Just looking loosely at the board I can see he's controlling the center in 2 if not all 3 pictures, so he's at least got good fundamentals. Would be fun to know his rank.
I'm already keeping track of the kings and rooks for castling reasons. Remembering whether any of the 16 pawns has moved is too overwhelming and turns IRL chess into a game of who can get away with the other player's bad memory.
