I played the $10 deepstack 1.5K guarantee on Merge this afternoon with 20 minute blind levels.  At this point in the tournament there were 53 people left, 27 cashed.  Blinds were 250/500 with an ante.  I have 13K in chips, avg is 18k. A player in early position limped then the villan directly on my right opened to 2k from middle position.  I was in the HJ with AQ.  I have been at this table for about 20 mins and had 3 bet this guy from late position during the previous orbit when I had him covered, he folded.  He has since doubled and has me covered with about 30K.  Is the 3bet shove here obvious or is there an argument to be made for folding?

Thanks
