Event 7B (Round-robin then Knock-out) - Gold and Silver Brackets

I think this tournament (7B) went really good and the format was nice - except some people complained about the IMP/best-hand. We will open up a discussion thread for the Event 8 soon. We had several issues in the parallel event (7A) due to some players, I am actually very glad that we kept the list "somehow" invited for 7B.

 

For Event 8 (Probably will be in IMP or MP/non-best hand), I am somehow planning to combine events A & B for the earlier stage:

>> We get registrations for the Premier Event, it will be open to anyone who can play in a similar pace with Event 7B.

>> A set number of players (Group X) will directly start from Round-Robin stage, based on masterpoints list.

>> Others have to play a qualifying round - or maybe two rounds if too many entries, all numbers will be decided based on the entries - to join Round-Robin stage.

>> We put Group X with winners in the qualifying round (Group Y) and these people will play the Round-Robin.

>> For people who cannot play in this pace, or people who cannot make it to Round-Robin, there will be a Side Swiss, probably in IMPs/non-best hand (since I don't have software and stuff, the actual movement will be Danish, with multiple games between two players are possible). People who are in the Round-Robin will not be able to play in this event.

 

Any ideas? Especially about IMP/MP for the premier event?

As for the format for the next event, Id strongly prefer not to play IMP best hand, but rather some other format.

Also hope to start the finals with Olegru asap :)

I like switching between IMPs and MPs.

 

The problem with best hand is that it completely changes the dynamic of bidding and play (knowing you've got the most HCP at the table). IMPs best hand is about making game on almost every hand, with now and then partscores and slams.

phoenix214 - olegru (20 - 8)

really close set, Oleg did not get to a slam, while I decided to not try and push a game, which was making, luckily NV.

 

Hand 9 was a bit interesting, as both of us misplayed a making 4H, cause we both missed a nice endplay.

I figured my line had the nice extra chance to make if Lefty started with Kx in D, but a better line to make, is just to simply discard a club on 4th diamond, as then bot has to lead a club or give a ruff and sluff

This is true but all humans are in the same situation and the robots won't complain. So what?

 

What I don't like about non-best hand is that much of the defense play is just random. You discard 6 on one table and 5 on the other table, and you know it shouldn't matter because declarer doesn't observe signals but the random seeds now work differently on both tables, and what happens is that the robot plays the hand well on one table and misplays it on the other table. I find that tolerable when I'm defending just a few hands, but when I'm defending 50 % of the hands, it can be annoying. Particularly in IMPs against a good opponent when 3 of your 4 swings come about in this way.

It's not as bad as that. I have just checked the 64 boards that I played against phoenix214. We had

29 full games,

19 part scores,

12 boards defending,

4 slams.

I find that's quite a nice selection considering that declarer play is a very essential part of bridge.

But the defence is subject to the same random disruption when you vary your carding as declarer. The problem with best hand is it gives you information that you would not normally be allowed to use.
