Double of an "either/or bid"
If the overcall can be passed, you can check for your own major fit and/or stoppers with 3 'Stayman'(here, 3 shows 4h, 3 says no stopper no 4h, 3NT says yes stopper no 4h). If invitational, start with X, then if you like opener's ...
Double of an "either/or bid"
Two-under transfers beginning with X = clubs or invitational balanced, 2NT = diamonds, 3 = hearts. Opener responds min-max. Pass then X is your takeout option.
Mini & Weak No Trump
Consider an 11-14 range which increases the frequency of your openers by some 30%. Yes include all 5332 hands in 1 or 1NT, so all other 1-level bids are never 5332, and sharpens them considerably. Yes play transfers over 1, which right-sides most of your contracts. We rebid ...
1NT opening, 2S range check, 2 ways to invite with a long minor.
Another approach: 2 = range ask or any strength clubs (replies 2NT min, 3 max, responder continues appropriately) 2NT = any diamonds, min-max replies Disadvantage is that min-max for clubs is for HCP strength alone, regardless of club holding. Advantage is you now have freed up 3 for something.
Lebensohl after opps show both majors
Transfers beginning with X, with transfer into their suit being a stopper-ask. So over say (2), X = have heart stopper?, 2 = have spade stopper? 2 = balanced invite or clubs, 2NT = diamonds. Pass then X = penalty.
It's Your invitation
Just confirming to myself that in some contexts, owning aces isn’t necessarily awesome. When you and partner are sharing most of the high-card strength ... say your combined assets are in 3NT range ... a hand with no honors but aces just narrowly outperforms a hand comprising ZERO aces. Partner opens ...
It's Your invitation
Tens have value when connected, higher or lower, not so much when isolated. HTx is clearly stronger than H7x, and T9x stronger than T7x. Tx(x) would have little value. >> So just having 2 Aces and no tens, one should never invite with 4432 hands (23% making game). Correct? That ...
It's Your invitation
That is a great 8-pointer, and clearly worth an invite. Three tens is worth about a jack and a half, the two bullets all by themselves are worth more than eight. 4432 is the worst shape to have, but the doubleton is stopped. Some quick and dirty 3K sims. That ...
Bots Are Coming at You
Yes for sure. I prefer my partners not to falsecard unless it is obvious it will not lead me astray. Defense is tough enough without having to consider that partner, not declarer, might also hold the King despite winning a trick with the Ace, especially if done early in the ...
Bots Are Coming at You
I've had some experience actually programming a bridge player. I haven't looked at a line of code for a decade or so, but I do recall that although false-carding might mislead declarer, it can also dumb down the defence. It injects additional variance. If a bot defender always ...
