Do you offer Law 25A when the offender says nothing about wanting to change?
1C (P) 1S (P) 1S (P) "TD - partner's 1S was insufficient"
Before ruling that the auction stands should we ask opener about the (second) 1S bid? Should we ask if 1S was intended?
1C (P) 1S (P) "stop" 2S "TD - not a stop bid"
Before ruling that 2S bid stands, and there is unauthorised information from the "stop", should we ask opener about the 2S bid? Should we ask if 2S was intended?
