I dont think you have to worry about that here.

If he calls you down once with A high he will remember that semibluff for ever and you should adjust by not semibluffing.

If he folds you should just semibluff and take shots in general untill you see him call you down and then change back to not taking shots/semibluffing

From a game theoretic POW balancing is only something that is optimal when villain takes a strategy that makes you indifferent between takings a shot and not. Since most TAGs will either call down or fold indiscriminately with A high, you should just choose the strategy that is best against that strategy. (I hope I make sense)
