tactics against my opponents

At my training school i have 6 different opponents: 

1) One of them is serving only top spin from side to side(he is
staying in the middle of the table) and then he
smashed or make a top spin to my forehand(right side of the table) or
to my elbow...
2) Another opponent is serving with chopping from the left side of the
table to my bachhand and then he is also smashed or make a top spin to my
forehand(right side of the table) or to my elbow...
3) And another opponent is serving with chopping, top spin and mix
spin(top spin and side spin) often from the left side of the
table to my bachhand or from the right side of the table to my
forehand and also make a top spin or smash to my forehand(right side
of the table) or to my elbow...
4) Another opponent is the defender and he is serving with chopping
from side to side and then he make a top spin or chop or make a
candle(balloon)(when ball is flyeing high to the ceiling) from side to
side...
5) And another opponent is serving with chopping, top spin and mix
spin(top spin and side spin) and then he is chopping and sometimes
make a top spin or smash only to my forehand or right side of the
table of the table or to my elbow...
6) And another opponent is serving with chopping or no spin(but very
fast) from side to side and then he is chopping and sometimes
make a top spin or smash from side to side(often to the corners)...

Sometimes all of them make a shots to my forehand and backhand or to my backhand only... Or something like that...

Can you write me what i can do to win the match? Can you write
me some tactics against my opponents?

Hi Yuriy,

Hopefully they are not watching this...

The main problem seems to be that they are playing the ball to your forehand and middle which is causing you problems.

In situations like this we always need to go a step back and see if we can stop them from making this ball.  It seems that your return of serve is not effective enough to stop them from making a topspin or attacking ball in most instances.

Think about your placement of the return to start with.  If they are getting a lot of free points by makiing this attackign stroke start to take some risks and see if you can stop them from this stroke.  Think about you rplacement of the return.  Put it to a position on the table that will be difficult to make an attacking stroke. This could be wide on theor backhand corner, it could be close to the net or it may even be wide to their forehand corner.

For each of these oppoenent work out where they are comfortable making this attackign stroke and where they find it difficult.  You need to watch them play other opponents and see if you can learn something from them.
