Kitty and gunshot were both tight players...Comments on what you think I did wrong...im so pizzed

of course bet less on the turn. tight players have tight calling ranges so what that means is....you aren't getting called by a 7-hi flush here usually. you will only get called by a better hand. there's no reason to bet that much. if they are behind then you made it very easy for them to fold. if they are ahead then you made it very easy for them to stack you. congrats.

A. Convert your hand histores
B. Minraising is stupid, esp. on a flop like this. Call that bet since a pot is being built for you and there's no need to build it further. You don't have the nut flush draw.
C. Why would you push the turn? You lose a TON of value from non-flush hands, and shit like this happens.
D. Minraising is stupid.
