women plays closer to the table, or atleast Asian style is closer to the table.
closer would be higher speed, and the BH to BH is a controlled placement.
The strategy is to place the ball and eventual making the opponent make mistakes.
That is the central issue. The speed at which the ball comes back on those shots from close to the table, off the bounce, while the ball is still rising, the setup for BH is much quicker, the stroke is much shorter, it has speed even if it lacks the power.
The big looping rallies with the FH have more power but they usually happen at mid-distance (3-5 feet from the table [1-1.5 Meters]). If you have not gotten your opponent to back up to mid-distance, and you back up to mid-distance, you are ceding position on the table, the ability to create bigger angles (it is easier to create bigger angles from closer). And with that position a good player can use your power against you if you are at mid-distance and they stay close. Taking the ball on the rise, off a heavy power loop....the ball will come back fast and the player will be using your power in their shot.
The women players I have played also seem to be way faster than most of the men I have played so the ball comes back at a much quicker interval leaving you less time. With less time, BH is more efficient than FH. s
At least, that is what it seems is going on from my perspective.
