re: Poker & Is an overcard on the turn a good spot to double barrel in microstakes?
Micro stakes are a very value-oriented game with not much bluffing
going on. The reason for that is there are so many loose passive calling station fish.
In certain spots, on a dry board, if you are the original opener and villain shows weakness, a delayed bluff on a A or K works because villain will put the A or K in your PRF raising range. Other times, it may not work at all.
Like you and other people said, it is situational and villain dependent. So many variables are in play that sometimes overcards are a good spot to bluff; other times they are not.
