So at worst 1S-2C is 1552?

Not sure I like the 2-way nature of the 2D response though it would frequently work out. Have you run it through the 24 hands? I'd be curious to see how it does.

Yes, 1552 is forced to bid 2

♣.

Compare to your method this wins on 19 and possibly 1/7/13

loses on 6/24 and possibly 23

Seems that it is good for thin games?
