Was more on aggressive side in this tournament, we haven't any history but my table image was probably a bit like LAG.

What you think about my line, fold river? who would play diferently,who would cbet flop, then check/call once fold river?

I think he should have here more bluffs in his range that value hands, but in reality not sure if he plays bluffs this way, or 3barrel bluffing, so I guess I lacked here a bit of discipline by making a call... not to say that it's so close to itm

Why do you check flop there? Just cbet/fold on the flop and get done with it. No reason to go with 1 pair marginal kicker before bubble

Feel more comfortable check/ calling here twice than barreling twice, but agree with you, probably its one of worst timings to do it
