So this is my first post and I know I should be using the hand converter but I did not save it. this was a $24+2 32k guarantee mtt.

I had JJ in the Big blind with about 14k in chips and blinds were 150/300.  Player in the UTG+2 position was moved to the table two hands prior to this hand so I was not sure what his style was, but he had 10k in chips.

So The player in UTG+2 opened for 600 and it folded to me so I chose to just flat.  Flop came AJ5 rainbow.  The pot is 1575 so I bet 989 and he calls.  Next card is Q, so now I am obviously worried about the K10, but I choose to bet 2299 and he calls again.  So now the pot is 8151 and a 2 hits the river. There is no flush possibility, but I am worried about the straight so I check hoping he checks behind and he shoves.  I call and he turns over K10 so I am frustrated and I was just hoping someone could give me advice on how I could have played this better?  I know this may be tough to read so I apologize in advance, I will use the hand converter next time.  Thanks.
