Pair Aces Busts to Rivered Flush Draw, Out in 5th

With already a very poor internet connection to work with, I settle down and work on my 6th $11+1 Sng Turbo of the night. With finishing 1st in the first two games and 2nd in the third, I jump out of the gate with a hot start, inching closer and closer to my goal. I get up halfway through the tourny with my pocket queens holding up against AT, making an ace high straight on the river to put myself 2nd in chips. After two previous brutal losses, a non-cash in this game would put me at a 3-game losing streak. With only 5 players left, I get knocked out, losing to a rivered flush draw. Take a look:

Kris Homerding finishes in 5th place

Now here's the situation: When I push my remaining 1,290 chips, the pot size is at 1,680, in which 680 of those chips are pom_1962. With 3,605 chips remaining in his stack and 680 already in the pot, he calls my 1,290 all in bet on a DRAW; 35.8% of his stack. At no point in the hand was he "pot committed"; just another instance where I lose to a bad poker player.
