Of course I don't do this against someone who aggressively defends their BB. If they raise me, I'm tightening up to like my CO range. If they're calling me a lot, I'm fine with that because they are folding a lot of flops, or getting their money in bad postflop since I'd rather be me out of position than them in position. Note that the raggedy-looking K and A hands I'm raising are ahead of BB's random holdings. If I'm really having a lot of trouble, I'm going to have to start completing with my nice postflop (suited, connectors, etc.) hands and tightening my raising range. If they start raising my completes, I'll have to start completing a few big hands. etc. etc. So yeah, this range is in no way static.
