You hold: ♠ A5 ♥ AKQ642 ♦ 8 ♣ A765

You could jump to three hearts, but in two-over-one that should show a self-supporting suit. You could also start with three clubs in case you have a fit there. This conveniently shows extra values, or at least five clubs. However, since you are in a game force, you should seek to emphasize the good suit and save space with a call of two hearts. There will be time to catch up later — you basically have a slam drive, after all.
