Calling down with TT is a bad play because you are not giving AK a chance to fold. If he spikes an A or K on the river like this hand, you will lose. I think you must get a raise in on the flop or turn. Personally, I would raise the flop and call a 3-bet. If Villian calls my raise on the flop, I will bet when checked to on the turn. If Villian 3-bets my raise on the flop, I will raise his bet again on the turn and fold to a 3-bet. If he just calls my raise, I will check behind on the river.
