MP, robot tourney, best hand South, Traveller 9817-1373080921-60121704
2S is described as "6+S, 14-18 total points". I do not object to the explanation. I do object to the bid.
Granted that N might reasonably expect to find 4 H on his right (indeed the explanation of the X so promises), I would still prefer a 2H bid by N over 2S. I prefer Pass over 2S.
Mine was not the only peculiar auction. Other tables started the same way, but South decided to pass, and then West pulled the double to 3C, having effectively described his hand on the previous round with X. East is fully aware that West is a passed hand when deciding to axe 2S. West should respect that, in my opinion.
Not sure that I like East's X of 2N. Well, it worked, so perhaps I can't complain too loudly. I came within a hair's breadth of making, but hey, it wasn't IMPs so I let it off that one.
