Bayhaqi 20922 — The disagreement about playing chess

Rabi' bin Sulayman (may Allah have mercy on him) said: I heard Imam al-Shafi'i (may Allah have mercy on him) saying: Sa'id bin Jubayr (may Allah have mercy on him) used to play chess from behind his back (without looking at the board), and he would say: "With what did he move such-and-such?" He would say: "With such-and-such." He would say: "Move with such-and-such."
