These days many people approximated (and some claim solved) HU limit holdem. I wonder if anyone bothered to calculate how much 3betting preflop is worth for BB.
That is how much more BB expects to lose if they never 3bet preflop (just call/fold vs a raise). Any guesstimate or better yet calculations ?

It's a good question that I often wonder about when playing hu, especially since it's much easier for a human to balance ranges this way. In practice, almost all of my opponents err on the side of spew by cbetting way too often, so I don't have to worry about it too much.

I know it has been simulated, and it shows that if one 3b too much, it loses money. 3b less is not clear to me and it will also depend on how the opponent plays on every street. Using common sense should improve one's ranges.

I do not know the simulations of 3b less, if it loses money or not, eg. some big pair might just call shhu as it is better mixed as a cr or donk, as well as it can see the overcards first, but 3b huhu does not leak as much info, being mixed and vs. weaker range, and against a different post flop play.

Huhu, it is usually likely a mistake to call w big pairs, but even that is not necessarily true, eg. cr at some selected point might in cases make more, but opponent is also less likely to call down such cr as weak as he would call a 3b down, and when ever opponent raise, one has the option to 3b, though after cr one can have the option to 4b, and maybe more safely than when one gets raised on the turn and one 3b it.

Other huhu hands that look better as 3b are two cards ten or higher as they are strong and if they can additionally bully the opponent out, they should all be good 3b, but if the opponent is the usual betting machine but folds flop often after 3b, at least he does not see the turn as often, though it might be like break even, but still further, he will not see the river either, and to prevent that, one would need to cr air often enough, that has also the edge over 3b that one gets to see the flop before putting more money in.

The other edge for that air cr, plus some mere high card cr that also look specific flops before they cr, c, or fold, at some point, is that one gets more mixed w cr, or and donk.

Vs. passive post flop player, who doesnt cbet or ccbet enough, and maybe is more solid, it is my opinion that any ace and pocket pair should 3b, with some bit of same reason as one would cr air on flop.

So, as so, it depends, but vs. optimal bot, one can not find leaks to exploit this way or that way, but still, not 3b all that many slick hands opens more options as the pot is smaller, one gets to see the flop first, maybe the opponent will even check, and even the bot might, that might give one a plus ev free card if nothing else. Not 3b all slick also will make it impossible for opponent to read ur kickers 100% sure.

I think there is a huhu forum for lh.

I think this is an important point that shouldn't go overlooked. Though I typically don't 3 bet 33 or 22 as I think they earn more as part of my calling range. The same logic should apply to the later streets. For example: if my opponent cbets the turn very selectively then I'll check raise the flop more.

Huhu lhe forum is pretty dead.
