Fold. Effective stacks are too shallow. It's early in the tournament. I would consider a 4 bet shove if BB had been overly loose pre-flop.
Generally you need about 8:1 implied odds
to set mine
Starting with 6000 effective
1700 in the pot (hero 400 + sb 100 + bb 1200)
800 to call
4800 effective stack remaining on the flop
Assuming hero doubles up with a set+ and loses nothing more otherwise, it is 800 to win 1700 + 4800 or 8.125:1 in the best case
Then there are the times hero hits and doesn't get paid or loses with a set.
Quick estimate for set mining is the 20/5-10 rule
hero needs to be able to win 20 times the bet to set mine (about 80bb effective here)
here should generally not risk more then 5% of stack to set mine (maybe up to 10% in special circumstances)
800 to call times 20 hero needs 16k to call
