I don't like this bluff for the donk range of BB is not always so wide.According to the line of this ways-pot both of 3 players can finish the flush on river,So it's always meanless to donk with str8s for thin value,so u r trying to convicing him to laydown lots of flush.What's more,U still have to worry about Btn's action,and the nuts hand is 9djd,Ur block card isn't so perfect.Unless U have other reads on the villian here or it will always be -ev action here.

Still, U r really tough player,

You don't need to risk this much to fold out a straight. This size would be targeting flushes, and that can get iffy. Given his size, weighted towards straights, I think going $100 makes you more money.

Depends on how strong villain is. You actually rep your exact hand much more than you rep a flush. Vs low wtsd regs this should be fine regardless.

you don(t have a lot of flushes by not betting turn this could be a problem sir
