Is this a fold?

[Pat Southern]

We're in the money in the 500k guaranteed, about 300 left when this hand came up. I've gone allin in 3 of the past 5 hands and not been called. This guy had played very tight the entire time he was at my table (like 30 hands), but when he played a hand he opened with a raise.

Now at the time I thought sweet I finally have a hand and somebody is pushing into me. In retrospect, after putting him on a range of hands I'm not so sure. I think this is a fair range to put a tight/somewhat weak player to push with 9 BBs:

P.S. yes I'm posting this hand because I lost, but I'm starting to think I overvalued having a big hand and ignored hand ranges. Can anybody justify a fold?
