From #5360 Robot Duplicate - Matchpoints 2011-08-08. Hand #1. All's well until West competes at 3♣ Robot North should (IMHO) honor South's Double. Yes, considering West's 3♣ bid South could hold a hand where 4♥ has a chance... but given South's Double of 3♣ South must have values in ♣'s which are wasted in a ♥ contract.

Unfortunately, the system cuts off bid descriptions at not-enough characters in myhands, but... doesn't the voluntary transfer completion show 3♥? It seems to me that the real problem is not that North bids after South's takeout double of 3♣, but that North doesn't simply bid 3♥ at that point.

OK here comes learning for me. After auction (EW passes throughout) 1NT - 2♦ - ? I admit my understanding of the 2♥ reply to be mandatory, not voluntary. If voluntary, then what is appropriate bid with poor ( ex. x-x ) holding in hearts? In a very quick search of "Jacoby transfer" the links I looked at don't explain 2♥ reply as voluntary. To georgi: I now see "robot description" of 2♥ to be: Transfer completed to H -- 2-5 C; 2-5 D; 3-5 H; 2-5 S; 15+ HCP; 18- total points; likely stop in C... Specifically "3-5H" If GIB plays this version (non-standard) of Jacoby transfer could it be shown on GIB's convention card?

Andy: When East doubled 2♦, he "took you off the hook" for the transfer; you can pass to show that you have only 2 hearts, and you bid 2♥ to show 3+. If you pass, your partner can still bid 2♥ if he thinks that's right, or he can do something else. So, a 2♥ response by you is mandatory if RHO passes, but not otherwise.
