good read my friend!!!!!That's a weird donk jam on the turn, if he's going to put all the money in the king can't really change anything that would make him all of a sudden jam. I feel like the best play is probably to fold, but I honestly just don't understand why he'd jam there and I would probably call. You having the q spades is kinda bad because you block quite a few of his most reasonable flush draws and especially combo draws. I kinda wonder if he has kx of spades, it's one of very few combos that make any sense to me even though making that play with kx spades is still bad.

Standard isolation spot, I like the 4BB sizing.
Turn
As others have said, this is a pretty weird donk jam. If he had an ace, he would probably have check-jammed the flop, and even if he just made two pair with a weird K6 or K4, why not check to you again and give you the chance to hang yourself. There is so little behind, that even if you check back, he can still get it in on the river. So I think, this looks bluffy, and for that reason I would make the call.
Results
So he got there with his silly draw, and thats just poker. Nice hand and well played
