villain unknown. when he raises flop his range is fds, kq+, kk/aa, tt-jj as random bluffs and 77/22. i have 63% equity against that range, and 42% when he calls me shove assuming the fds call.

nl25 is passive, but folding seemed too weak, calling makes a mess oop (maybe call and lead turn?), and i got told to 3bet flop oop in another tptk hand like this.

could someone summarise some basic lines for these spots for me?
