A situation came up at the club today on the following partial auction
RHO Me LHO Partner
1♠ 2♦ 3♣ 3♦
I alerted partner’s 3♦ call, and later in the auction LHO asked me to explain same.
When I explained it as “a diamond raise denying the A or K”, LHO remarked that partner’s call was not alertable, and RHO added that it shouldn’t be alerted as the alert might “wake up partner”.
Leaving aside the issue of whether or not opponents should be telling other players at the table what is or isn’t alertable, most players at the club do not look at their opponents’ convention cards, and would not be aware of the meaning of the 3♦ call. That puts me in the position of having information that they do not have, and
even if the ACBL does not require an alert (is this true?)
even if opponents should look at my convention card but don’t
I believe I have an obligation to alert them as to the 3♦ call.
Opinions on this will be appreciated!
