Rewarding bigger hitting isn't in the spirit of the game, either: I'm pretty sure even Barry Richards (who found the ropes more often than most) would agree that the art of batting is surely about rewarding selective, intelligent strokeplay based on judgement of the risk involved in playing a particular shot to a particular delivery and on accurate placement into areas of the field where the ball isn't going to be intercepted by fielders.

To my mind the "six" should be a rarity in any form of cricket... not because I'm averse to lofted strokes (lifting the right ball over the field strikes me as fine).. but because the bowling in international cricket should not present batsmen with more than the rarest opportunities for low-risk opening of the shoulders.

Bowlers only have a chance in cricket if trying to hit through the line to any half-decent delivery is a low-percentage option to be passed up in all but the most extreme situations.
