I have about 620 behind and am in for 300 in a wild 5/5 game where people will call 200+ preflop. fishy player completes straddle in the BB for 20 with about 1500 I call 20 with AKo UTG, shortstack UTG+1, somewhat tight player shoves AI for 150, loose button with 3k flats, BB fish flats.
I'm worried that if I shove the 600 one of the players may call 3 ways and I don't have great equity underrolled. Should i have opened strongly to 50-75?
I hate putting in 150 and then having to fold out of position and with ace high it's difficult on some Jx, Qx, flops to know if I have the best hand and my stack is for this game considered short
