History

I have established a fairly aggro dynamic with a reg in my live 5/10nlhe game recently and encountered a spot last night where I'm not sure what was best. I am a pro reg in this game and villain is a pro who travels from abroad to play for a few weeks every couple of months. On this trip we have had a more aggro 3b/4b dynamic than previous after I got to sd with a couple of light 3b early in his trip although gen I have a 3b % that is on the tighter side of taggy in these games. He has a quite laggy pfr generally but tightens up postflop. He has been running bad/losing on this trip although he was winning on the night. I know he respects my game but possibly thinks that atm I am being more aggro/creative in these spots than I actually am. I feel like his adjustment to our recent dynamic is to 4b wider for value than previously and to be a lot stickier vs me in gen especially in 3b+ pots.

Hand

Weak tag limp mp(2k), Villain iso mp to 60(4.5), fish flat hj(1), reg flat co(3), I sq otb with AKdd to 275(5.5), mp fold, Villain thinks and 4b to 700, folded back to me...

My reads are that his 6x pf is quite strong (99+, KQs+) especially as there was a whale in the bb. What do you like and why?
