Shortstacked on the Bubble... two situations

[Deuce2High]

Both situations all 3 other stacks are at about 2500 +/- 300ish

1st Scenario..
100-200 Blind
I have 800 chips dealt TT on Button.
No small blind.
UTG raises to 600 and CO folds.
Hero??

2nd Scenario..
50-100 Blinds next hand move up to 100-200.
I am UTG+1 dealt K8o with 600 chips.
UTG folds.
Hero??


What I did I'll put in white so if you want to post your response before you see what I did...

I think both of these are clear pushes... U lose all FE if u wait on the 2nd, and the 1st is too good a hand to pass up w/ 4x BB

1st hand is an easy push.

2nd hand is 4-handed as well right (so you are the button)? If so, this is a clear push as well.
