Also if declarer has K9 and partner plays the jack from J43 thinking we led from KQT9 with declarer holding a singleton 2.
Of course if we never made leads that could potentially backfire we would be missing out on some opportunities much of the time...
On the bidding, what is the advantage of bidding 2H with a weak hand and 5 hearts with double showing constructive values against 2H showing a good hand with 5 and double a possibly weaker hand with hearts or a good hand with 4 hearts? Is it really more important to show the weaker hand with 5 hearts immediately?
My view is this:
2
♥ over 1
♥ is natural, usually 5+ and limited....this is critical....it is NOT a 'good' hand...it is a constructive, non-invitational call.
Double, otoh, is natural, 4+, penalty of 1
♥ should they play there, and
unlimited.
That is the key. I know that these days many players will have rarely if ever encountered a psychic response in a major, but such can happen, and should your opps realize you can't handle the call, it is even more likely to happen. Exposing psychic responses is not the main reason for this approach, but it is one factor to consider (as with (1
♦) x (1
♠) x being penalty as opposed to takeout...I have seen a lot of players think this should be takeout, and they are just asking to be psyched against)
You need to be able to handle hands that are forcing or invitational to game and which hold 4+ hearts. You cannot play that 2
♥ includes everything from constructive to game force....you cannot make the same bid with such a range of strength because the call may end the auction.
So we use double....after all, if this ends the auction, when we have invitational or gf values, we are likely to be very happy...they are going at least 500 and usually 800...in reality, the double never ends the auction, and we get another chance to bid and thus describe our hand. Double therefore simply says: opposite a minimum takeout double, I expect to beat 1
♥.....I may have just enough to do this, or I may have better or even much better hands.....
