When I play as a runner, I tend to be apprehensive about unrezzed ICE unless I have a breaker of each type and a pile of credits. Naturally, neither of those things are in place early in the game, and some decks might not even be able to get all 3 breaker types out during the play (if they even exist in the deck).
So far, I've played the core Shaper deck a few times, as well as the core Criminal deck once (fun fact, the only way to break code gates in it is with Crypsis or bypass with Femme Fatale, both of which seem very expensive). I'm trying to keep the pool of cards small so it's less overwhelming to keep track of which cards do what. So, I'm sticking to the core set for the moment, although the corp decks I run against could have cards from any set. I am starting to look at decks that others have built, particularly some Shaper Dagger/Paintbrush decks (which is raising it's own set of questions, which I'll probably ask later).
So, early in the game when your rig is incomplete or non-existent and unrezzed ICE is out on the board, what are some common tactics in dealing with them? Is it usually "safe" to simply facecheck ICE early on?
