Sometimes, fourth suit forcing works equally well. For examble:

The standard auction would begin:

Unsure of the best contract, responder could make an artificinl fourth suit bid of 3 diamond. This is a marathon bid, forcing to game. The auction would continue:

Over the artificial game-forcing 3 diamond  bid, opener can rebid the five-card heart suit, and responder can place the partnership in the best contract. In 2/1 Game Force, responder would have made the descriptive rebid of 2NT, but both approaches would lead to the same result.
