1) Guide on 4 card majors. Ideally focused on the nuances that would be unfamiliar to someone who typically plays 5 card majors. A partner of mine is interested in switching to 4 card majors but neither of us have much experience with them. Would still prefer to remain as close to American standard 2/1 as possible so I've been leery of investigating ACOL books as I've heard ACOL has other differences unrelated 5 vs 4 card major openings.
2) A book on Polish Club written in English. Preferably more than just a collection of what bids mean. I've felt somewhat off balance playing against PC in nationals and would like to play it some (online probably) to get a feel for it. Feel like I'll be more comfortable playing against it once I've had a chance to play it myself some.
Thanks for any suggestions!
