Oft repeated scenario - GIBBO will pass and if you open your mouth will take you skyward. Not exactly applicable in this case.
Shaking and trembling started when the 3H came back to me. 3S blurb was 18+HCP. I said screw this and bid 3S. You can see the outcome.
I have no clue what GIBBO double of 3H would be or even if GIBBO bids 4H.
9 HCP opposite pard's 1NT and it is petrified and mummified.
