Hi Jack
I am glad you like the format, which is not really new, but it is new in IAC.
However, all IAC rules apply and therefore prompt alerts are expected. The 2S bid is clearly week, and as it was not opened as such, either suit is very weak or player had 4 of other major, or hand just did not classify as good enough to bid 2S in their opinion.
Can you show what they had and what would u do with that holding?
