Speed Tournament Final 3. Open push K7o?

[Crispy]

Hero is chip leader. Blinds 50k/100k
SB Gulgory 200k
BB Random guy 80k

Hero gets dealt K7o under the gun. Pot is currently 120k with SB 50k. I figure I have a decent shot at getting SB to fold and getting headsup with BB who is all in. I therefore open push K7o. Now knowing Gulgory would only call with PP 99- AA, AK,AQ, AJ is this a clear open push?

Money for Placement
1st- 2700
2nd- 1700
3rd- 1050

Given the structure, almost any two would be a push. For all purposes, BB's hand is random. What makes you think SB is so tight given the high blinds?

The reason I put him on being that tight is because the BB is all in. If I win the hand the SB would profit $700. I just thought that might have been running in his mind.
