Cash Game - Bet Sizing

for live i'd throw gto sizings out the window, live plays much bigger than gto, it's not unusual for a standard open at a 1-2 game to be $20

I used to have a standard opening size, but long ago i realized that was stupid, because i was specifically avoiding playing against the rare tables and players who could exploit that, and correspondingly, even if they're at the table, they are unlikely to exploit because they don't want to get into an unnecessary war, sure i'm telling them i have a premium which could help them get max value for set mining, but at the same time, they're also of the "oh he has a really good hand I should get out of the way"

i never open limp

i limp behind sometimes when i have speculative hands or hands that hate life playing big pots

my weak hands I'll open around the minimal the table does, if a few players open to $10 sometimes, i'll do that with my weaker stuff like JTs and open to whichever amount is the most which still gets 1-2 callers, which is usually about $25 at a 1/2 or 1/3 table

and then, if there's a bunch of limpers, i'll add on about $5 per limper - this helps keep you honest and stops you squeezing with hands like QJ, yes it's better than the wide range of all the limpers, but you'd rather limp along with the 6 other limpers than you would raising to $40 to $60 that it would require to squeeze

Normally flop = small, live small = 1/2 pot hu, mwp = 1/4-1/3. Such sizing gets thrown out the window if there are fishes/whales, you will need to bet gigantic to charge them for value.

Turn = big, somewhere 3/4-pot-overbet is ok? We can also bet small to cap opponents ranges if turn is a board changing card.

River = max value, bluffs mix. From small to gigantic overbets. Very board dependent, villain dependent.

Say you want villain to fold his missed draws, you have a non showdown hand you only need to bet super tiny, he'll fold everything he doesn't have showdown value as well.

Say you want villain to fold his top pairs and such, you might have to overbet shove.
But then again, such thing might not work on a fish. A fish might snap you off with anything, if that's the case, go max value with your value hands and overbet shove whatever value you have then.

Then there's thin value, I see alot of lags thin value betting small on rivers and profit alot.

At the end of the day it's very villain dependent. Never use normal sizing vs fishes/whales.

It depends. Just from the two responses above, you get a small taste of what it depends on. This isn't really an answerable question. I'm going to lock this up as being to general to make for a good discussion. These types of threads tend to lead to folks talking past each other a lot.

Please feel free to post questions about bet sizing, but much more specific ones.
