I think your line is OK on other streets. Amounts are good too: appropriately aggressive. Like I said, its tough to put short-stack on anything, and bigger stack is most likely drawing (was drawing) or TPTK (not likely he has two pair with no raise on either flop or turn). However, he'll lay down those hands on the river, and hence he only raises with hands that beat you. Thats why betting the river is not a good idea. I think you take down this pot (at least from the larger stacked guy).
