negative freebids

BTW i don't know what it means, but the weak jump shifts to 2M are WAY more successful on BBO. Over 1.25 imp with an SEM of only 0.11

 

Of course there are negligible matchpoint results, and I havent looked at tourneys... yet.

 

I would guess WJS is more common percentage wise than on okb, but I invite you to check. Why should I do all the work?

Well I know why that is.

 

If you agree to play the OKB 2/1 convention card (possibly the most commonly played system on okb) you have agreed to play strong jump shifts. The most frequent disaster I saw over the years of playing on okb was the auction 1m-P-2M-All pass when responder correctly had a strong jump shift and opener thought it was a weak jump shift. Then there are all the auctions where opener strained to keep the bidding alive over 2M just in case it was a strong jump shift. Both players not playing the same agreements always results in bad results.

You appear (with your unproven and anecdotal data) to be agreeing with me - that in an environment unperturbed by the effect you stated, that in fact the trend I noted for the okb data is real, then.

 

It's a lot more real with the BBO data.

 

More anon.....

I agree that the auction 1m-jump shift is less successful on OKB than on BBO.

 

I do not agree that weak jump shifts are less successful on OKB than on BBO.

 

Sadly Stephen, you don't seem to understand the difference between those two statements.....
