First night playing in a while. 100BB effective stacks.

I get [Ks] in MP and raise it to $11 after the first 3 players all limp, folds back and they all call.

Pot $47 and the flop is [9h][8h].

Checks to me, I bet, utg checkraises strong, folds to me, I instashove.

Of course there's no other way to play it ... is there?

UGH..i kinda don't like it. This is FR so i expect players to be more nitty than my average 15/12 opponent. And that is kinda not good. Basically if I decided to CB this flop i must be willing to shove here. Some read on villain would be great. Is he a type (I'm not such exist in FR) that CR every monotonous board vs you? Does he overplay TP?
I kinda would like youto bet more PF. I fear domino effect and 4 way pot w hand that will always suck post flop. Also I really dont want callers behind me at this point. Especially if I have no reads on the table. I'm not sure what they limp but on this flop you will be often be against flopped flush, 2 pairs or sets. Only hand that I can see him having here that you are ahead would be some KQ w Qh or something. Pot is smallish so unless he CR light into field of 2 players yet to act(they could also be wanting to CR the PF raiser, he cant know that for sure) I don't think you are ahead often here. So pushing would be spewing, esp. I guess @ FR.

I think you can bet a bit less on the flop, but basically I like everything you did just fine.

Its FR so the guy prolly has a set but you cant fold at this point.

Why bet more on the flop? I want people to call with just a big heart.

The only reason to bet more is so someone doesnt try to bluff raise you off of your hand, but in this case, Im not folding no matter what they do and besides, People dont bluff check raise boards like this.

Hero most likely has the best hand and best draw (with few cards that can outdraw him) so i think its better to bet a little less than a little more.
