Here is what happened in practice: 1. Any encouraging move (4♣/4♦) will get you to the OK slam, partner had: KJT9xx KQx QJTx - I don't know what happens after 3NT (but you are very unlikely to get to slam), if you bid 4♠ you surely stop there. The diamondfinesse failed, but preemptor had a singleton ♠Q (partner would probably have played for a 3-1 split), so there was nothing to the play, 12 easy tricks. 2. This is the only board where I disagree with partners bidding. I bid 4♥ and partner had: Axx 98x - AKT8xxx He bid 5♦ and we ended in 6♠. This is an OK slam on anything but a diamondlead. Maybe I should have told LHO, who didn't ask, that partner promised 1. round diamond-control :) . When LHO lead the ♦A the slam was almost hopeless, in practice I went 2 down (most people failed even in 4♠). We both stretched here, who do you think overbid the most? From partner side, if I got clubsupport or the sixth spade the slam got reasonable play and may be laydown (he knows I have shown slaminterest with relatively few HCP). 3. As expected partner is very minimum (-, xxx, Qxx, QJ98xxx). RHO got AQxxx, xx, Qxxx, Tx, so doubling 4♠ was no safe plus, 12 tricks were easy. Both 5♣ and 5♦ got some play our way, but can be defeated. John
