This is the hardest thing for young players to learn and execute against pressure. While a simple concept it is one of the least well executed in basketball. Basketball is a game of angles. If you run curves and allow your defender to play the shortest routes between two spots you will always be pressured. If however, you cut and move at angles, especially backdoor you gain advantage and make the defender cover more distance.
Backdoors force defenders to turn, opening the door for possible outlet cuts as the door swings.
There is no more effective weapon against pressure than ball movement by passing with well spaced offensive players and or well timed cuts. Once two players are taken out of possible outlet positions, a freed defender may trap or gamble by overplaying a dribbler without fear of getting beat. If you don't have the ball, be aware of your teammates and either cut to an open spot to present a possible outlet pass for a pressured teammate, or rotate to fill an open space vacated by a cutter to maintain offensive team spacing. While a quite prophetic statement about life in general, it is even more so true in the game of basketball. Basketball is one of the fastest changing and unpredictable games played.
