Jack moved the bishop with the ring finger and pinkie of his left hand. They weren’t using a clock so the extra time to pick up and place the pieces was of no matter, but the inefficiency irked Joe. He said nothing. It was enough to keep Jack focused on the game, to insert another idea would add complication. Jack planted the bishop on the D6 square awkwardly transferring control to his right index finger to hold it in place as he considered the move. This irked Joe as well, he had told Jack repeatedly they were in learning mode and not playing mode and touch move was not in effect.
“Jack, are you sure you want to put that bishop on D6? You are not going to be able to move that D7 pawn and that light-squared bishop is going to take forever to get out. Are you sure you want to do that?”
Jack considered and his long lean face dropped even lower between his thin shoulders, “Well, if I don’t put the bishop there, if you move that pawn up I won’t be able to defend it later.”
“Not up, chess language.”
“Uh, D2 to D4.”
“Good, or push the D pawn, and yes, I will probably play D4, but is the bishop the best way to defend that?”
Jack considered. Joe waited and then Jack’s head tilted a little and his eyes glided right and Joe knew his attention had gone that way as well.
“Chess, Jack,” Jack’s gaze came back to the board and Joe could almost see him slowly puzzle the position from the beginning.
“Well, this might not be the best move but I can’t see another way so I am going to make it.”
Joe relented and pushed the D pawn. He would crush Jack here and in the post game analysis they would go over the move and he would explain the trapped bishop. Jack would not forget, but might have to repeat the same mistake several times before he did not make it again. It was his way.
