Playing at Sheffield main 10k starting chips... 45 min levels blinds are now @ 200/400 ave stack 14k. I must have a tight table image (took me 3 hrs of folding carp and only showing strong hands) and I am holding 12k in chips when the following hand occurs.
I am in the BB blinds 200/400 and a serial limper/good post flop player (holding 15k) limps along with a tilting station everyone else folds to me in the BB i look down to find K 5 off and check.
Flop comes
Action to me where I put in a bet of 1k hoping to take the pot down there and then. serial limper/good post flop player flat calls and tilting station folds.
Turn

Now I have a pair of kings with an open ended straight draw and decide to check intending on a check raise if my opponent bets. I check he throws a 5k chip in the middle and says "two thousand" to which I announce "ALL-IN" and stick my 10k is in the middle. He calls immediately and shows

The river brings a red 5 which is no help and his 2 pair bust me out of the tournament.
My question here is was I just unlucky to run into this hand? What kind of range would you need to call a player check raising all - in on the turn bearing in mind previous information etc. If you had played for this long would you be pished at yourself for busting out in this instant, would you think better opportunities will come..
Basically what are YOUR thought here ?
Forward Thanks
