I know i read something about this, but cannot remember where....

It hit me this weekend while playing. When you resolve crisis cards, you have to be able to fill the requirements in order to apply the result?

For example:

The choice is given to current player between skill check or a player to discard cards.

If those players do not have enough cards to discard, then that result cannot be applied, and the skill check has to be done?

Unless it's specified, you do not have meet the requirements.

If the option is to discard 3 cards and you only have 1 card, you discard that one card, and you have fulfilled the requirements.

The only exception is for Roslin's downside, she has to discard 2 skill cards to activate a location. But for all crisis cards you discard what it says on the card or however many you have, whichever is more.

If its a 'cost' required to be then able to do something then you have to have the wherewithall to do it - be it risk a raptor, discard a card etc. This is usually where it says if you do X, then you get Y. So where the cost is required first to open another function.

If its a 'consequence' of a choice or action then you do not need to have enough to fulfill the conditions and simply give up what you can of the consequences. This is the most common option on crisis cards eg a crisis card requires the President to choose either one result or another. The choice is made, then the consquences happen afterwards.

If you have less cards than you have to discard, you got off light (and might be playing somewhat smart at the same time). There is one Crisis Card, Build Cylon Detector, that gives you a choice between dropping morale or discarding a nuke, and that one specifically states that you may not choose the nuke option if you do not have a nuke remaining. If there are any others, I can't think of them.

This is actually mentioned in the rules, p.30.
