Gave the Word

You decide that it would be better to just tell the word.

You give him the first word that came to your mind, Washington-3.

Your friend thinks about it and then point to the first one.

It was correct.

He points to the second one. Which was also correct.

Your friend hesitates. He then points at the last card, and to your horror, it is the assassin card, and your team lost to the other. 

You tell yourself, If only I had given him a hint.
