This was a hand played between 2 of my regular opponents. It got me thinking as I found the way these 2 players played the hand unusual and unorthodox. I would like to know what you guys think of their play. The blinds were @ $2/$2, in a home game.
There was a limper upfront and the CO, a rather loose stealer who liked to call down aggressively, decided to raise to $10 with an effective stack of about $480. Let's call the CO player J. Let's call the OTB guy W, he had J covered. He's a rather sound player but with some leaks. He decided to 3-b J to $30. J elected to 4-b to $90. W thought briefly and called the 4-bet OTB. Heads-up OTF of T♦️9♦️3♦️, J c-bet for $100 into $186. W went into a mini-tank and decided to shove J for his remaining $292. J tanked for several minutes and called off. W showed down A❤️Q♦️, J showed down Q♥️T♥️. What should we learn and not learn from the way the both of these opponents played their hands?

The doubts I have:
1. Is calling a 4-b with AQo OTB a good and standard play against a loose stealer and aggressive caller like J? Wouldn't AQs be a better hand to do this with since it has more playability or is AQo sufficient in terms of high card value? I would usu think calling a 4-bet with AQo is kinda toast against most decent 4-bet ranges, but against this particular opponent in this kinda aggressive dynamic, is it +EV?
2. When W semi-bluff shoved with his A♥️Q♦️on this flop texture, is he really making money from this play? Would having an A♦️instead in his hand be a better candidate to make such a move, or is this a suitable hand to make this play? When both of these opponents tabled down their hands, W made it seem like he soul-read J and applied correct pressure on his opponent and almost made him fold his hand. But like I had mentioned, J was an aggressive caller, so I'm not sure if W had really made the correct play in this dynamic. What was he really expecting J to fold? He only blocked QQ and AA, but hands like Kings with the diamond, or Jacks with the diamond, or even A♦️K♦️ were not blocked and would definitely not fold to the shove anyway.

Please me know what you guys think. Thank you.
