The Flexible Double
I doubt the double at two level will ever be left in after opponents find a fit. I think that in a majority of partnerships, support double is off when an opponent bids 2S or higher, so I would interpret a double here as showing some extra value without a ...
Unintentional Bluffing
Using tabs for alignment is easier, however, you need to draw the hand diagrams in a text editor, then copy-paste here. See my test below.
Unintentional Bluffing
This is just to test formatting. [code] AK4 A765 QJ3 Q98 QJ98 765 [/code]
Unintentional Bluffing
Passive defense beats 4 easily -- you have three sure tricks in trumps. They can set up only one club trick for diamond discard and will have to lose a diamond.
Pass vs Redouble after 2!C - X
After an opponent opens 2, the primary goal should be to preempt them out of a comfortable game or slam. With a long suit it could be more productive to just bid a major at three level or a minor at four level. A double might help the opponents ...
BBO Cracks 52,000 Concurrent Users
When user count reached 30k late last month, there were a lot of problems with connectivity and latency. There has been steady improvement since then, and I have had no problem this month other than with their delay in reporting masterpoints from Individual SYC games. Yes, a one-month delay in ...
Flighted games on BBO
I got a surprise in SYC pairs last month. I had 400 master points. With a partner who had 160 MP we were put in B. With a partner of 1630 MP we were put in A. Partners thought I must have done something wrong.
David Liu's bidding problem: --- JT76532 K7542 7
Your table estimation is close https://web3.acbl.org/club-table-count/?year=2019&type=R&state=CA I have data to support my claim that our club was among top-ten in CA. My 70% games are rather unexpected. My first was with Alyce Jackson. The 79% with Jo was our third ...
David Liu's bidding problem: --- JT76532 K7542 7
70% games depend on some fluctuations, which happen a lot more in smaller sessions or fewer boards, such as the 299er. The big board requires at least five tables and 20 boards for that reason. On BBO we play 12 boards per game, thus 70% games are rather common.
