Bet sizing question
Rookie question but if I’m opening to 15 in 1/3 NLHE and get multiple callers each time, is the answer go start increasing until I see more folds? I started doing it and opening to 25 but got some angry looks from people in the casino just trying to see flops since I’m not ever limping.
Relatedly, why do some people open to 12 or 18 or 22, why not even numbers like 10, 15, 20?
