It's a "Spanish" + "Flare". The player bringing up the ball passes to 5, then the pivot comes up to set a central direct screen. The wing on the ball side sets an indirect screen on the pivot who sets the screen.
STEP 2
The player with the ball uses the direct screen to attack the paint, the pivot rolls inside the zone taking advantage of 3's screen, 3 opens after setting the screen, and on the weak side 4 performs a flare (indirect screen for an outside shot) to 2.
STEP 3
Several finishing options are generated: 1's shot taking advantage of BD, assist to pivot 5, pass for an outside shot by 2 or 3.
