AA hand - I don't raise that particular hand from anywhere and I fold it to most signifcant raises.

JT98 hand - I raise from LP and MP, call from EP. I can't see any way I'm folding this preflop in any situation but I'm not too bothered about getting tons of chips in. Good enough to raise late on, though.

KKQQds - I raise from EP to build pot with this one, just one of my little foibles (sometimes I might just call, frankly I think it makes not a bit of difference, you're still seeing a fop regardless). I definitely raise it (if unraised) in MP and LP, and if it comes to me unraised I might add a couple of BBs from the blinds to swell the pot a little and allow a bigger reach on the flop if I hit, though not always. Again, I think it's a taste thing and EV-wise not a major decision, though I have no empirical evidence to back that feeling up. I am not folding this hand preflop in any circumstances and will go to the felt with it if necessary.
