East had a chance to make a takeout Double of spades at his/her first turn to call and did not. This is UNEQUIVOCALLY a penalty double in the absence of a VERY RARE yet clearly discussed partnership agreement otherwise.
To those who think it is takeout now - or even useful as a takeout - I ask: What possible hand (that could not find an unusual 2NT overcall at the first opportunity or cannot raise hearts now) would justify that action over a partner who may simply be balancing protectively?
I reply as someone who voted for penalty but does not see it as unequivocal. W balanced with hearts. If E does not have harts this easily explains the non-double at East's first call. If this later double is to be take-out, I think E needs to not have hearts, to have the minors, but not have such a minor two-suiter as to be suitable for 2NT at his first call. A 2=2=5=4 hand would meet these requirements. Of course playing in a 4-3 club fit at the three level is unappealing but that could be dealt with by playing that, after East's double, a 2NT call by W asks E to bid his longer minor. That would work some of the time at least.
I do agree that if not discussed, penalty seems most likely.
Meta-agreements are useful. I suggested "If it could be natural, then undiscussed it is natural". Of course another would be "If a double at the 1 or 2 level is undiscussed, it is for take-out". For me, this in the main thing. Unless you are Meckwell, playing together for forty years or so, you have undiscussed sequences. A pair needs to have ways to resolving that "whatsit" question. Meta-agreements won't always solve this but they are a good start.
In the case at hand, if EW have not discussed it, I believe a pass by E would be a fine choice whatever the actual intent of his double was. The double is only going to be effective if partner understands it.
From the recent BBO forum tourney:Various opinions were collected from around the table about the nature of the double and what shall be West's consequent bid. To sum them up: it might not be obvious that it was intended to be a penalty. Could be competitive with minors and 2 hearths, since, the rewards of playing take-out doubles is greater, moreover since partner will balance often so you get the benefit of passing that take-out double as well. However, this approach deprives East from a penalty. Clearly, there is a need for some consensus about an apparently standard situation.
