Easy fold?

This hand only beat bluffs, and there are only runner-runner outs.
In fact, even if turn and river are it may still lose to a straight flush.

I've learned to fold these.
I'm not a PLO expert though, since I play hi/lo

I would cbet as default but versus aggro check can be fine. Partly for pot control but Its good to understand that big part of value of check comes from villain willing to attack wide on turn. So we also do it for check range protection. Good to point out that BB is supposed to have somewhat sizable lead range in this spot. So if that is the case then his check range is not quite as strong. But yeah its common for people to check too often in BB shoes. Not having pair blocker is reason I often bet with straights though as 2pair/sets are fairly low equity holdings we want to get value from. Its also component to slowplay straight if we are heavily blocking two pairs and sets. E.g. KQJT on QT9r for example.

On turn I would lean toward folding for not having flush blocker and hand being dead versus flush which villain mainly reps. Might also sometimes be higher straight. If villain used smaller sizing then calling.

PS: If flop would be like 865 and we had 97 I would definitely bet. Now board is more dangerous allowing JT9+fd type combos making nut straight way more vulnerable. In real life I think we have higher EV versus most to cbet on this one as well. Yeah sometimes it will backfire but plan should be to just call versus raise and go from there.

I have been thinking about what you wrote. My thought was without any backup/removal I won't be able to barrel on most turns so it checks through and then if villain decides to bet river big I will have 0ev decision. But yeah betting the flop is probably better.

The slow-play concept is interesting, I have seen the concept apply mostly to turn/river where ranges are more defined and narrow. But on the flop I thought the opposite, that is the stronger a hand/hand class is the more aggressive it is. E.g ,on 2-tone board (non-straight), top set + fd bets more than top set without fd. It's probably because ranges on flop are so wide that villain will have so many hands that call. So back to this hand l think even nut straight+top set bets the flop.

On 2 tone flop it depends on the structure. Like if we have A♥:K♥:K♠:5♠: on K♦:4♥:2♥: flop it can be very reasonable to check. We block everything very heavily. Plus 42 rarely give 2 pair or set to villain even if he is on BB

But if we have same AKK5 on K86 there is now way more stuff that are able to continue versus cbet and we also need more protection.

Another classic spot could be paired one. Having KK8x on K88 is very good slowplay. But if we have KK without 8 we likely want to bet very often.

Another complete overkill hit could be like AKKJsshh on KQTssh flop. Hand is absolute monster but chance we get fold with half pot cbet is probably more than 80%.

But indeed on this flop we have in this hand there is really no total overkill hits as there is just so much going on in. Plus with high SPR we simply need to build pot in position with very strong hand. If it's 3bet pot with lower SPR and flop being bad for our range it becomes very different scenario.
