This is prolly a standard spot, but just never really had to deal w/ this too much in the past
V1 (CO): Old man, limp happy, fairly passive
V2 (Button): 30ish man, plays LAG and seems to be one of the best players at the table
V3 (EP): loose fish
EP, ~$1,000
CO, ~$1,000
Button, ~$3,500
Hero, ~$2,000
Hero is dealt A

K

in the BB
EP limps, CO raises to $100, button calls $100, hero?
i know it sounds super nitty but i just folded, V2 was the only player at the table i was avoiding since he is one of the few good LAG players ive encountered, and didnt want to get myself into a big pot post flop OOP vs him. Also I felt like I didnt realy have much fold equity to the old man opening to 10bb.
Just wondering what is other ppl's standard line in this spot? What yout range for calling and range for 3betting?
