I suspect the competent player would be betting a Jack here on the flop to induce the jam of QQ+ but a larger 3B PF might get this hand out of there. AJo or KJs is what I suspect the Villain leading to have...

I would tank and finally begrudgingly call.

Then shove any lower non spade on the turn. I would fold to a spade turn and big bet.'

I want him to make the mistake of putting most of his stack in the pot when his equity has shrunk.

I like a jam here. I think it would be a huge mistake to commit half your stack and then have to fold on a bad turn. With SPR this low you can just gii against both opponents and let the chips fall as they may.

Given description of V2 as a solid reg it's tough to put many JX hands in his 3b calling range oop. Also I would expect a solid reg to be capable of leading out more than just his few JX hands here so that + SPR = ship it in

No basically saying that the mistake OP made was not 3b enough preflop.

More or less this.

I'm never shipping the flop because
#1) I fold out a ton of lessor hands I beat, (garbage underpairs that put me on AK)
#2) I would rather peel off a non-spade turn and force the FD to get his money in when 1/2 his equity has been cut out from under him
#3) By merely calling the flop lead out, I allow V to make more mistakes on the turn
#4) BY calling the flop bet when in position we allow ourselves to gather more info about both villains and use our POSITION to exploit both

In general, whenever I have a really strong hand and I'm in position and a player blasts the pot in front of me on the flop, I prefer to just call. Because of position, Villain will cut his own throat for me, so I can just sit back and let him do the work. This keeps his range wide and allows him to continue his aggression with a ton of lessor hands.
