[AKQJ10]

Oops, I forgot to notice the preflop action (and my post timed out before I could edit it.... stupid computer problems, grrr). The raise on the button is good, but should be more than 2x the blind. For all practical purposes a beginner is likely to encounter, YOU MAY EITHER FOLD, LIMP, OR RAISE A MINIMUM OF 3x THE BIG BLIND (preferably with emphasis on the first and third options). YOU SHOULD NOT RAISE THE MINIMUM ALLOWABLE, even though most sites make this the default. You seem to have problems with minraising, and you need to break that habit immediately.

At any rate, once it's reraised behind you you can safely release ATo unless the reraiser is a known maniac. Every reasonable reraising hand (AA, KK, QQ, AK) and several questionable ones (JJ, TT, AQ, AJ) dominate AT. Unless you have a read on the raiser, figure you have three or fewer outs and throw your hand away preflop.
