I would fold. I don't trust them to fold after putting 475 of their stack in, it's too large a %. If the BB had many fewer chips, reraising would be more attractive, as the button is more likely to fold and try to sneak into 3rd (although this doesn't mean I'd recommend it).

Close between raise allin and fold. I think you need to go with your read on the player. You want a decent chance of him folding if you allin, which seems unlikely.

Just about an hour ago. I was SB with AJ hearts with 5k chips. Shortie went all in for 800, I called, 2nd shortie called with 600 left. i missed flop, and turn. She pushed on turn. I folded. river was A. she had Q4 he had Q 10. she went out in 4th. This has nothing to do with your situation, but it just shows what people will do if they are greedy for chips.

Let them fight it out, push them around a little but try not to get too involved or you might spill some chips their way.

Pretty darn close if you ask me. You might have more FE than in normal situations + you might just have the best hand.

Like ChrisV said, I'd have to go with whatever read I had. Up that kicker a few pips, or give me a pocket pair, and I'm pushing though.
