Watch the play. Pick what you would do. See how it goes.
Your centre-back is under pressure and rolls the ball back to you. Their striker follows the pass and is closing fast from one side. On the other side, one of your full-backs is free out wide.
Your team is stuck on one side of the pitch. Three of their players have squeezed over there, so your centre-back passes back to you. On the far side, your other full-back is standing in acres of space.
Your team is attacking and you are high, near the edge of your box. A long ball is hit over your defence. It is going to stop just outside your penalty area, and you can get there before their striker.
A through ball splits your two defenders. Their striker will reach it before you can, about 20 metres out, with one defender chasing. You are on your line.
They have a corner. It is hit high towards the middle of your six-yard box, about four yards out from your line. There are bodies around, and nobody is directly in your path.
