L1+X = one two pass. Players of pes1 will be familiar to this neat trick. Its a one two as
the name suggests. Press L1+X and the player on the ball will make a pass. Its up to you what
to do next though, when pass is played press:
/\ for a return pass that happens to be a through pass that cuts up the defense brilliantly.
O for a chipped pass. Also excellent when defense is in the way.
X for a pass to another player. Used to decieve the opponent. Quite clever really.
Use any one that you wish. Each is deadly when used correctly. Mainly should be used between
two strikers to create holes in the defense.

Have you tried doing this in normal practice mode against no other players? It can be quite tricky to perfect this, timing of button presses/positioning of players etc
