Well played. You can't fold AK here...ever...(ok, i lie, but almost never). If he has any hand other than AA/KK, you have to call.

Open-pushing for 15BB is a bit excessive. In fact, I'd much rather raise it 3BB hoping a blind sees it as a steal since you're on the button. Some ppl defend blinds w/ a HUGE range of hands, especially any Ax. I'd much rather hope to induce a blind into overplaying his hand while you're a big favorite than simply pushing. You're much more likely to get action from worse hands this way.

Again, well played.
