6 max plo 100/100/200/400
I am BB with AAK6ds something like 26-30k in stack.
CO folds, BTN raises to 800 - huge passive fish has like 40k in stack, SB calls ( nitty postflop, loose preflop - 40k in stack ), I pot to 3800, first straddle folds, second straddle folds, BTN calls, SB calls.

KsJd6h - I have two bd fds
pot - 12000 - I have approx. 2 SPR
SB checks, I pot, BTN calls, SB shoves, I call the rest, BTN says that he needs a miracle and calls it off.

Standard shove for me right?
SB shows 9TJQ rainbow and BTN shows ATJ7 with four diamonds.
After the hand SB was kinda tilting and disscussing with me, whether he had to go all in on the flop, I was like that I probably would have folded since he has dominated draws + I usually has high cards and AA heavy range so I block a lot of his outs. What do you think? should the SB player go all in there? Also there is the big stack that he needs to worry about.
