For the unique query; sure, there’re quite a few situations of downgrading 11 to 7 factors, and simply as many as upgrading 7 to 11 too! Sufficient to justify a newspaper article! Though recognize journalists will often selected exaggerated instances for influence, to teach how far palms might modify, somewhat than displaying the ‘common’ corrections.
Since Frank Stewart provides the reply, his 2C is appropriate after all. His message is straightforward: don’t jump-raise except your hand actually is invitational, even if you’re over 8 factors. Simply hold bidding open for doubler to disclose further. (Naturally, Frank has fellow specialists to proofread his articles earlier than publishing so he’ll at all times be in the proper!)
What’s much less explicitly talked about is how hand form and texture get extra important with takeout doubles and a number of matches so its frequent to see bigger changes. A Kx earlier than openers seat is value nearly nothing, whereas Ax or Kx behind opener might be value further. Equally, factors going through a void or singleton are often nugatory so +/-4 revisions are pretty frequent.
When you’ll be able to look past simply ‘factors’, its simpler to see each Frank’s palms present about 9 losers after adjustment, going through a gap hand (say 7 losers) that won’t but promise a match. So, Advancer just isn’t actually value greater than a minimal response till doubler reveals some further power and a match or stopper, to recommend 5-6 cowl playing cards.
