Do i put my chip leader stack at risk?

[bsiu5]

the only reason why i raised was because i built up an image at the table for raising only premium hand. i was willing to lose a small piece of my stack if the flop wasn't to my liking, so they can't get a read on me. i had the flexibility because i had such an advantage with my chip stack. i figured by doing so the blinds would have folded and it would have been to the EP, which in turn if i caught anything i would have put him all in. my chip stack compared to EP was (EP 2500) me(30000). when i do get a good hand say AA i want people in the hand hoping to catch something. People, didn't want to play with me because my stack was so big. my goal at that point in the tournament wasn't necessarily to take more chips but to add deception for future hands in the tournament, and to take players out of the tournament.
