Eff. stacks on river is 842

How would you play this hand?

On the river when facing a polarised range like this i would want to c/r with my nuts and my bluffs that doesn't block his missed draws (or blocks his value), but the stacksizes doesn't allow this. I estimate his calling range on the river to be like 9Tss,KJ,JJ,77,KQ,KTs (23combos) and his folding range the missed spade-draws and a couple missed heart-draws(about 16 combos).

When im facing a range this polarised could I exploitative bet a really small sizing since his calling range will be about the same as if I bet bigger? He picks up som pairs on the Jh turn although that make him less polarised on the river and could find a call vs smaller sizes and fold vs bigger.

Thanks in advance RIO
