How can one easily learn chess board coordinates? I am relatively new to chess, and I wonder, what is a fast (and hopefully easy) way to learn chess board coordinates? This is so when I am watching a video where the commentator says, for example, &quot;Knight f6,&quot; I know to look quickly at f6, and I don't waste time looking for coordinates on the edge of the board or count it.
Some websites offer "coordinate drills". I'm not sure how effective they are for learning, but you can certainly give them a try. I found it to be surprisingly entertaining to try to beat my personal record number of coordinates per minute (or whatever the time limit is). Here are the two I know of, but maybe there are others (and maybe there are apps, as well):

Personally I've found that studying openings (and to a certain extent, checkmate patterns) helps learn coordinates because you start associating coordinates with certain moves, which gives each square its own "personality". For example, c4 is not just c4 anymore; it is the square where the bishop goes in the Italian game, or where the pawn goes in the queen's gambit.
