The first slam is very difficult to estimate. Slam is quite decent on a non-heart lead. On a heart lead, you can hope for trumps 2-2 and diamonds 4-3, but perhaps better is to run the heart, hoping that the opponents don't find the club shift (Justin suggested this when rogerclee was bidding the hands, I thought I needed to practice serving but I ended up not serving any of the contestants).

 

This is a terribly difficult hand to score, I'd say something like 4S = 9, 6S = 7.

 

On the second hand 6S is great on a heart lead, pretty much without hope on a diamond lead and close to 50% on any other lead. Missing KQJ of diamonds I'd say a diamond lead is about 70% likely, a heart lead is 15% and any other lead 10%. So I'd give 6S about 20% chance to make.

 

7S gets 0 matchpoints, 6S gets 1.4 mathpoints and 4S gets 2.3 matchpoints. This is on a 3MP top, so rescaling to a 12 point top gives us

 

7S = 0

6S = 5 or 6 (5.6)

4S = 9 (9.2)

 

I'd go with 0, 5 and 9.

While Han has a point about a non-heart lead, 4 is better than slam. I agree with han's rating for 4 (a 9), but I think the 6 score he suggest is too high. I rated 6 as 4. With this scoring, TylerE-bidemup stretch their lead.

This is a hand where I thought the best slamwas clubs. But a the pairs -- perhaps pushed by matchpoints -- all stayed in spades. However, the best contract is Notrump (it makes 5NT easy enough). If we agree that 3NT is the best spot (a 10 I think), and that from among slams, 6 is the highest scoring (I have it at an 8 point).

 

We will start with 7, clearly it is not making, and should get a poor score. 4 is a very safe contract, and will make, with an overtrick (unless someone ruffs a club at trick one). The question is, how will 6 do? It can make, but only rarely, needing a non- at trick one and the King with EAST. If we eliminate a black suit lead, it is at best 25% to make. So we can rate this as a 3. Of course, 7 has no chance, and I rate that as 0.

 

5N = 10

6C = 8

4S = 6

6S = 3

7S = 0

 

On this hand two pairs moved closer to TylerE-bidemup, but the TylerE pair is still ahead.
