Lets say we play OOP in 100BBs game and decide to reraise low ds rundown such as 7654, opponent just calls and flop comes:

987 (19BBs) spade spade,  and our hand is 7spade 5spade 6diamond 4diamond

Do we lead here? ( I guess we do)

What if we c-bet 1/2pot and got reraised to 3/4pot, is it call/fold/GII now in such low SPR spot?

Don't like these spots and I am not sure could I avoid stacking off in "not so bad spot" at first glance?
