I am not strong at math and would like to know how to approach this sort of situation:

we find ourselves on turn with a value hand and want to (continue) betting until all-in. A9 in this case on 492 3 rainbow board.

We have 24,700 effective stacks and the pot is 12,948

Now the pot is quite dry, but we want to shove most rivers. It seems like a simple spot, and it is, but the process is not too clear to me.

How do we choose the best sizing? My uninformed process goes something like --

10,000 would leave 14700 into 13000 + 20000 = 33000 and 10k is a very large bet on this texture and likely to get more folds, so bet a bit smaller than 10k

thats about it! I would like to know if there is a sort of fine-tuning that can be done here.
