I'm confused by the advice I've been getting on doubling from the column of a certain expert (Frank Stewart). In another column, he advised doubling South's one heart as West with this 14 point hand, where both sides are vulnerable. That barely makes sense to me.
But then Stewart advocates passing as West with the following 14 point hand, even when no one is vulnerable.
I would much rather double with the above hand (good spades and diamonds) than the other hand (good minor suits). Perhaps tongue in cheek, Stewart suggests that the "advancer" (partner of the doubler) mostly refrain from bidding two clubs over opener's one heart (or one diamond), and partner's double, favoring spades and diamonds/hearts instead. This is unless the club suit were at least 5 cards in length, or a four carder headed by a much better honor than other four card suits. That is, xxx in diamonds would do better opposite the above hand than xxxx in clubs, giving the doubler some leeway in having only two good unbid suits, rather than three; that is both majors or one major and one minor.
Are there any experts other than Stewart who would pass rather than double with the above hand? Or should I double more, rather than less, often than Stewart recommends.
