If I miss on the river, are there any on which I should bluff (if the SB checks)?

you've said nothing of your opponents, so I would venture to say 'no.'

No.

Do you think your bluff will work more than 28% of the time? Because I'm leaning towards "No."

no. heads up, maybe possibly probably no. here. def no.

Well I made the flush on the river (5c), BB checked, I bet and they both folded.

Without reads, I don't like the idea of bluffing into two unknowns.

Am I the only person who bets the flop?
