How do you avoid overestimating your partner's hand when they use the R.O.F?
I opened 1S and LHO overcalled 2clubs. My partner responded 2H and I jumped to the conclusion that she had 10hcp and 5+hearts. With 16 hcp and a spade stopper I bid 3NT - result crash and burn! All she had was AKxxxxx. The opponents held 3 cards to the QH and I couldn't establish her suit.
