BBO automatically posts an SAYC convention card in the pairs games when there is no convention card available. Unfortunately, most players have this card posted and they do not play SAYC, and no one any longer tells the opponents before the bidding what system they play or their carding agreements. In the past this was common, that is, most opponents would type we are playing pard's profile, we are playing 2/1 with UDCA, etc. With the advent of all these new players, it might be helpful if BBO added to the line saying SAYC card posted and IF you do not play SAYC you should tell your opponents what system and carding you use as soon as the round changes and you have new opponents. I cannot say for sure but I would guess that over 50% of the opponents I played against today had an SAYC CC and they played something else and never mentioned it or alerted anything. Has anyone else noticed this?
