the reply "No information available" I looked at the players systems card No info. I then sent a PM via chat to the player asking for clarification. No response Of course I knew the bid
was Blackwood but which one? Simple or RKC? When no reply was forthcoming I summoned the TD and gave the reason. I got no response from him either!! The board was played and the vulnerable grand slam made scoring +2220 When I sent a message of complaint to the TD it developed into an online quarrel which resulted in me being blacklisted.

My gripe is this,should a player be allowed to use a convention that does not show on their systems card?. That's the whole purpose of these cards;to give as much information about a
pair's bidding system,conventions,agreements,carding methods etc. I honestly feel I got a raw deal over this matter. I also dont think that certain TDs on this site should not be TDs.as they should be able to deal with any situation which arises at the table.
A Tournament Director is like a referee. As such they should have a perfect knowledge of the rules and procedures. In this case, the Laws of Bridge. In a real time game,when a dispute arises at a table,the TD is summoned and,taking a copy of the Laws with him,he heads towards the table in question. After hearing both sides of the dispute,the TD looks up the relevant Law and reads it out aloud. If this does not satisfy both sides,the matter goes to appeal to a card committee for arbitration. This doesn't happen here for some unknown reason.
So I have two questions
1) Is a player allowed to use conventions that are not on his/her systems card?
2) Is a TDs ruling(or lack of it in my case) final or can it be appealed and,if so how does one go about it?
I await any replies with interest.
