The last few weeks I've had some time off work and I've been playing a bit earlier in the day than I'm used to. There's a ton of OMCs playing at this time.

One in particular seems to be a regular and has been there almost every time I've sat down. He plays super tight (unsurprisingly). He barely sees a flop and I've only seen him show down QQ, KQs and JTs so far, and the JTs was in a limped pot with a lot of callers before him.

The other young guys at the table all play really aggressive pre. They open a lot of hands, steal a lot, and 3-bet a ton.

The thing is, I haven't seen old man reg fold to a 3-bet once. He just flats with what I assume is his whole range.

I know 3-betting a lot is generally recommended against OMCs, but based on my experience in the past few days it looks like I'd just be building a bigger pot with a much wider range than his if I was to 3-bet into him, so I've just been flatting.

How would you guys handle this? Do you adjust your range to include stuff that plays well against a really tight range and then just call in position a lot? Or are they others playing correct and I'm missing their reason for 3-betting? Also do most OMCs play this way or have I just found one that likes his pre-flop hands a bit more than usual?

Why do you assume you are supposed to 3-bet wide against OMCs?

Strongly disagree. I generally fold to OMC raises. Attack their limps, not their raises.

+1. What's this OMC's opening range? If it's ~QQ+/AK, 3betting wide against that is suicide. You have zero FE preflop, and you're creating a low SPR spot where they can correctly plan to stack off postflop with TPTK+ 100% of the time. Fold to their raises, unless they're the "never fold an overpair" type, in which case you should be able to setmine profitably assuming effective stacks are large enough.

EDIT: If his opening range is noticeably wider than QQ+/AK, then he's not really an OMC; he's just an old man who happens to be drinking coffee.

Also be careful about OMC's cold calling range vs 3bets.

Last week I squeezed with AJs from the BB over an UTG+3 open and a pile of calls (including OMC in MP). I cbet on an A83r board and OMC min-raised.

Easy snap fold.

OMC showed the ace and it was painfully obvious he had to have AK.

If I'm playing w/ an OMC, any sort of preflop raise I'm out (cause they barely, if ever do it). Post flop, any sort of raise at all I'm also out unless holding nuts. Also, if in position, I'm more likely to check back on a bunch of boards if playing an OMC. Don't need them check/calling down to the river or bumping you with a raise at some point. You know you're probably toast then

Try to get to his right so you can have the btn more often.

I'll open wide against true OMCs, but I literally have almost no 3! range against them.

I've played against a lot of these OMCs for a large enough sample size to find out that many will open AA/KK, and that's it. QQ/JJ/AK/etc., they limp. I used to always fold to their opens, but after a while l realized that some of these OMCs will never lay down their big pairs post-flop unless there's some obvious 4-flush or one liner on the board. Combine that with many of these OMCs only opening to 3x, and I've now adopted a strategy of calling their opens with a lot of mid/low suited and connected types of hands as long as we're at least 100+bb deep. It's super easy to put them on a hand, I see a flop for much cheaper than a normal open amount, and I'm getting their entire stack almost every time I out flop them.

Against the super-tight OMCs that do have a fold button post flop and can get away from AA/KK, then I too usually fold pretty much my entire range against their opens. To play a pot against these types of Vs I'm looking for the ones that wait for AA/KK and then are going to the river no matter what, and even then I'm usually not playing broadway hands against them because they usually dominate that range.

There's a few OMCs who play in my game who play similar. Very tight range and they don't raise/reraise anything (literally anything, including AA) preflop. They are also very aware of their nit image (and know that any raise they do will scare away all their action). Playing aggro against these guys is simply handing them money, imo. I think they are too passive when shortstacked (which they often are) and are missing out on lots of opportunities to steal raised pots with decent hands / should be getting in shortstacks preflop with good but vulnerable preflop hands, but overall it wouldn't surprise me at all if some of them were slightly winning players due to their opponents reacting to them (imo) completely backwards by playing too aggro against them.

Instead, I play very passively against them preflop and simply overlimp to try to get into a hand for cheap and hit a better hand postflop (where they often have a hard time letting go of their well disguised overpair). And if they happen to be the lone caller of my preflop raise, I cbet air far less often, size my cbet far smaller, and shut down immediately UI if called. And of course never pay off a postflop bet.

Playing pre-flop against OMCs is easy. If they raise, fold unless (i) you're at the very top of your range (KK+) or (ii) you have a nice speculative hand and they're offering you implied odds. 3-betting light is crazy against someone who is only opening QQ+/AK pre.

can you please explain why?
