about me

Systems builder having some opportunities to benchmark them in France, would they be highly unusual or little gadgets around standard. Convinced that Fantunes opened the path to a new way of bidding (but I am too addicted to good ethics to win).

ACBL Ranking
Sorry, this user has no cards yet.
Slow Return
My read of the Law is : Whatever the %, if this is increased with UI you can't chose it. You must chose between LA that are equal or lower. So a LA that changed from 90% to 95% is not permitted, despite being the large majority. You are only allowed ...
Slip It By
Pass double inversion is not impacting the sequence pass+pull. Whatever you play about the direct double, the sequence pass+pull should still be 2 places to play.
Comments on the CAS Report
My point is not to attribute explanation for any misplacement of card. It is to convince the jury how unusual placing a card H is. We, as bridge players, at least subconsciously, perceive how unusual it is. A jury might not. Same applies for a card holder not being in ...
Comments on the CAS Report
Thank you very much for the time you spent on this topic and further time to analyse CAS document in detail. I think we overlooked the trial issues. There was additional statistical data evidence we could have brought to back our assumptions. 1. We should have measured the probability of ...
Gazzilli over 1!D
If you are guaranteed 5+ then losing ability to stop in 1NT is largely outweighed by benefits in precision won by Gazzilli. When you are 5332 you have 2/3 chance to have 3 card support. When you are 6332 or 5422 it is unlikely 1NT is the best contract.
Gazzilli over 1!D
I don't get it. Strong NT hands (if not all NT) should go through 1 with transfer responses for a lot of reasons. If you play old fashioned strong Club, this may become your first bullet point on system rework list :)
Gazzilli over 1!D
Yes I am extrapolating 1 1M 1NT from the 1 1 1NT I play already. I have written the extension for 1 but it is still not validated with partner. :)
Gazzilli over 1!D
I play it Gazzilli after 1 1 with no siding issue so far. Having other ways to raise with 3 or 4, you will usually be short so most likely correctly siding minors. Same should apply for 1 of course.
Is it really just 37%?
You are lucky there are always 4 cases for each of the given examples Jx Tx JTx with x varying in 4 values. Each unit case is worth 1.6 or 1.7 (I had 10 of those in my example). Multiply your % by 4/10 and you are ok.
Is it really just 37%?
Yes I fear most people mess up in the reasoning. Quickly said: * when opponents follow suit you don't really win information, you only discard some distribution and zoom in the remaining ones. * from other suits the most useful information is the known length difference (if side suit breaks even ...
