The number of rounds in a swiss should alway be less than half the numbers teams (and more than the square root of it). With 12 teams you can play either 4 rounds accelerated swiss (1 vs. 2 in first round) or 5 rounds with last round danish (1 vs. 2, even if it is a rematch). yvan

starts tomorrow: http://www.worldbridge.org/tourn/Beijing.12/Beijing12.htm Any idea how the teams were selected ? yvan

Agree, but I was just trying to show how easy flawed dealer can be detected. yvan

Agree and disagree. Testing is not that hard. The "too many voids test" is easy, as is the "too few singles test". Average, about one of five boards have one or more void, one of five have no void of single. If you frequently have more than 25% of the boards with one or more void (or more than 25% of the boards without any single or void) your program is probably faulty. Here are my stats for "super unbal boards" (P1V) and "super balanced boards" (PNS): For 32 Boards : P1V : prob. of exacty N boards with one or more void PNS : prob. of exactly N boards without a single or void N P1V TP1V PNS TPNS 0 0.16% 0.16% 0.06% 0.06% 1 1.11% 1.27% 0.50% 0.56% 2 3.86% 5.13% 2.04% 2.60% 3 8.65% 13.78% 5.31% 7.91% 4 14.05% 27.82% 10.03% 17.94% 5 17.63% 45.45% 14.63% 32.57% 6 17.77% 63.22% 17.16% 49.73% 7 14.79% 78.01% 16.61% 66.35% 8 10.35% 88.37% 13.53% 79.88% 9 6.19% 94.55% 9.40% 89.28% 10 3.19% 97.74% 5.64% 94.91% 11 1.43% 99.17% 2.94% 97.85% 12 0.56% 99.73% 1.34% 99.19% 13 0.19% 99.92% 0.54% 99.73% 14 0.06% 99.98% 0.19% 99.92% 15 0.02% 100.00% 0.06% 99.98% 16 0.00% 100.00% 0.02% 99.99% PS: As someone else wrote, they wont believe it. yvan

No need for simulation, it is really simple math. I am with wyman with different notation: West 5332 with DJ = C(2,5)*C(2,6)=10*15 West 5323 without DJ =C(2,5)*C(3,6)=10*20 so finesse =4/7

I disagree. Encourage commentators to use GIB, and explain. I prefer comments like: "of course, double dummy, it makes on a H-D squeeze, but the finesse looks like the percentage play" to comments like: "one down" or "cold now"
