...to give advice on some of their mistakes, maybe they didn't take time to look at the board. Maybe they didn't set up their pawn structure, maybe they didn't establish their bishops/knights. Didn't defend the king. Didn't line up their rocks. Maybe they gave up their knights in a closed game, or gave up their bishops in an open game. Maybe they resigned too early (I don't resign, there is usually something to learn down to the last move. I've come back from some crazy disadvantages, sometimes to people starting to trash talk...)
