Hands strong enough to limp but not call a single raise?

[blopp]

Im not limp folding for single raises in plo.

very very rarely I will limp along in the CO with a junky hand like A237 suited to the ace if there are limps before, and I will fold if the button pots it and everyone else folds, but that's about it. Since other players don't limp/fold often this doesn't come up to much, but it's still in the playbook.

sometimes I limp a weak hand like 4589ss in the first couple of positions hoping to get a multiway pot with some bad players, then if a decent player who has position raises and everyone folds I fold.
