Middle Set

[esaresa]

$35 buy-in, 3 table (plus alternates) NLHE tournament at a local casino. Full table and I'm down to 1500 of a starting 3000 stack (I had already donked off half my stack - but that's another story). Blinds $50-$100 and I make it $400 to go from UTG w/ Pocket 8's. Cutoff flat calls and the blinds fold. Flop comes 8-K-3 unsuited. I shoved. Was I too impatient, and incorrect in feeling there wasn't much point in making a continuation bet and leaving myself $900 in chips if I got re-reaised all in? Thanks
