The Games we played during Alex's visit, plus the answer to a 3-door riddle

Last weekend Alex, Eric, and mom and dad came down to visit us for a few days! Here are some of the games we played: 

Scythe. 

The Fox in the Forest.

Codenames. 

Caverna: The Cave Farmers. 

Red Rising. 

Chief Judge of Zarahemla. 

Dune Imperium. 

Lost Ruins of Arnak. 

TZolk'in the Mayan Calendar. 

Terraforming Mars Ares Expedition.

The Shipwreck Arcana.

Viticulture. 

Crossfire. 

Ex Libris. 

In front of you are three doors. Two lead to freedom, and one leads to death. You are allowed to point to exactly one door, and ask exactly one answerable yes or no question. If you are pointing to one of the freedom doors, the guard will answer "yes" or "no" truthfully. If you are pointing at the death door, the guard will either lie or tell the truth with "yes" or "no" completely at random. What do you do?

Answer: 

Point at door A, and ask: "Does door B lead to freedom?" If the answer is yes, then pick door B. If the answer is no, then pick door C. 

How does this work? 

Well, assume that door A is the door that leads to death. In that case, you'll need to pick door B or door C; it doesn't matter what the answer is. In our solution, we picked B or C, so even if door A is the death door, we wind up scott-free. Now assume door A leads to freedom. In that case, it will tell us the truth, so we simply act as if it's telling us the truth, and thus go with door B or C accordingly. Thus, we have all our bases covered.
