wow

I think this is 100% fine
His 3-bet size is very small, we have position and good pot:stack ratio postflop

It`s very different when you open 3bb and someone makes it 11bb - you literaly have about 40% more postflop play here. This is almost the mathematical equivalent of being 170bb deep and making it 3x and someone making it 11x

Also the way he played his hand on the flop turn and river suggests we can crush him postflop with a large variety of hands as long as we have position

If the river was Q through 2 that was not a spade we stack him almost 100% of the time , this is just a very unlucky river

I think if you turn your hand (dat QJo calling 3bet ip hand) into a preflop blocker game, it`s something most players are very adept with these days, you basically lower your edge because you can now be solved very easily via HUD, furthermore I`m sure hes gonna have decent shoving ranges pre given the preflop positions. By flatting you put him in a spot where he clearly had no idea what to do and you gained a massive edge (since his plan was to clearly close his eyes and clock check call any on every street)
