i think its a big mistake to assume he's shoving wide. even if this is the second time. he has no reason to be shoving wide here IMO theres much better places to be staking off.
i ran the hand in SNGWiz it says JJ+ if hes shoving "loose" which is a5s+, A9o+, all pairs, KQ, KJs+.
I'd call with AK but I'd really hesitate to call a shove htis big with TT when we are in a very good position to continue stealing.
