This is probably not a good idea! The Professor winds up passing his 3 aces to Marvin. In doing so, he may have given Marvin the tools to shoot the moon. This can happen if Marvin has a couple of high Hearts cards or maybe no Hearts cards at all, but a few other high cards.
If I had this hand, I would probably hold onto all of the Hearts cards. I have plenty of low Hearts to avoid taking a trick filled with Hearts, and I could try to dole them out onto anyone I chose by creating a void in another suit as quickly as possible.
Instead, I'd probably pass the Ace of Diamonds to try to create a void in diamonds. The Ace of Clubs is probably safe to keep - I'd likely be able to play it on the first trick. Instead I'd get rid of middle cards like the Jack and 6 of clubs.
Another option would be to hold onto all the Aces and attempt to shoot the moon. But with all those low Hearts and Spades cards, it's pretty risky.
Now, the second trick is being played. The Professor has no Diamonds, so he is planning to break Hearts by playing the 10 of Hearts card on the trick. He knows for sure it will be taken by Sandy. It looks as if his strategy is to systematically get rid of his point cards as soon as possible.
Given that he has earlier given his Aces to Marvin, this is probably a good idea. It's very likely that Marvin will take some point cards with one of those Aces.
However, in general, you probably don't want to get rid of all your high Hearts cards until you are sure that no one can shoot the moon. For example, if you were holding the Ace of Hearts, you might not want to get rid of it, yet. Instead, you could play your next highest card, and hold onto the Ace just in case you needed to use it to prevent an attempt to shoot at the moon. If you had to do this, you'd be playing the role of "sheriff". This and other Hearts strategies are explained on Mark Whitley's great Hearts Tips pages.
