Pros

1. Flexibility: White does not reveal his plan in the opening immediately and can develop strategies according to the opponent's moves. It provides the opportunity to switch to different pawn structures and playing styles.

2. Strategic depth: Ideal for players who like positional play.

3. Center Control: Instead of directly pushing the center pawns, it provides indirect center control.

4. Surprise the opponent: Since Reti is less known than more common openings such as 1. d4 or 1. e4, it has the potential to catch the opponent off guard.

5. Low risky game: Reti is a suitable option for players who are risk-averse, offering a solid pawn structure and a safe king position.

Cons

1. Passiveness risk: If played incorrectly, Reti can put White in a passive position and give Black the initiative.

2. Leave the Center to the Opponent: Since White does not initially occupy the center with pawns, Black may have a chance to capture the center.

3. Waste of time: Some variants of Reti can delay White's development and give Black the tempo.
