The opening is characterized by a slow and strategic build-up, with both players focusing on controlling the center and developing their pieces harmoniously. White aims to create a strong pawn center with d4 and c4, while Black looks to challenge it with Nf6, g6, and d5. The Ultra-Delayed Exchange Variation specifically refers to the point at which White finally decides to capture on d5, after both players have completed their kingside development.

This variation is considered to be a solid and flexible choice for both sides, as it allows for various pawn structures and piece placements. The resulting middlegame positions can be quite complex, with both players having chances for active play and tactical opportunities.

One of the key ideas for White in this opening is to try and exploit the open c-file after the exchange on d5, by placing rooks and other heavy pieces on it. Black, on the other hand, will often look to counterattack in the center or on the queenside, using the half-open d-file and the fianchettoed dark-squared bishop on g7.

Overall, this opening is a rich and strategically demanding choice that can lead to exciting and challenging battles on the chessboard. It is well-suited for players who enjoy complex middlegames and are comfortable with a wide range of pawn structures and plans.
