1D or 1NT? My marriage is on the line...!
In Double Dummy world, It’s all on partner. If partner is in game range, that hand performs like a ‘good’ 15-pointer. However if partner has barely enough to respond to 1, then 1NT is inferior to a 2 contract. But wait … if partner is weak, then the ...
An inspiration from "size ask or clubs"
PH: I used a weak notrump framework. I simmed for hands with 6+ clubs or 6+ diamonds or at least 5-5 each, any of which would probably want to act immediately. The major constraint for the comparison with invitational hands, was the HCP range limited to 11-12.
An inspiration from "size ask or clubs"
I'm missing something. Don't you have the same 'directional double' problem whenever 2 isn't natural? And my (quick and dirty) simming suggests you'll have one or both minors about twice as often as you will an invitational balanced hand, so switching up 2 and ...
Escaping after partner opens a weak NT
Thanks. That is an improvement.
Escaping after partner opens a weak NT
The DONT double could vex. Opener starts 1NT, overcaller doubles playing DONT, which ostensibly shows a long suit (advancer usually bids 2, P/C), but is convertible by advancer. Responder has a bad hand with which he would normally run, but hopes the double has let him off the ...
Raise structure after our 1!S overcall
Transfers beginning with XX. A transfer cuebid is whatever your cuebid would show. xNT is natural, having positional value. For us, (1) 1 (X), then XX = clubs, here the transfer-cue, showing a limit raise or better 1NT = natural 2 = diamonds 2 = hearts 2 = constructive 3-fit ...
An inspiration from "size ask or clubs"
We use 2 = size ask or m, and 2NT = mm. Works fine but any time you have a dual-purpose bid, you're potentially subject to preemption.
1NT or 1C
If the opening is 1X instead of 1NT, overcaller has far more actionable hand-types. Say RHO chooses to open 1 rather than 1NT. 1 opens up (1) lightish 2m overcalls (most 1NT defences use 2m overcalls for nefarious unnatural reasons), and (2) takeout doubles of 1, the ...
1NT or 1C
Opener who opens 1NT will be worried about missing game opposite responder with 8 HCP, who passes. He should be. That hand opposite a balanced 8 (and no spade fit) makes about 60% of the time, and a little more than 60% in a 4-4 spade fit. Aces are undervalued ...
Missed game - who was more responsible
It's a valuation issue. Using reasonable constraints, that East hand performs better than a typical 18-HCP balanced hand with 4 hearts, with which East would bid game.
