Reti Opening Defensive Move in Chess

A “reti opening defensive move” is a defensive choice in the Reti Opening (often after 1.Nf3) that stops an opponent’s immediate plan—typically by controlling central squares or challenging an early threat. In practice, it often shows up as timely moves like …d5 (challenging the center), …c5 (undermining d4/e4 ideas), or …e6 (solidifying dark-square control) depending on the opponent’s setup.
