People usually have a 3b or fold strategy from SB, unless BB is fishy and you want to have him in the pot.

Well I agree with Mancuso, most of the time you would like to 3bet or fold in SB so dont put too much weak hands like low Axs hands in you 3bet range.
Post flop that's a tricky line you have taken here, very exploitative. Most of the time I dont have that kind of hand in SB neither a donk strategy OTF, so I dont know but I dont like so much betting so huge on river, you didnt bet the turn because you didnt want to be face up but you made a huge overbet OTR? To me thats much more faced up than second barrel the turn but it worked :p

As played, turn is a way way more bigger bet. This helps you setting better stacks for a river shove which is what you want. I would consider to pot OTT or just go to 1.5 PSB, probablt the latter is better.
Also at these stakes people don't havethe fold button, so you can capitalize on that

You generally don't want to call with these hands from the SB, although it's probably fine if there are weaker players involved (raiser or the big blind).

Flop I tend to just check everytime on every board, makes life easy and it's good 99% of the time, whereas leading is often inferior as an option.

Turn I would raise, you want to get all the money in by the river.

River shove is pretty cool as played because most players have a hard time folding a straight at NL2 I would imagine. But I don't think we have to arrive to a situation where we're forced to shove this much money into a small pot, I think we're better off raising the turn and then shoving the river for way less.
