Another Precision 2 Club Auction

I had this auction today with Jason Rosenfeld--

Our auction, starting with Jason's (North's) hand was:
2C (1)-2D(2)-2S(3)-2NT(4)-3C-P
(1) Precision
(2) Relay
(3) 4 Spades, could have only 5 good Clubs
(4) Non-forcing. I could (should?) have bid 3 Hearts, game-forcing

It turned out that there wasn't much to the play--hearts makes with overtricks, 5 clubs makes and even 3nt makes because hearts were 3-3. I think that with my good spades and reasonable club fit that my last pass was a mistake, but I also didn't figure I would be facing 3 aces. I know that some people play that the precision 2 club opening promises 6 of them--that could maybe have made this auction easier. After partner bids 2 Spades I know he is 6-4 and may feel more comfortable forcing game with my partial fits. On the actual auction I did find out that he was 6-4 but also got the message that he had minimal high-cards, which influenced me staying low. Moral I guess is that if you can make a descriptive bid that may cause you to overreach, go ahead and do it in the interest of having a good constructive auction. Next time I'll go ahead and force with 3 hearts with this hand--i'll want partner declaring notrump anyway if his diamonds are something like Qx.
