A forcing move is a move to which opponent has to answer locally to defend against an immediate threat. This situation occurs if one threatens to cut a connection between major groups or key stones of opponent's.
Sometimes it's hard to tell if a move is forcing. Example of this is joseki.
Example
In this position blue player has 2 forcing moves to make - c4 and c3. In case of playing c3, red has to defend with c4. In case of playing c4, red has to defend with c3. Otherwise red loses the game.
Notice that moves on a4, a5, f2 and f3 are not forcing. Against a4, a5 red has a choice of playing b5 which improves his position. Similarly, against f2, f3 red should play d2.
The point
There is a use for making a forcing move. In certain conditions a player can benefit from it and even a tiny gain may influence who wins the game. Look at the following example:
The only winning move for blue is the forcing move on d6. If blue misses it the game proceeds as follows and the winner is red.
If d6 is played then blue win.
