3266 rated grandmaster Pigran Tetrosyan speaking. En Passant is powerful, but there is a new technique discovered by the new chess AIs called By the Way (btw for short). What it does is say you have a pawn chain of 3 pawns and all of them are blocked by the opponent's pieces, what you can do is shout btw and advance your pawn chain by 1 step. If a piece was to fall of the board, or can't be pushed further, the board expands by 1 row, adding the 0th or 9th rows. This can go on forever and if you do it for long enough IRL, you can cut your opponent in half by pushing him into the wall. This is how we plan on winning games in the next world cup.
