Bidding has gone (all NS, playing 2/1)
1S - 2D
4H - 4NT
5S - 5NT
6S
4♥ is a splinter singleton/void agreeing ♦
5♠ is 2 KC in ♦ plus the Q
5NT is a king ask, 6S shows all 3 outside diamonds
Few questions about this hand
1. Is a splinter agreeing diamonds a good treatment for the 4H bid, we keep 3H as showing a hand with reversing strength.
2. Should I have used BW in this situation.
3. Was a King ask risky? I thought that I could duck out at the 6 level if he shows 0 or 1 kings.
4. I placed Partner with
AKxxx
K
AQxxx
Kx
Should this have been a million miles away?
I thought that if P had either the Q♣, J♠ or spades were 3-3 7NT is cold. At the table I guesstimated that 2/3 of the time at least one of these would happen so I should go for it? I did not think P would have opened 2C with 20/21 points holding a singleton K♥.
