Steven,
I’m curious why you think 3x is the “correct size”? If I have AA and open to 5x or 6x and get called in 3 spots isn’t that good? At 1/2 if I see someone open to 3x, I laugh to myself and know they’re a fish. 3x isn’t going to thin the field at all. Anyone limping for 2 will call 6. So you don’t get protection for your big hands or much value from worse hands.
