Hello. Here’s what happened today - I was the dealer with SKQ, Hxxx, DAQXx, CAQJx. I opened 1 C followed by pass, pass, 1D. Then I doubled thinking I was asking my partner to show me her best suit. I was told off and offered various suggestions depending on my points. The advice was that correct bid for a good hand was 1NT and so I bid 1NT which was followed by 3 passes. On a H lead I went down.
So, was my double an acceptable bid within the rules of the game or not? What should my bid have been if any?
