whereagles and I seldom agree, but what his sentiment when he said:

"but I strongly disagree with the mainstream view that 1-level openers can occasionally be made on very strong 1 or 2 suited hands"
is indeed the quite valid. This is a principle of bidding systems like precison, polish club, Romex, etc. They create an artificial low level bid and stuff a lot of strongish hand (but the lower limit is a lot less than tradiitonal GF 2C) into it. This means, that
1H-P-1S-P-3H, and
1H-P-1S-P-3C, both have a much lower upper limit (and are thus better defined) than an tradisional SAYC or 2/1 auction that goes the same way.
This, however wasn't your problem on this hand. The 2
♦ overcall gave you the opporunity to make a GAME FORCING 3D rebid with you hand. If partner raises heart go from there, if he rebids spades, go from there. The problem bid would be if RHO did not bid at all. What would you ahve bid if the auction had been
1H-P-1S-P-?
Three hearts suffers from the same problem you had here. It is strong, it shows a good suit, but it is not forcing. So no doubt some would suggest inventing a club suit and jump rebidding 3C. Now if partener bids 3H (preference.. by the way, I have seen this 3H prefeence bid made on voids by very good players) would 3S be a.) looking for 3NT with diamond stopper, b.) Show 3 card or Hx support for spades, c.) cue-bid for club slam try. This is where muddyness comes into play, primarily because 3
♣ was used to create a force and might not (as in this case) even be a "real suit".
