Valid bid explanations?
I've picked up on a few strange bid explanations in the last few weeks. Would the more experienced TD's/players care to comment if they're acceptable, or insufficient? (Noting that opponents can ask.) To me they feel like half-answers and thus potentially could intimidate weaker players into not asking further.
Assume club bridge, convention cards exist, but used as coffee-mats, laws knowledge is by experience only.
1C: Announce: "Could be as short as 1 card". Does this also need comment on why it's made, e.g. playing 5-card majors? Or should that have been done as the table sits down?
2D: Alert: Explained as "That's out strongest bid" ... and also 2C as "That's out second strongest bid". (Benji)
2D over 2C: Alert: Explained as "Relay". Surely it needs qualifying as to whether it's forced or denying certain stronger hands.
