Red zone (M 4). It folds to you in the hijack with A♣7♣.

Red zone, folded to you in the hijack with A♣7♣. Best?

WhyOpen-shove. In the Red zone you can't play post-flop - it's push or fold. A-7 suited from the hijack is well within a shoving range; jam to pick up the blinds and antes or have a live hand when called.
What happensYou shove; the blinds fold.  Push-or-fold poker.
In the Red zone (M 1-5) you are in push-or-fold mode - the all-in is your only weapon, so jam your playable hands and fold the rest.

Red zone (M 1-5): move all-in or fold - no more post-flop play.
