This hand occurred in a match yesterday, and was not bid optimally at either table:
N deals.
if you open 1♣
if you open 1♦
if you open at the 2 level
Opps had a blackwood mixup so played 6♠+1
Our auction was more interesting and I'll go into it later, but it's an interesting hand to disentangle with the void in one of partner's suits. As it happens Blackwood from the S hand tells all, but you can't really use it as if partner has an ace less, you don't know if it's the right ace missing. Had partner chosen 2N as his opening bid which he could have done (good 19-21 for us) it would have been trivial (2N-3♥-3♠-5♣(XBlack) etc)
