Deep in the Green zone (M 25). A player opens to 1,800 from middle position and it folds to you on the button with 7♠7♦.

Green zone, MP opens, you hold 7♠7♦ on the button. Best?

WhyCall. With M 25 you're deep enough to play a normal game - flat-calling to set-mine has the implied odds and keeps you out of marginal all-ins. In the Green zone you don't gamble; you play poker.
What happensYou call to set-mine.  Normal, patient play.
In the Green zone (M 20+) your stack is healthy, so you play a full, patient game - set-mining and small-ball, not shove-or-fold.

Green zone (M 20+): play your normal game with full flexibility - no need to gamble.
