We don't need both to happen for doubling to be a big winner. If 4H is failing partner is probably passing the double, in that case even 300 is a big win.
Also if partner bids 4 of a minor that is probably a big win, we probably have 6 of a minor (he apparently doesn't have too much in spades to bid 4m).
And of course 800 would always be a big win, we seem to disagree about how often that will happen but obv it's not the most likely outcome.
I think that analysis is fair, but we must analyze it compared to when is 4H a big win vs Xing? When we make a game vs 100 that is the big win that you are playing for, do you really feel it's that likely? Surely we will oftne just get 6 tricks on power imo, it's not like they are going to catch a good dummy
I think the most likely win is vs 300 but you need a lot of win 3s or 4s there to make up for the possible upside involved in X imo (and X will sometimes win some 2 balls when we get 500 to offset these). I think it is bidding 4H that has lower and less likely upside.
All valid points (altho I would argue that bidding 4
♣ affords a slight increase in our chances of scoring 920 compared to double)
If my only concern was that doubling would cause us to miss too many 4
♥ contracts, then I'd be happy(ish) with the double. Hoping that 4
♥ is the right target is even narrower than hoping that 3
♠ doubled, when partner passes it out, is the right target.
I didn't vote for 4
♥. I chose 4
♣.
In my view, 4
♣ should get you to the best game all the time, if you are prepared to stay in game. The main knock I see on 4
♣ is that we may not yet be finished....we can reasonably enough consider slam and we may end up too high if we do or too low if we don't.
If I ignore that issue, and I don't really think I should, then the argument isn't about defending 3
♠ x'd or bidding 4
♥. It's about defending 3
♠ x'd or playing a good game contract (ignoring 3N as not on the cards...as I said earlier, I'd pull 3N to 4
♥. If you'd sit for 3N, then that alters the dynamics a bit).
Not ignoring the problem that one might end up in the right strain at the wrong level after 4
♣ does make the double more attractive. However I still don't see it as an action I'd choose at the table. I confess that having read the responses to my rant, I don't feel as strongly about it as I did then.
Btw, I wasn't persuaded, in the least, by Phil's argument about RHO's spade length. Maybe some players robotically raise partner's 3
♠ here with any 3334 hand, with no cover cards, but I don't and I don't think it winning bridge to routinely offer 500 to 800 when partner's 3
♠ may already have wrecked the opps' constructive auction. Look at the number of posters here doubling 3
♠...why take an action that can almost never turn out well? I would expect partner to hold 3 spades a significant amount of the time, tho I concede that he'll have 4 much of the time as well.
