Bluffing is when you can win only when the other player folds, otherwise it's Thin Value. People talk about correct bluffing frequency, I look for the right situations and don't particularly care about frequency. Knowing your opponent is capable of folding is the most important aspect. Bluffing a lot = -ev, what is "a lot"? IDK I rarely
bluff and do it when the correct situation unfolds and I
think I have a good read on my opponents hand strength.
In Omaha I have the A club and a busted straight when the third club card comes on the river, I'll bet the pot when I know my villain is capable of folding, if he's a stupid loose player he'll call every time = -ev.
