If I remember correctly from my chess playing days, there was a rule that if you touched a piece, you had to move it. Fortunately, that doesn't seem to apply here since the white player is using both the queen and the bishop as a resting support. (You can't see her hand on the bishop, but trust me, it's there.)

The game has barely started, with both players moving only one piece each... but both of them were intensely focused on what the next move would be.
