To simplify my thoughts:

I think Sauce puts you on a very strong range here, and is also expecting you to be aware of this.

Due to this I think he bets small because he doesnt expect you to call a big bet light + doesnt want to allow some hero folds...... and is also forcing you to cr a wider range of value hands due to his sizing and potentially bluff if you ever get to this spot with air as you can credibly rep flushes +.

He is expecting to make more from your weak/ mid strength hands, more from your super strong hands that he's coolered, and allows you to bluff with your air if you have any.

I think the reasons which Kanu bet 1600 on the K 9 4 5 K board is not solely to induce from the weaker parts of your range.

I think when you get to the river like this most your range is strong, very strong actually.

There shouldn't actually be much stuff you need to bluff with in your range, if any at all (I think he expects your lead- call, check call range to be strong). I would think that the reason he has bet this size is because he is giving you credit for recognising how strong your range is by this river... and actually expects you to make some fairly big hero folds with Kx if he goes for a large bet. I do not think he expects you to be comfortable check calling a v weak king to a large bet when you know that your range appears to be K x Plus on this river...

If he gives you a range of kings/flushes/nines/some small % of air, he has must have bet small in order to;

a) ensure that you shove flushes- I am not sure how often this is true- sounds like it is less true than he thinks actually, but I would expect you to cr most flushes to 1600 bet?

b) not allow you to hero fold weak kings- which I think you should if he bets big on this river.

c) at least allow you to make a bluff check shove if you have got to the river with an ace high/ jt type hand

d) simply extract value from 9x, which isn't calling large bets on this river
