I feel that one of the biggest leaks in my game is how i play the big blind facing a raise. Usually i play pretty tight knowing I'll be OOP on the flop. When I do find a decent hand to defend with (K9+ when the flop will be HU?) I feel like I'm forced to play pretty passive post flop and do a lot of guessing. I know that I should play tighter against early position raisers than later position raisers, and I know that I should change my range depending on who is raising, but I don't think I really know what the standard is. Can everyone tell me their typical hands that they defend a mid/late position raise with, and how they usually play it postflop? My thought process preflop is usually, "If I play this hand, what can the flop look like for me to like my hand?". Aside from defending the big blind, when it's folded to the small blind and the small blind just calls, I usually raise 4x with any two cards unless they're a nit/call station/or I have reads that they limp with monsters whenever they get them.
