I don't think you 3-bet this to play TPMK for value thru 3 streets... I'm with you thru the flop c-bet, but I'm prolly check/folding this on the Turn. You're behind AT+, A2, A3 & A7. That puts you ahead of only 4 Ax combos and tieing with 1. You're also behind 22,33 and any 7 on the River. The only way you win this is a) you're up against a total f-tard betting 3 streets with sub-As hand or b) someone decent bluffing you triple-barrel style... I'm personally not waiting around to find out...
