Thank You very much for all the explanation. Now everything is clear, but it cost me some nerves when my partner didn't understand the obvious bid. Now at least I know why.
OK, I didn't know that, thanks for prompt answer, but what about all artificial bids such as Unusual 2NT, Cuebid Michaelsa? Without alert they are just natural replies.
Hi, Recently I notice that my bridge partner doesn't see my alerts at all. Nothing. I asked ops and they see everything without any problem. Can somebody help me? It is really annoying. :)
