BB Small stack facing miniraise

[pasita]

Hi all,
my first post to the forum. I hope this topic hasn't been covered already, couldn't really find anything (at least recent) on this.

I've made a play in two MTTs ($100) that isn't by the books, I think... I'd like to hear some comments.

Basic situation in both: I'm on BB, my stack about 10BB (average between 15 to 20), antes are in so pot is about 2BB and a midposition (slighty larger stack than mine) minraises (2 to 2.5BB). All fold to me, I'm holding
A) KQs
B) QTs

No specific reads on the raiser, tourney A is just in the money, B is getting close... the big money is still far away.

Other notions:
I've been agressive lately (case A I've just come down from chiplead to below average, case B I've come from 2 BB to life after pushing any paint for two orbits).

Several Ax- stealers have lately called a push, seems that the table is full of players desperate to double up.

All of that combined, I felt I had no folding equity by pushing all in. Also, I'd rather not die with just K or Q high just yet.

So I reasoned I'll take the huge odds for flopping a pair and die with that if necessary (antes are in, with a standard contbet from villain I believe I'm getting a minimum of 6 to 1 for flopping a good pair and then checkraising all-in). I understand the risk of being dominated but with those odds I took it and went fishing.

So I guess the questions are... do my odds calculations make any sense? Is this strictly all-in or fold preflop?
