illogical blind move in...thoughts?

10/20 live, most of the live players have left and it's now 6 handed with me and several tight players. We have been trading blinds around for about half an hour, avg stack is 2.5k, I have about 4k and have been blind raising preflop 50 - 70 on the button and in the CO every orbit to try and develop some action. Hasn't been working out too well. I blind raise 50 on the button, folded around, I don't look at my cards and the BB who hasn't looked at his cards blind reraises to 100. He is very tight preflop and by the book, hosts the game, and has a very sound understanding of the "math". Occasionally he will do some wacky things, but generally he has very good hands when the money goes in, he knows how to have a good time gambling though. Anyway, he blind raises and I now look at my cards, 97o, ok. I call. Flop comes 883r He moves all in for 2.5k.

What range of hands do you call this with if he hasn't looked at his cards?

What range of hands do you call this with if he has?
