Okay, even if you forget your system, still lead your good 6 card suit against 3NT.
Kx, Qxxx, KJTxxx, x. both vul, I opened a 3rd seat 2D, alerted as mini-roman. the auction proceeded 3C-3H-3NT-P-P-P. And I led a heart, obviously. And now declarer has 9 top tricks. Partner has Ax of diamonds and declarer Qxx. Perhaps they would have been entitled to some redress if I led a diamond but I doubt it. Perhaps they have a valid argument that I have to lead a heart on this sequence or that partner has to shift at trick 2, "knowing" that declarer has 5 diamonds but I really doubt it. The only redress I can possibly see is being required to bid 4H, but only if partner was not a passed hand. eh.
If you led a diamond (instead of a heart), the opponents could claim you did so because of the Alert (which provided you with unauthorized information).
ReplyDeleteIt looks like you can't win here, once you opened 2D.
