I've discussed this with a couple people at my local club and I'm trying to figure out what would work best for my regular partnership agreement. I'll definitely need to justify the proposed system. So here are the basics of the two I'm a bit familiar with.
First: 1NT (P) 3H is invitational with 5-5 in the Majors and 1NT (P) 3S is game force and 5-5 in the Majors
Second: 1NT (P) 3H is singleton or void in Hearts, exactly 3 Spades and either 5-4 or 5-5 in the minors. 1NT (P) 3S is singleton or void in Spades, exactly 3 Hearts and again 5-5 or 5-4 in the minors.
I'm quite new to this conventional bid so if I have something wrong let me know. I started reading online and it looks like their are other systems out there. Generally, I like the first system because of it's simplicity, also the second system doesn't seem like it would come up very often. Insights are appreciated, thank you.
Note: we play 1NT as 15-17
