When this attacks a hero, intimidate them.

If the defending hero has no cards in hand, this gets +3

From the Heavy Hitters release notes

This does not trigger if you attack anything other than a hero (i.e. an ally).
Unlike some other intimidate effects, you must intimidate the hero being attacked. You cannot choose to intimidate any other hero.
If the player has cards in their hand when this attacks them, then they have no cards in their hand (e.g. being intimidated and/or defending with cards), this will still gain +3. If the player has no cards in their hand, then they draw or otherwise get a card in their hand this will lose the +3.
These abilities are not functional when this card is not attacking on the combat chain. E.g. It doesn’t have +3 when defending, discarded, banished (from hand), or revealed for a clash.
