Preflop you can mix between the call or 3bet.

Flop I prefer a x/c here, and maybe x/r turn on a spade. Or x/c if we make a pair.

Really looks like we got lucky that opponent probably folded a QT here once they check back turn so I'm not sure I love the riv bet as our line doesn't make a lot of sense. And we have showdown value vs the QT. (QT will likely call the raise given the sizing)
What do we x/r on the flop? A set or 2 pair maybe. But it's a little dry. And when we check the turn it looks suspicious.

Just wondering why you think the flop is a good x/r?
I think it just builds the pot for not much reason at this point with no immediate draw.
And that's my main issue with how you played it here really.

I see you're obviously experimenting with these plays which is good, I guess just need to really have a sure reason behind it.

I think I'm just calling with this hand on this texture. Two overcards with backdoor NFD makes a great float.

Raising will probably be +EV, but what is your plan for turn barreling? There's only sets and QT which is ever raising here, which is a narrow range considering that QTs isn't a standard defend from the BB versus an UTG+1 open.

Not sure about the river bluff. I'd expect you to get called by his Jx combos when he's closing the handout. There's nothing wrong with giving up on the turn when your barrel cards don't come. Not all of your flop bluff raise range will continue barreling.

I also vote for just calling the flop here. Backdoor spades are obviously great to add to your bluff raising range but AQ also has some showdown value. Besides, your outs are also potential barrel cards for the villain which is important.

Middle card pairing the board is one of the worst ones to barrel on and I wouldn't continue with my bluff once it hits. I don't think your river line makes much sense once you checked the turn.
