i like it and agree with your reasoning :)
i could also imagen leading turn but xr seems good to me as well

nice hand

i would not worry about finding enough bluffs to balance your turn x/r. usally bluffs follow value not the way arround. bluff with str8 draw - easy

i think on the river you have a very strong bluffcatcher in sense of relative handstrength because you block KK QQ and his line is kinda thin w/ 22. so i think KQ is a stronger bluffcatcher as 22. that being said i still could imagen folding exploitivly with some small reads or because of population tendencies. most ppl on 1/2 are huge nits especially on river and especially deep.

what is the purpose of your turnbet? i dont like it especially in combination with your sizing. if you frequently bluff with showdownvalue hands like this it is perfectly fine for BU to fold like ~70% because he has an easy fold with hands that doesnt beat your bluffs.

if you bet those hand from time to time in mixed sizing strategy in a perceived polarized 100%ps / >ps bet range to make his draws and weak SD value hands indifferent it should be fine but i think thats a little overdone and wasnt your purpose. xD

tbh i would just check turn.
