Suited Broadways @ 6-Max, 50NL

I seem to be losing money on suited broadway cards and suited aces.

How am I supposed to react to a 3-bet with something like KQs? I know if villain's range is above 10% and hero's stats are slightly laggy, then it's worth 4-bet shoving with aces like AQ, AJ, AT (particularly when calling would force you to play OOP and you're being 3-bet from button as CO, or from BB as SB). But when it comes to KQs, am I just folding to a 3-bet even if the guy has a high 3-bet stat? Usually I've been calling IP and folding OOP. Same story with KJs, KTs.

Also, it is reasonable to 3-bet against high-PFR/high-ATS openers with these hands, right? Been doing a lot of that... I've only played 10,000 hands at 50NL so far...

Hm, feel I need to get a bit more specific with this so I'll just outline my strategy for each hand, and someone can point out where I need to fix up... Bear in mind I play 12-16 tables and run at about 18/15, 6% 3-betting... My ATS is 20%...

KQs...
Open from any position, fold to any 3-bet from 0-6% 3-bet statters, unless I'm on the button and I get 3-bet from the blinds by 5-7%. Fold to any 3-bet if will be OOP. If I'll be IP against a 3-better with more than 10% 3-betting I'll be calling and playing the flop. If a high ATS, high PFR villain opens, I'll be 3-betting in position and from the blinds if they're on the button or CO.
Same with KJs and KTs I suppose...

AJs/ATs...
Same as above really, except if I get 3-bet from a 10%+ and I'll be OOP, I'll 4-bet shove?

AXs...
Yeah, pretty much the same as AJs/ATs except less 4-bet shoving. Almost always folding to 3-bets when OOP. Also I won't open unless on button or CO...

Hm, yeah, that's about it...

I don't understand the abbreviations and stats you used, but the hands you speak of are trouble hands for the simple fact that they are aesthetic, nothing more. I play those hands a lot, I play them different depending on each situation, I don't think you need a standard for this set opponent or that opponent, just do what feels like the right move at the right time. I would advise folding if you have to cold call a 3 bet, but if your the original raiser and get 3 bet, more than likely you're gonna want to see a flop.

dont play hands that do not allow you to make simple decisions if you mass table. Its just not possible to make the proper decisions.
FWIW, KQs is a flat IP for me and OOP its a fold when 3bet by anyone over 5%

Just mash the fold button.

It's not like you're an easy target for light 4bets.

Oh and steal more blinds <30% ATS is a crime, imo.
