Overlimp and Isoraise Ranges

I believe I’m losing value because I don’t have a good overlimping range. I’ve learned on 2+2 that overlimping is usually bad because it not only caps your range but also exposes you to an isoraise from later positions or the blinds. So I’m much more inclined to punish the limpers than join the loose-passive party to the flop.

But when opponents veer from GTO by limping—they play passively and also too loose or too tight—how should the hero adjust to exploit them? For example, in the CO facing one limper, Red Chip GTO suggests isoraising the top 11.5 percent of your range. 10.4 percent of the range are “optional raises,” 8 percent “acceptable overlimps”. It has you always iso-raising with A9s, A5s, and A4s and accepts overlimping with A2s-A3s and A6s-A8s.

Of course, few regulars play GTO. So consider an isoraise or fold strategy in the CO if the BTN or blinds are aggressive. Overlimp if the BTN and blinds are passive. Overlimp wider following two limpers. The deeper the stacks, the more you want to overlimp wider with nutted hands like Axs, pairs, and suited connectors. You also fold more trouble hands like QJo, KTo, and KJo.

I posted a hand history where I isoraised over three limpers on the butt.... Only one-third of the twenty posters favored the isoraise. Over two-thirds favored an overlimp. I’m now trying to learn from those two-thirds who favor an overlimp.

Other suggestions on how to exploit limpers by overlimping?
