Greetings back at you from Brooklyn. NY

"i am searching a website about indoor or small field soccer tactics"
Use takeovers to play away from pressure, and to reverse your field.
The ball draws pressure if the dribbler is forced to move to a flank. As the ball moves to the flank the players on the flank are having their space killed by the approaching pressure that the ball brings.
So the flank player seeing that should leave the flank and move behind and past the dribbler to an inside the field position. Now that dribbler can use a takeover or even a back heel to that inside player who is now moving away from the pressure, and is in a perfect position to reverse the field of play to the far side into unpressure space. He can bypass the center player and go right to the far side wing mid or the far side wing back. No chance of losing the ball because the takeover player is looking right at the far side players and is unpressured.
Great simple tactic for reversing the field on a small field, even playing indoor soccer in a gym. It is a simple tactic because it only involves 2 players.
I know it works, but let me know how it worked for your team.
