LHO opens 2♥ which shows a weak hand with 5♥ and 4+m (Muiderberg), partner bids 2♠ and RHO doubles. We were Vulnerable, opponents NV. I held:
I was thinking of raising until I found a better idea. I started to ask some questions, with the intention to convince LHO that this is a penalty double.
me: What's the double?
LHO: Actually, I have no idea...
me: What would 2NT mean?
LHO: That would be a strong relay.
me: What would 3♣ mean?
LHO: P/C for the minor
me: So it's a penalty double?
LHO: Yes I think so...
So that ended the auction. Partner made 2♠*= for a top, and RHO meant his double as takeout.
Now I wonder if my behavior is allowed or not (probably an ethical thing)... Please be honest, I won't mind.
