could (should) i have got away from this?

[randommuppet]

yesterdays party $350k , just before 3rd break, im in bb with K5, i have T13000~, around 220 left from 1500, top 80 paid

open raised to T600 from mp (blinds 100-200) folded to my BB - my table image is TAG, not played many hands have about double ave stack for tourney and am third in chips at my table - ive been calling reasonable sized bets on my BB with semi-sensible hands and have managed to get a few favourable flops to defend with so far

flop comes K95, two spades (ive none) 1500 in pot - i bet out 1000 other player thinks then pushes (hes one of the two with more chips than me) - i call and he shows K9

im thinking with my stack size i could have afforded to fold here - however a win would push me to ~T27000 and put me in a very comfortable postion

i figured him for A something but i guess with the trips possibilities (55 or 99 would fit his pre flop raise i guess but not AA)it should have been easyish to get away from - in my defence the table seems to be pushing with most pairs pre flop (decent mix of reasonable and shortish stacks so quite a few show downs) - MP player has been slightly more aggressive than average i would say

any thoughts greatly appreciatted (although i suspect ive answered my own question) - essentially who would have folded here and how often?
