Don't really thins your line makes sense w/ the 3bet, cbet, check, then check/raise. Probably not a profitable shove. But he had nothing so you benefited...a lot of the time I'm not shocked when he calls with JJ or a 9

I know that a 9 will pay me, but maybe I could represent aces or kings, or a set.

pay you? we have A high.

fold river > triple > this line
