B&M - 1st Hand Push - What are your ranges here?

[Poker Jon]

Hi All,

£30 Freezeout tourney ($50) 100 runners, top 9 paid.
T2000 and blinds 25/50 first level going up every half hour. Relatively quick structure, where you need to get chips quickly in the middle stages of the tourney.

I am in BB.

UTG folds, UTG+1 raised to 150, MP1 calls, MP2 fold, MP3 raises All In.

My questions are:

What are your calling ranges in the Big Blind on the first hand?
What ranges do you put MP3 on for his push on the first hand?

Will give results later.

Cheers,

Jon
