I found myself in a game with someone I had never played with before. My partner was neither a beginner nor a top player. But was reasonable.
I like to keep system agreements simple - especially when playing with a new partner. But partner insisted on play Jacoby 2NT. Reluctantly I agreed - figuring it best to keep partner happy. Then it came up - second hand out of the gate. Partner opened 1 spade and I bid 2NT. I had a lovely 17 count with four spades. Then my partner passed. I almost fell out of my chair. After making 11 tricks in 2NT - I composed myself and asked:
"I thought you wanted to play Jacoby 2NT?"
Partner said "I do".
"Then why did you pass? I asked"
"I passed because I thought you forgot."
