When it comes to card play at bridge, the human brain is hard-wired to cash aces and kings. I know, because I see lots of beginners in action — right now, I am teaching two beginners’ courses with a total of about 700 students. (Don’t worry about social distancing — it’s online.) When I present them with a hand like this
♠A65, ♥AK4, ♦KQJ10, ♣A42, along with instructions to establish the diamonds, I can see them all nodding with understanding, yet when it comes to the play, the fingers somehow have a mind of their own. They cannot resist the urge to grab every ace in sight.
That should give you a gentle hint about how to play this deal. You are in four spades on the lead of the ace of hearts.
