Positioning after a stroke

I noticed that I'm consistant if I stand in one position. I do chopping, and I can do consistant chopping if my opponent returns to the same backhand position all the time. The problem is if the opponent hits the ball (or pushes) to my forehand. I move from my backhand position to forehand, and makes a mistake sometimes, because I've to reach further to hit it.

The question is, after every stroke, do you have to position in the middle of the table or move in the opposite direction (to 'side' and to 'in') to take the next stroke, to be consistant.

What tips you guys can give me to be consistant in the game if the opponent pushes or do a lot of underspin. A coach advised me that I'm consistant when I'm at a study position, but not consistant when I start moving, or the opponent speeds up the game.

Footwork, work on it.

the shot you make will decide the position you should take to recieve the next shot i.e. lets say both players are RH and if you make a shot wide to his FH corner you should move towards your FH corner as he has to hit across the table.

    If you hit the ball to his BH but not really wide then stand perhaps slightly to the left of the center line so that you can cover any down the line shot with your FH and also cover croscourt BH shots,in other words go in the opposite direction to where you have hit the ball 

If you get into the right location and position quicker (footwork), then you will have time to get steady to make a better shot.

Anticipate where you have to go, go there quickly, then get your shot ready.

I use Long Pips (Flint III) on the BH. I love it.
