250 person tourny down to heads up, you and one guy. You have 100k he has 150k in chips. Blinds are 5/10k.
You are delt

and are first to act. You raise to 3x the big blind (this is key moment #1, so feel free to dissagree and correct me).
He calls. 60k now in the pot, you have 70k he has 120k. Flop comes down

. You are first to act. What do you do (this is key moment #2)?
If you decided to check, or bet (but didn't go all in), he now puts you all in. (this is key moment #3). Do you call or fold?
Very curious to hear your responces on how you all would have played this, thanks.
