It's not easy to rock climb around crevices as your body moves away from the rock surface risking the natural contact with the wall. I'm still learning so practice is important as one develops strategies to coordinate and master different angles of the wall.
Center of gravity should hug the wall as much as possible. Slippery sweat dipped fingers become a problem as you try try to over and around the corner and outward pressure is applied.
One must use their brains as much as their bodies in rock climbing. Don't go until you know where your 3 point contact will find solid landing. Look, feel, and maintain as much return balance as possible if all does t work as intended
