NL5 Zoom Q2s BB vs SB

Pre ok. Flop ok, we get called by Ax, PP, so we go for value, ez (maybe we can go even bigger). Actually now that I think of it I think polarized bet is ok, so Id go with 60-80% pot bet. OTT on the other hand I would slow down, T is scare card for PP, so part of those will fold (without spade lets say), also flush is completed which is pretty scary as well. I would bet 1/2, not 2/3. I don´t think ppl will put you on 2x there often, so he basically thinks u got Ax or flush. I don´t think ppl raise there with intention to fold out Ax. What he could do is to shove his Ax with spade, that´s what I can see happenning, but only from aggro players. So if he is aggressive I call, if not I fold. Also he definitely has TT as well as Ac2c, so you might be dead already.

Preflop and flop ok but turn what are you hoping to beat ?
I'd maybe even not second barrel in fact so much that board is scary. You don't have 3 barrel vs most Ax on it.
When he is check/shoving it's always a flush (or some few Ax with spade indeed).

I don't play zoom, but I'll give my two cents.

I know that stealing and re-stealing the blinds on zoom is a move you have to have in your arsenal, especially when it's folded to you. You had position, decided to 3bet to 2.7x, it's "ok"...
Calling would be terrible.

Flop just go bigger imo. Half pot is two small.
Turn I see no problem with betting again, but when he raises you should really consider. I don't know the players on NL5 zoom, but are they capable of shove-bluffing this turn? Do they do this moves with strong aces?

If they have the hability to think of a hand: "the ace OTF favors his 3bet PF, he cbets the flop and the turn with the 3rd spade out there. He's either a dumb or has a decent hand. If I shove my flush he's probably calling and I win a big pot!".
If they don't think at all: "He's just trying to tell me a story, but I'm going all-in on this turn to make him fold".

Act in accordance with the most convincing of the two
Now seriously, the question here is to know if they're capable of doing this with an ace.
The problem with this spot is that the ace also favors his call to your 3bet OOP and the flop cbet. So it's probable he has an ace with a good kicker and thinks he's ahead.

Overall, I'm mostly check-calling the turn.

Sux but i am calling this off. Sometimes he would have the flush but sometimes he would have AT and Ax with a strong spade. If the guys is fishy he would sometimes have a weaker deuce (optimistic though). Give him a range of few flushes like KQ/QJ/JT/67/78/9T and give him Ax:Ks:/AxQ:Qs:/Ax:Js/AT. Sometimes he would also have TT and AK with no spade, calculate your equity against this range and see if the call is mathematically correct

Please do not check/call the turn. Just dont its awful. Every weak Ax would check behind and you lose value. You also give free cards to every one spade holding there as he has a lot of pocket pairs that call the flop like 77/88/99/JJ. If you check the turn you will end up calling vs his better holdings that beat you and the rest will be checking behind so you lose value.
