Hello

This hand is from a €110 live tournament yesterday.

Blinds 400/800 ante 50 8 handed

folds to CO who limps 800, i have J 7 on BTN and decide to limp along just to get involved cheaply as ive been quiet a while (bad excuse i know but it happens) SB folds and BB checks.
Stacks: BB 80k CO 70k Me 60k

Flop: K 9 10 (3200)
BB check, CO bets 1000, i decide to raise to 3200. I think this is great hand to raise with here with double gs, backdoor heart and straight blocker in position.
BB calls this raise and CO folds.

Turn: K 9 10 5 (10600)
complete blank turn, BB checks i bet 4600, BB calls

River: K 9 10 5 A (19800)
So i miss my gutshots but have both straight blocker and heart blocker, with this in mind i decide to bet 12000 into 19800.

Thoughts please on this play, will update result afterwards.
Thanks

Fold pre. As played you have some equity but this board should have connected with one or both opponents limping ranges. You'r only folding out one pair Kx hands with a bomb otr and sometimes villain looks you up with that anyway.
There's no point posting the result. Maybe you got this through on this occasion but that doesn't mean it's the correct line and it actually definitely isn't with that limp pre.

Thanks for reply. Id like to hear more though about why you think this is such a bad line. I agree completely the best play here is fold pre flop, but once the flop comes, i actually think i have one of the best possible hands to bluff with. In addition to my own hand, it seems pretty unlikely either of my opponents would be as strong as QJ pre flop given the action, made less likely by the fact that i have a J myself. So im really targeting one pair hands and even two pair hands which are going to be facing a really tough spot on this river given how ive played the hand. Again, my 7h makes it less likely opponent has made a flush, and i could certainly raise the flop with a flush draw, maybe a pair and flush draw like 10 7 hearts for example.
I think i can really credibly represent both straights and flushes here with this line, so any other ideas as to why its bad would be greatly appreciated as in my mind all looks good!
thanks

My main issue is with the limp pre. I don't play these stakes and assumedly more players are thinking through their decisions as compared to the lower limits. I don't think your line post flop is necessarily bad but limping into pots and then getting creative with J high multi way against unknown opponents isn't going to be +ev imo. Villain has played the hand like either a one pair hand or a draw and the river card completes a lot of those draws.
