As Fred has said in a couple of threads recently, judgement is more valuable than a complex system. I'm a competent player but feel that my judgement is often poor, especially on wild hands.
This hand, from the recent (English) National Swiss Teams, bothered me at the time and still does now. Were my actions bad, poor or normal?
So we start with the first part of the problem - do you double (negative) or bid 3♦ (forcing)? How much do you worry about partner's next action in selecting your bid?

PS Your system is 5-card majors, 14-16NT. Opposition are on the same score as you after 10 rounds, so are presumably competent too even though you don't know them. As you gave the field a 3 match start but are unbeaten since then, you believe you are probably more competent
PPS I am noticing a disturbing similarity between sceptic and me (his mentor) in only posting our bad hands!
