Just thinking about what you said about psychology of bidding something because you think that oppo won't want to make the "obvious" lead, a couple of things to point out: 1) I suspect a lot of players won't think about it in those terms and if your oppo aren't likely to think "I mustn't make the expected lead" then bidding 3nt without a guard in the suit that the auction suggests should be led is very risky. In short, you have to be pretty sure oppo won't make "the obvious lead" for this to work and I don't think that this is that common. I've certainly not had that kind of luck often! 2) If you don't have a guard but bid as if you do there is a pretty decent chance that the opponent on lead will have some of those cards you are missing and hence a clearer lead of the suit (ie can see you are bluffing or just knows it's a safe lead and possibly wants to knock out your guard) - you're not going to talk him out of leading from KQJx, KQTxx etc, which is a reasonably likely type of holding if neither you or p have any cards in the suit. Note that a cheap overcall of 1H over 1D was available to RHO so LHO probably rates to have the length in H. Of course, you may talk LHO out of leading from a shortish or gappy suit - there is also the chance that with that holding a H is not his natural lead anyway. Separately, I would also lead a club on that hand (presumably because I learnt most of my bridge from MickyB) because QT87 is a very appealing holding to lead from. I don't think a H lead is especially clearly indicated in the auction - west can easily have 4H, just as E can easily have 4C so I'd lead one of those suits based which holding I felt was safer to lead from/would gain more of the time.
