prefer 1c=2d as game force
prefer 1c=2s as invite

now I can still shoot for 1c=2c as weakish.

I think that's a good structure.

A simple raise is nice to have because opener will frequently only have three clubs. The 3-level might not be a good contract if the partnership is vulnerable and has only a 5-3 or even 4-3 fit ( I might want to raise clubs with xx xxx Axxx KJxx primarily to help pd with a 3-level decision). Many partnerships don't have a simple raise available and respond 1N. When there's subsequent competition, the partnership has to guess whether to compete in clubs at the 3-level. With the simple raise as a tool, 1C-1N warns opener not to bid 3C unless he has a club suit.

I agree with PhantomSac about the extra step being useful. Still seems losing to use 1C-2D as constructive, forcing partner to 3C, frequently leaving partner more room to explore game than he really wants while giving opponents room to pre-balance. 1C-2C as a simple raise leaves both sides even more room, but without forcing to the 3-level.

Mike777's structure gives more clarity to club auctions. He's sacrificing the 1C-2S bid, but this jump isn't essential for anything in particular. Again, there's too much room over 1C natural (and that points to 1C natural being a bad use).

Mike, what do you use 1C-2H for? You could go a step further and...

2C-simple raise, uncertain about 3-level
2D-GF raise
2H-inv raise
2S-simple raise, wants the 3-level
3C-weak raise

1minor=2h=reverse flannery....a forum favorite.

I love that over 1D. Like it over 1C, but it doesn't seem as necessary.

Getting off topic, but playing Reverse Flannery, how is your structure changed after 1C-1S, 2C?
I.e. what are your 2D, 2H, and 2S continuations? Thanks.

2d=game force art.

2h or 2s of course not game force.

Seems like 2H would be artificial (or 6S/4H nf). I think I'd use 2H for GI 6 spades or something like that.

You give up a bid that can show a major to be able to bid 1♣ 2♣ weak?

I prefer 2 Spade to show spades, so that I can show more different hands with spades. The majors are more valuable then the minors...
