You do sound very condescending, at least from my point of view. I understand you're proud of your experience and skill and that you're anxious to share your knowledge with others. But that doesn't come for free. If you want others to listen to you, you must also listen to them, in this case, me. I know I have some off-mainstream ideas about bidding, but I got to them on my own, through reading, playing and analysing. I do not have the style I have because of bad partners. (Though I confess I hog the hand and mastermind with a bad pard - I want to win, and so does HE!

)
Anyway, back to the technical points. I asked you if you played 1
♠ as forcing because where I live, most people play like this:
1m-1
♥-1
♠ = 11-17, non-forcing, may be balanced 12-14. Pard may pass with semi-fit and 5-7 points.
1m-1
♥-1
♠ = 18-21, game-forcing. Spades may be xxxx.
Within these definitions, the hand fits a 2
♠ rebid. If your 1
♠ is wider (I know some that play it as forcing), then you have an option I usually don't have. I think this clears it up. US/Europe differences, I guess.
Oh, and about I not having played with a strong pard, well, I can tell you this. I played for the national junior team some years ago, in partnership with country's strongest junior at the time. For professional reasons, I only had the opportunity to run for the national open team once and got to the quarter-finals on that occasion.
Now cheers and cya in a week (off to the beach.. ehehehhe)
