If i didn't lead the 4th ( being a 2 ) with the only excuse that it would give declarer my shape (4.4.4.1) after my first discard on a lead of the singleton suit. Is that sufficient reason.

Thanks for that

Our convention card indicates the lead is 4th from longest when defending against A NT contract. In the real world Is a deviation from the CC a legal lead? If the lead is deviation from the CC and consequently defeats the contract can the director be called and what is the penalty ?
