Don't post here often or even play much, but just wanted opinion on this spot. Sorry for sloppiness, will try to make legible.

First hand of match. Villain is 54% ITM according to prolabs.

I get AQ off and am min-raise guy so raise to 40

Villain raises to 140 then I re-raise to 320 with intention of calling shove, but V flats.

First hand we're even so both at 1,180.

Flop is nice and is Q3T with two hearts. (640)

Villain checks and I bet a lot (400) I guess to force a flush/straight draw to shove or something and V flats (1440)

Turn is a K clubs so Q3TK is board and Villain checks...... So now what? It completes draws, pairs AK and makes flush draw with K hearts good. Shut down or shove? Still have 780 left if I decide to shut down, but could be drawing very thin if called.

A shove I would think only getting called by better. Maybe Ax hearts or QJ only

Looking back, I think its better now early in the match to flat the 3-bet even If I think someone is 3-betting light.

Putting spoiler below, hopefully it works out.

you got villain to call a dominated hand preflop and c/c a big bet with 4 outs on the flop, basically committing himself to the pot. why does this lead you to the conclusion that you should have flatted pre?

I guess maybe, being results-oriented, haha.

I guess in general what would be best here? Especially considering it is the first hand of the match, which is mainly why I ask. Just thought I'd get some opinions. Thank you for your response.

why did you think he would 3bet light?
in case someone is 3betting a wide range, getting it in with AQo is fine in general even with those stx. in the first hand however i would most certainly make it 60 preflop because you have a strong hand. this would make it a bit easier to proceed.

Mainly based on it was min-raise, which can read weak. Duly noted. Thank you.

Shove pre or 4bet bigger to make your life easier on the flop.

Depends on stakes, but 4-bet jamming pre is probably fine at 2$-10$.

fyp

this. 4bet is definately too small, especially if its a value raise.

Grunch.

Barring reads I like flatting the preflop rr to 140 for precisely this reason. Plus the benefit of keeping in dominated aces that probably aren't going to be flatting the 3b but will pay off a street or two when an ace falls.
