Soccer Chess

All depends on your intellect, and nothing depends on luck.
Before every game, you can position your eleven players as you like.
Well, and you have your time limit - just like in chess!
1. Every team makes two following moves per turn:
Move with or without the ball (1-2 cells)
Score (3 cells maximum)
Assist (3-4 cells, also see rule 2)
Collect the ball
2. If a player with the ball is adjacent to TWO rival players, he ONLY can assist (1-4 cells)
3.If a player with the ball is adjacent to THREE rival players, the ball AUTOMATICALLY goes to the third rival player.
4. A goalkeeper can save the ball if he can occupy a cell adjacent to the one the ball enters.
5. There are no substitutes, red cards, injuries or other elements of a customary soccer stimulator.
6. Once your time is over, you lose!
