2. At IMPs, if you can't bid 4 clubs, you have to pass. Your swing is potentially disastrous. And 3NT is absolutely insane - you HAVE to be kidding me! You don't want to lose a match over an opponent's part score bid! The style these days is to bid 3 and 4 of a suit with an outside Ace or King. Can you imagine your teammates in an IMP contest finding out you went -12 or -15 defending a part score? They would never play with you again.
3. At Matchpoints, bid 3NT if you are behind late in a match, want to shoot, and you know your partner is okay with it. It might make for a top.
You have to have enough maturity to realize that pre-empts often work. If you normally do well, you can't let them stampede you into disaster. And who says the opponents are going to make their bid?
i think you're really underestimating your chances in 3N. your opponent made the mistake of preempting. if you declare, you have a road map of the hand
