I've been that friend who was invited over to play with hosts that were really good and knew all the obscure rules. Not very fun when you discover your strategy fails because of some rule you didn't know of that they waited until you were committed to point it out.

At least half the time you get this feeling, they pointed it out with the rest of the rules and you just didn't notice.
Realistically with anything more than the most basic of games I feel as if it's reasonable to expect that the first 1-2 games are just practice because as you say, there will definitely be something that you've missed.
