I don't really feel I'm in a position to be giving advice but here's my opinion for what it's worth.
I think I'd be prepared to check this one right down to the river with a view to calling any bet he may make on the turn or river providing a K or running straight cards don't come. Make the first move and you only get a call if you're beat (and I think any A would call in this spot) whereas checking and calling any future bets gives you the chance of doubling up against a lower PP or outright bluff. You're leaving yourself open to being outdrawn but I think that's a chance I'd be prepared to take.
Like others though, I'm pretty sure I'd be pushing pre-flop.
