Villain 1 is playing close to 100% of his hands, not folding much postflop until the pot gets big.

Villain 2 has limp/reraised twice, one time he showed down QQ. Overall seems pretty tight

We are $950 effective

V2 limps UTG, I open 75 to $30, V1 calls, V2 plays with his chips like he's going to 3bet and then calls.

I should not have opened this hand after V2 limped, was trying to play lots of pots with V1 but better to just overlimp given how often he was limp/3betting

Flop: K57 ($90)
V1 leads $50, V2 makes it $140, I think and flat, V1 flats

I'm pretty sure I should just 4bet here, I doubt V2 flats KK pre, definitely doesn't have K5s/K7s, so he should just have 2 set combos and probably will raise wider than that. V1's lead is going to mostly be draws and medium strength top pairs, which he may fold to a cold 3bet on the flop, but he might not.

Turn: 3 ($510)
Checks through

V1 has a lot of draws and this card hits him in a couple of ways, but our hand is really vulnerable... Bet/folding $300 seems good rather than checking
River: 6 ($510)
V1 leads $200, V2 folds, we....

This is a weird spot bc the runout favors the loose players range here, I think if V2 is capable of semi bluffing V1 on the flop or even just raising some KX hands then you could come in for the 4bet.

AP do you think he could be value betting some worse 2 pairs? his range is so wide I'm not really sure. Idk what his bluffing frequency is, I know he plays a lot of hands but if I saw some showdowns of him firing some rivers with air I might just want to see it, if you don't put him on spades, you really only lose to 4X combos, I think pot is 510 + 200 so you'd be putting in 200 to make about 700, roughly 3 to 1 on a call I think

Pre is a pretty big mistake imo, also assuming you are in EP or the latest LJ.

Flop is fine.

Otr we have AK, 75s, some flushes, and trapped sets otf. Pretty middling in our range distribution so i think either option is ok, def not a snap call but not a snap fold either. Id turbo muck AK though, though As we can consider bluff jamming

preflop raise is better than an overlimp imo, but both are worse than folding.

flop should be a 3-bet and fold to more action I think. Something like $300. You block them from having sets but if more action is put in you can be sure you're up against one or better two pair.

As played on the flop river is a snapfold.

Pre is cool. Flat flop. Bet turn. AP riv is close, I probably call this kind of player/size.

I'd fold river - I don't feel like he's going to bluff much into 2 players on a 4-straight/3-flush board and I doubt he would bet any weaker two-pair or any one pair hands.

If we're only behind two combos on the flop then just raise/GII.

Kx is going to have a hard time folding given he blocks top set. AX draws are going to gamble it up at SugarHouse.

Bottom two is not a hand to slow play on the flop. Turn is good example why.

Can someone explain why flatting flop is better than coming over the top? I can see merits for both but can't articulate to myself why flatting might be better.

It's not.

OP as you already know, mistakes made on most streets (IMO).

Almost always a muck pre. Overlimp only occasionally here in the right game conditions. Similarly raise very rarely and in the right conditions.

Wish we had more reads on v1 post flop betting behavior. With the info we have, make note of a likely dynamic between v2 and V1, whereby v2 is looking to exploit v1's looseness and raising frequency. Given this I expect v2 to mostly have a made hand otf, most likely of which is a good king, given we block 7 and 5.

I would have minraised flop for this reason. V1 is still wide at this point and may come along for the ride.

After that a turn check is probably best. As played OTR I'd need more reads on v1 because it's close. Either a call or a fold. If no reads on his post flop betting are to be had I'd call it off getting almost 5:1.

it's confusing because you didn't give the positions of the players, but assuming you are playing against the blinds i would go ahead and shove the flop, you have a ton of hands you can do this with including bottom set and nut flush draws...it's kinda deep to do that but we have some hands like bottom set and gutter plus spades that we can also shove. this should actually be the weakest hand we shove but when we are called by naked flush draws we are far enough ahead. never afraid of a better hand here and it adds value to the times we actually have 98ss or something and fold out better flush draws

also, people will hit the call button with Kx, putting you on the flush draw

as played it's a fold imo
