In "Standard American," I must open a major with 65432 while refraining from opening a major with AKQJ.
IMHO, there are five card majors that are too weak to be opened and there four card majors that are too strong NOT to be opened.
I've created a system where "An extra trump is worth a king," and the minimum opening standard is Qxxxx. Thus, xxxxxx "maps" into Kxxxx, and qualifies. xxxxx < Qxxxx and doesn't qualify. KQxx "maps" into Qxxxx and qualifies, but not KJxx, which "maps" into Jxxxx.
I'm not sure Standard American is right for me. Are there any established systems (other than Standard American) that operate along principles similar to mine?
inventnew bidding systems. You will get into systemic trouble regularly, in ways that will prevent you from effectively improving. Please, if you are serious about improving your game, choose an established and well published system and play it. I like 4-card majors, don't get me wrong. But you will need to play a system that is in common use by the better players at your club in order to improve at a decent pace. – Pieter Geerkens Apr 27 at 17:39
