I have a question i've been thinking about, for a week or so.

It's an adjustment i came up with about a week ago or so.

If a player is flatting more than 65%, i've been thinking, would it be profitable to tighten up your flatting range a bit?
I usually flat about 35-40 % and 3bet 12-20%. Obviously K8s is an easy flat against any villain most of the time, but stop flatting hands like K7o, Q8o, J8o etc. Poker theory in any game is that, position is top 3 of the biggest factors by far, so i'm thinking, why play marginal flatting hands when you opponent is going to see the flop oop so often?

If your opponent flats a big percentage, you should adjust your opening range, not your flatting range. You should tighten up your opening range and start limping more hands against these players. Your flatting range and 3betting range should be adjusted related to his opening frequency.

Surely whether we tighten up or not depends on how they play post flop. If they fold to cbets 50% of the time would you still tighten your opening range?

Of course not, he asked only about preflop tendencies. If an opponent flats a lot pre, he most probable will have a low fold to cbet percentage

+1
also the hands u mentioned will have better result than folding in the long run against most ppl.

Because it is more profitable than folding them. You can do your own work on this in poker tracker or holdem manager. Position is important obviously, but Poker is all about winning the blinds, and when there are only two players, if you fold to often, then they can exploit you by raising any two on the button.

Improving post flop skills is better than folding hands to compensate for poor post flop play. A huge leak in a lot of micro players is they are to passive oop.

Their flatting ranges has no relevance to your flatting range.

Openraise with bigger size?

65% BB defend is close to what average population has, isn't it? You can still open wide against that(some'd say 100% wide) - your hands still have equity, and postflop fold equity makes you profit, too.

But if villain is very stubborn both preflop and postflop(on all streets), you can make some adjustments, such as raising tighter, with a bigger sizing(both pre and postflop), but also barreling wider for value than you'd normally do. With mediocre holdings, if villain is letting you, limping & taking small pots can work well.

I find that 4x'ing gets a lot of folds!

barrel more

Calling 65%+ is bad and will be exploitable against a good player. My first thought is that if he is calling this wide pre he is probably rather sticky post flop as well. If the villain is really sticky OOP and also raising a decent amount from button, I DEFINITELY LIKE TO KEEP POTS CONTROLLED. I find that against these types of players my two main adjustments will be min raising a tighter range from the button, and depending on how often he is opening from the button, I may open my big blind calling range.The hands I'll begin playing more from the big blind will be playable hands like suited two and three gappers, high card suited hands. Basically the bottom of my range against a tight opponent that I'm folding OOP I would begin to call with. I would be veryyy selective and not overzealous flatting OOP tho, I'd like to emphasize that. At all points in the match I'm looking for the opportunity to control the pot and pot size. I want to play as many pots as possible against this opponent and avoid bloating pots early game if I can. I may even start limping my middling hands if I'm running bad to start the match, combined with him being aggressive or sticky in pots that makes bluffing and semi bluffing less profitable for me. These types of opponents are making too many mistakes over the long run to allow yourself to bloat pots and not realize your edge. ALSO CHECK BACK A LITTLE MORE. Someone tell me if my strategy is flawed lol. BTW obviously WHEN YOU HAVE VALUE like a semi decent top pair against this type of player we are taking the train straight to VALUETOWN in and out of position looking to maximize value whatever way we think we can.

5x them, 4x is so yesterday

i believe the current standard is 2x, and i don't recall any of these proposed manly betsizes to be ever used yesterday or any of previous days or years for that matter

True, always good to have a mixed strategy

OP plz dont listen to them, they are just trying to troll you. Below 25bb you should just be doing the standard 3xing with the bottom of your range. 3xing with hands like 24o will give you more fold equity and reduce his flatting range

Hope that helps!

work on your troll game son. i could smell that reverse troll a mile away

i will not be a dick like these trolls above and give you real secret code which you will have to decode yourself. it starts with letter and 2 number. Ok, secret code is: t45

99 is my favourite preflop raise size - I like to play power poker!

this

Depends on how often he 3bets.
1. flat 65%, 35% 3bet:
against this kind of maniac you want to definitely tighten your opening range. I would fold junk pre, mr all my good hands+marginal high card hands (K2,Q3) that can easily fold to 3bet, and limp connected cards. Adjust from there
2. flat 65%, 0% 3bet
play every hand, mr value range, limp mid and low and stab at flop, your goal is to play/steal small pots.

You also have to figure which range he flats with. Keep in mind that a 65% flatting perc. cannot continue on that many flops.
See how he reacts to barreling on turn if he flats too much on the flop.
