20. You’re playing in a no-limit hold’em tournament and it has been folded to you in the small blind where you’re holding a pair of deuces. The blinds are 300/600, and after posting the blinds you have 4,000 and the big blind has 20,000, as shown here:
The big blind is a fairly loose player and you reason that if you push all-in, he’ll call with a wide range of hands; 22+, A2s+, K7s+, Q7s+, J7s+, A2o+, K7o+, Q7o+, J7o+ (38.5% of all hands). What is your total expectation if you decide to push all-in?
