Double Dummy 12

What can we learn, if anything, from this deal, which tells us that Deep Finesse can make 4S EW but not 4H! So, what’s the difference? When you see the deal for Board 5 you’ll see little difference between the hearts and spades: both have a 5-3 fit but there appear to be two heart losers and only one spade loser. Yet, DF says EW can make 4H but not 4S. Let’s see if we can work out why, then, 4H makes but not 4S.

Double Dummy 11

This deal was reviewed in my previous article but wasn’t done explicitly enough and needs some more analysis.

Double Dummy 10

As South, how would you play 4H when West leads the four of clubs? Let’s say South has opened 1H and West has bid spades quite strongly. We can look at the full deal to make the problem into another double dummy one.

Double Dummy 09

Double dummy problems seldom arise in part score situations, because there are too many variations to go through, but this one is worth taking a look at.

You are sitting West and North opens 1H and partner doubles. South bids 2H. Do you bid 2S or not?

Double Dummy 08

Few declarers made twelve tricks in a 4H contract on Board 18. Needless to say, there were none in 6H which can be made, if you have the help of Deep Finesse.

Monday X-Clubs provided this ‘double dummy’ problem The problem is: how does North end up in 2H after East opens a weak 1NT?

Roman Key Card Blackwood

Normal Blackwood 4NT or even Gerber (4C) will work well enough in most situations but there will be times when the RKC asking bid is crucial to being able to find the best final contract, which of course will nearly always be a slam, though sometimes it may be a five level contract when you find that a slam is unlikely or even impossible.

Double Dummy 06

Earlier, we saw how EW can best defend a 1NT contract given ‘double dummy’ vision. Now let’s look at what might happen if WEST is the dealer and opens 1NT, which is passed out.

Double Dummy 05

Before we start reviewing ‘double dummy’ problems from play in 2024, I would like to take another look at an interesting deal that I have reviewed some time ago, because it features one of my pet ‘likes’, the opening lead of an ace from specifically AQx against a No Trump contract.
