Suppose partner had bid 2 over your 1? Now what? At the 2-level that worthless tripleton in clubs looks even more worrying. If you are playing SAYC, partner has promised 10 hcp+, is it safe to bid 2? What if you are playing 2/1? Then partner has made a game force. Now is it okay to make a reverse in hearts with this minimum hand?
The answers to these and similiar questions arise in many different contexts when your second suit is a higher ranking one than the one you opened. There is no universally agreed way to play reverses--but one thing is sure: in the absence of an agreement with partner, they are bound to come up!
