As everyone knows, one type of backhand is vastly superior to the other. It is well known that it has the superior power and control, and it is clearly better from all parts of the court in both attacking and defensive situations. Naturally, which one of the shots has these magical properties depends on who you are talking to. Obviously we will never agree on which is the 'better shot', I thought it might be interesting to discuss the source of the differences, so we can try to understand why players might find it much easier or harder hitting a particular shot. My theory is that the differences between the two shots come from two main factors. The first is the fixed wrist/forearm position on a 2HBH, which make it much harder to vary the amount of topspin or trajectory with a similar swing path. This means that 2HBH players have much less ability to vary spin and direction on the fly, but it also leaves less room for unwanted variation. The other factor is the reduced shoulder mobility on a 2HBH, which limits variation in arm movement. I think that this is the reason that the 1HBH is seen as having better reach, as the limited shoulder movement becomes a problem on the run for the 2HBH. However this same limitation maintains a stricter racquet face angle on shoulder height shots. These factors result in much less ability to vary a 2HBH. In certain situations this is a benefit, in other situations it is a liability. The diagram shows the possible wrist and shoulder positions just after contact for a 1HBH and a 2HBH Situation 1 - The player steps in to win the point with a flat shot and gets an unexpectedly low ball beneath net height. 1HBH: The ability to add extra topspin, at will, allows an aggressive shot to be played. 2HBH: The ball is too low to hit a high speed flat shot, and extra spin cannot be added, so the player is forced to hit a neutral or defensive shot. Situation 2 - The opponent hits a big inside out forehand, whilst the player is on top of the baseline. 1HBH: The ball is coming through the court too fast, with too much spin, so it is too hard to time elaborate wrist movements, so the shot must be pushed back, giving the opponent an easy follow up shot. 2HBH: The simplicity of the shot removes some of the difficulty timing the shot, so a abbreviated swing is possible, placing the player in a less defensive position for the follow up shot. Situation 3 - A shoulder height shot in the middle of the baseline 1HBH - An aggressive shot can be played, however the high contact point will diminish control. 2HBH - A high 2HBH can be hit very forcefully cross court or down the line with good control. Situation 4 - A net height ball outside the tram line. 1HBH - The good potential for combined spin and power out wide allows for a sharp angled, Gasquet style, cross court or down the line winner. 2HBH - The 'shorter reach' makes it much harder to reliably hit an aggressive shot from this position. Obviously good players will find ways to work around these issues, and the grip used also plays a major part in determining how easy certain shots are. But averaging over all players, what are your opinions on this idea, and can you think of other factors which might come into play. DISCLOSURE: I am primarily a baseliner who hits 2HBH, except when hitting ridiculously wide defensive blocks. In general I feel that the 1HBH is superior on attack & the 2HBH is superior in neutral situations.
