Clicks are the active player's action resource and can only be spent during that player's Action Phase; a player must spend all their clicks during their action phase (they cannot spend clicks on an opponent's turn). Paid abilities are used in paid-ability windows and are distinct from taking actions with clicks, so you cannot use a click while another action is resolving and paid abilities only resolve in their proper windows (Rules Reference p5; Learn to Play p6).

You may only break subroutines during the encounter step (step [3.1]) while the encountered ice is being interacted with; any subroutines not broken then resolve one by one (Corp chooses subroutine effects unless specified otherwise) (Rules Reference p28; Rules Reference p24; Learn to Play p14).

The number of cards to access is set when access begins and you access them in the server-specific order (HQ one-at-a-time of your choice, R&D in deck order, Archives in any order you choose); cards with “when accessed” abilities trigger when they are accessed even if they are unrezzed or facedown (Rules Reference p4–5; Learn to Play p15).

The Corp can rez assets and upgrades at many paid-ability windows, but ice may only be rezzed during a run (the Corp can rez approached ice during the run's approach/encounter steps) (Learn to Play p11; Rules Reference p28).

A trace compares the Corp’s trace strength (base plus credits they spend) to the Runner’s link strength (base link plus credits the Runner spends); if the trace strength exceeds the Runner’s link strength the trace is successful, otherwise it is unsuccessful, so link must be equal to or greater than the trace to prevent it (Learn to Play p19; Rules Reference p24).

Advancing places tokens but does not auto-score; when an agenda has advancement tokens equal to its advancement requirement the Corp may score it during their turn by revealing it and placing it in their score area (Learn to Play p11; Rules Reference p6).
