opponents would never fold the big blind facing a min-raise. So the right approach probably depends on the table. Normally it's fine to have a default open-raise sizing that just varies with effective stack. But if there's a bigger ante and players are adjusting well, then increasing your raise size to an amount that gets you some fold equity would be correct.

Ranges should also be varied depending on ante. If there is no ante, or the total ante in the pot is only a fraction of a big blind, then its often completely fine to give big blind a walk, if it folds to you in small blind, and you look down at some trash hand. Whereas if the total ante is more than a big blind, you definitely can not give up without a fight to often. So in that situation you probably want to develop a SB limping strategy, where you then also mix in some "trap" hands. Or you simply limp all your hands.
