Spiffy

Hi guys,

Thinking about this spot, I'm 99% sure he doesn't have QQ/78s in his flatting range, so his range must be capped at AQ being the best hand, giving me the possibility to overbet my strong value hands alongside with the right proportion of bluffs (basically Axs I whiffed with) to put huge amount of pressure on him. Then a question popped into my mind:

Is also a viable strategy to take the same range of hands, and x/r (or x/jamming) the river instead?
How would you compare those 2 strat?
