You sit down with a new partner and have enough time to say "2 over 1 and the usual stuff, standard carding." What's included in the "usual stuff" depends on what level you play, but for most intermediates, that includes Jacoby 2NT, Inverted Minors, New Minor Forcing, and Fourth-Suit Forcing.
That said, you have no fancy agreements. Unfortunately, this partner seems to think you have uncommonly good mind reading abilities and is making a lot of bids that you may not have thought about.
Let's see if you are on the same page when it comes to the "usual stuff".
P.S. It's sometimes easier to interpret what partner's bid means if you can see your own hand. For that reason, I have omitted your hand. You should try to understand partner's bid in the abstract rather than making guesses based on what you hold.
