hey guys i'm having a debate with a friend on why gto cbet 1/3 on flop like A72r on hu sgr pot
so for me its because we have a lot of air and want vilain to fold with a cheap bet, but he disagree saying the bigger the bet is, the more bluff we have, so if we have a lot of bluffs we should bet more, like 2/3

the 2 statements seems true, so i dont really know what to say, any idea? cheers
