Match Play. Red leads 4-3 to 7. How should Red play 21?

For money this would be a close call between the pure 8/7*/5 and the safety-first play of 21/20, 8/6. 10/7* is too loose irrespective of type of game.

When your opponent is four points away from winning the match a gammon with the cube on 2 works with perfect efficiency for him. Therefore, you should not create positions that risk that scenario occurring. To that end 8/7*/5 is a bad error and the only sensible move is 21/20, 8/6 preserving the slender racing lead and leaving nothing for White to attack. 10/7* would be a blunder at this score.
