1. Please identify the several points in my post that are directly contradictory... Being unbalanced with your oop 3-bet range is exploitable- we agree on that. You suggest balancing by being more aggressive oop and I suggest doing it by being more passive. I personally think being aggressive (pre and post) oop deep against a good player is fundamentally bad/the road to ruin. I could def be wrong and I obv respect your opinion quite a bit, but a billion hands played and watched deep + tons of time thinking about it/discussing it with good poker minds + jimmyvjv's and clorox's posts have me liking my side quite a bit so far.

2. I'm a winning player and I play passively oop (against good aggressive players). I don't know much about jungleman other than people say he's the best hu player in the world and apparently he plays passively oop if the stacks and opponent call for it. Come to think of it, all the best/winningest players I know play passively oop against deep aggressive opponents- especially pre...

3. Just because I'm flatting pre and checking the flop (usually) does not mean I'm "check/calling the whole way and guessing" and losing the battle. I'm earning value by being underrepped/inducing bluffs and thin value attempts when I do go that route. I'm also not going that route every time at all. I'm going to c/r for value/as a bluff/for protection/etc a decent amount on different streets, putting my opponent in a bad spot (instead of the opposite). I'm also going to lead occasionally in certain spots on certain streets and fold when my hand figures to not be best/I don't like the prospects of continuing. In general, I really like reacting to the guy I'm playing against, not vice versa...

4. I like controlling the size of the pots I play too. I make them big (with the potential of becoming huge) ip and keep them small (unless I really like it) oop.

Looking forward to your reply.

In one of the leggo poker tips given during the twoplustwopokercasts,
I remember hearing aejones advocate flatting oop with your
entire range when playing greater than 250bbs and playing headsup.
This isn't headsup but I don't think the situation described here is really
that much different, if at all (oop and very deep vs a lp opponent with a
very wide range)

My 3bet range will be stronger, but my flatting range will be much wider. So the lag can't (or shouldn't) be firing away with air on very many board textures. On a low dry board, when overpairs don't make up a significant part of my range, a lag would be crazy to value town lightly when my most likely hands are either c/r or c/f. Contrast this with a 3bet range (and a bigger pot) that the lag might think consists of ui overpairs, non-flush/straight hands, etc. and his bluff frequencies should go up. Which brings me to the next point...
It's hard to flop a good draw and if the lag is planning on calling a lot of 3bets ip after raising atc then that means he isn't always going to have a drawing hand. Even hands like J7s don't flop draws often. So if he only bluffs on really scary boards for ui overpairs, he is going to be just folding the flop or turn a lot. You could easily play 7 or 8 pots like this where the board isn't conducive to bluff ui AA, or where you don't flop a draw or made hand. Now if you decide to start floating and repping draws that come in that's another thing, but that would mean your bluff frequencies are going to go up to the point where it's profitable for the 3bettor to c/c and induce spew. If you don't bluff enough and your value range is only 2pr. +, then the 3bettor can easily fold ui AA and you will really be in trouble.

When you are really underrepped oop it forces you to take a c/eval. line with that range ui. Flatting AA is fine pre, but then you are handcuffing yourself on a lot of boards. I mean, we aren't going to underrep pre and then massively overrep post when stacks are super deep. Underrepping also means that we have a hard time releasing on dry boards. If the lag can value bet most of his overpairs we are almost forced to call with AA even though his range is almost atc. And those times we flop big, like top set, we can never fold even if an obv. draw comes in and he goes bananas.

If the lag doesn't 4bet we can 3bet a really nice wide range (so long as we avoid hands that make second best a lot). This makes it a lot harder for the lag to use his position since we can rep. a ton of value hands and even a lot of bluffs too. We also get max value from his atc openings by forcing him to either fold pre or continually take a flop with the worst of it. If he has no 4betting range, that means he is flatting with AA/KK and we get a chance to put him in a spot where he is massively underrepped and our range is wide enough to make things very difficult and he will pay us off a lot or miss out on value because he can't go nuts with ui AA on a lot of boards. The downside to this is that we will sometimes be in spots where we will be forced to valuetown ourselves (like 3betting with QQ against the lag's KK). But this is the lag's constant dilemma and it doesn't happen enough to make it unprofitable for us to stop 3betting a lag who never 4bets. Being oop doesn't affect us exploiting a polarized 4bet range. We will now easily be able to get the proper stack % in pre with AA and take a passive line to induce bluffs with KK/QQ, etc.

The cooler thing is very important imo. There are just some situations where if the pot is big enough you cannot fold. Coolers happen to everyone, and I would rather my good ends be in 3bet pots where I have a shot at getting all the dough in.

Edit: Good discussion, and I'm kinda playing devil's advocate somewhat since super deep I think everything goes out the window and you just have to make the play that will win you the most money without exposing yourself too much. Against a worldclass lag this could very well be flatting everything oop. Against a good, but not great lag, I stand by my arguments to 3bet. I also stand by 3betting when <200bb for sure.

getting to this thread late and I haven't finished reading thru all 8 pages yet but I'm immediately leaning towards this as well.

I don't like moving in with only an overpair because while your original description of villain sounds like he might just call with any kind of draw, your layer revisions to his character suggest he does have the brain to sniff out a trap. by c/c'ing we let him make his moves with a larger part of his range. if he's smart enough to not call off his stack but is more likely to utilize his stack as a weapon with a range that is > than the range which he calls with it seems like you'll have the best of it more often when villain sets the pace, lettin him bet into you. BB's stack protects you more IMO. villain can't think he can push you out so that at showdown he loses to BB instead of you, and in that scenario I can't imagine him wanting to setup a side pot with air after BB shoves turn.

to me this makes the turn the most critical juncture: do you pop over top of BB? which again I don't see a lot of value in unless we are sure villain is likely to want to create a side pot on the river, which even a maniac should be unlikely to do, and given your revised description of villain, your only value is gained from what villain puts in to pot.

obv turn card could change your play but I think our only option is letting villain valuetown himself and making a move on the turn will only give him more o an opportunity to realize he has a fold button.
