Weird 15/30 AK?

[BlindingLaser]

My two opponents in this hand I've had a fair number of hands with...one of them is pretty fishy and totally random, the other is tight, aggressive, and tricky. I put fishypie on any piece of the board, a lesser ace, any pocket pair...his range is very wide, and he could even have a draw of some sort. If I put TAG squarely on AK (and think I might be able to push him off it), is this okay, or am I just straight up hemorrhaging?
