...finding a solid default strategy against thinking limpers.

Typically they raise ~40% and limps ~40-45% and is balancing their ranges so I occationally run into limped AA/KK from these players.

In despair I have started checking 100% of my range vs a limp from these guys but still I get into trouble with a bottom/midpairish hand when they bet flop/turn which they also balance pretty well. I know its small pots but still I feel I am getting exploited when I fold a good ace/low pair unimproved vs a turn bet and if i call/raise I feel my range is extremely polarized and gives my opponent easy decisions.

I've tried semibluffing a decent amount but hate myself getting raised on river in a tiny pot on flop.

Any constructive input is highly appreciated.

You should be raising their limps frequently. Yes, you'll sometimes run into a slowplayed AA.KK but your opponent will miss a lot of value the hands that you check. He's letting you see a lot of free flops with your bad hands so make sure you extract value with your good hands.

In the hands where you check preflop, you shouldn't put too many bets in postflop (unless they have an exploitable tendency of folding too much), as the bets you're putting in are more significant compared to what's in the pot.

If they're raising range is roughly the top 40% you'll need to reduce your semi-bluffing post-flop and just give up slightly more frequently than normal, as their raising range is on the whole a lot stronger than someone who might raise twice as often preflop.

Phil, thanks for your input.

Their raising range isnt top 40% excluding a few limped monsters but a very mixed hand selection of their overall playable range. They may raise T6, J5, K2 preflop and limp KTs, JT, A9 etc. and floats a ton of flops if I raise PF.

OK. You might want to estimate the raising range then compare the equity of your standard calling range against that range and against a standard raise-or-fold opening range.

If the limper's raising range is stronger then you'll want to fold a bit more preflop and also change your postflop play up a bit.

But do you hate the idea of checking 100% of range vs their limps given they are limping a very mixed selection of hands?

Its somewhat like MitchL's idea of limping every hand blind vs blind.

Yeah I think always checking is giving up too much equity. If they limped 100% of hands that's a mixed range but I still want to value bet my best hands. I think you gain a lot by doubling the preflop pot when you want to.

I will take a closer look at your ideas. Thank you for posting.

MitchL idea to limp 100% from SB in bvb is completely different. We do not have the toothbreaking positional advantage there like we do OTB HUHU

Having a limper is a great victory, no matter if he's thinking or not. Learn how to exploit them.

What do you think about checking A7-, K7- to cover our ass when we check and the flop comes K or A high. Do we need to be able to represent these cards in limped pots or are we giving up too much value?

Yeah you could do that. In general, though, it seems that raising limps with a v. wide range is the way to go. Your opponent just doesn't gain that much if they limp-reraise and they lose a lot when you get to see a free flop with your non-raising range.

remember if u stay on the attack but dont risk too much in size of the pot u can get the opponent to reveal their hand so u should be punishing a limper most of the time with a 3 -4 x raise and a c-bet of about 1/2 to two thirds of the pot when they call your first bet
Force him to show strength or fold
