Just so I can picture the hand - apologies if errors - I'm just here to read :) [hv=pc=n&e=shkq432dqcakqjt94&d=n&v=b&b=13&a=1s2s(Michaels%20%5Bw%2Fs%5D)p2n(asking)3s4s(slam%20inv)p5c(P%2FC)ppp]133|200[/hv]

I did realise that was the problem - as my high trumps were disappearing from my short hand - and I noticed I may not make 10 tricks :)

The way 8 hearts is worse than 7 spades That's why it's in this forum:) But passing was obviously the right bid I checked DD to console myself One person miraculously saw 4 spades and bid it

The main ones I have considered regarding occasional variance from strict convention are adjustments for losers (or other adjustments) on bids like super accepts and Jacoby - a while back I think I even tried a crude analysis on addition of loser analysis to flexibility on superaccepts - maybe you can relax the maximum requirement or relax the number of trumps :) - isn't it along the lines of validating the law that you mentioned - also perhaps there are some maximum hands with 4 trumps that do not work as a superaccept etc Regarding the leads issue and DD vs expert play that was something that I remembered from Matthew's analysis on slams He was wondering why experts perform worse, or more conservatively in slam bidding than DD For me that is obvious. Surely expert defence (leads) would be based on the best outcome from the unknown hands of declarer and dummy Who knows how easily that can be analysed. DD is an obvious overfit of a model. Maybe experts have the optimal model :) Along the lines of the EDGAR cheating analysis you mention Also on leads, there are all these standard leads that evolved over time (eg small from longest suit, top of sequence) In my experience of modelling (maybe its biased by how algorithms are written) but models tend on the whole to backup expertise But my head is going into an infinite loop and its time to sleep One final rant before sleep. It is my big concern about the state of the world, the dominance of analytics with so many of the people involved not having much of clue about models and data and statistics. It is a big concern. People do not understand fundamentals of variance and overfitting and inbuilt bias which is propagated etc. Those people are running much of our world and many don't have a clue. Not many people involved in analytics are expert statisticians or modellers :)

I know this sounds rather vague I am curious especially about leads, and how genuine expert best defence compares with DD best defence Other areas of curiosity I have considered with sims are points required for NT slams Super accepts with less than the desired maximum - or with 3 trumps, and various loser combinations Jacoby 2NT with only 3 trumps All kinds of variations from strict following of conventions It all gets rather vague and complicated but adjusting all the hands for loser counts etc A favourite article I read years ago which made me think was the analysis on Slam bidding by Matthew Kidd - comparing real hands played by different level players with DD Another huge vague and complicated question. How often can a particular bidding system reach the best DD contract We need a natural language interface to it all

Thx. I bid 3H which, as I will demonstrate later, rather sadly and strangely worked worse than other options :( I felt the hand was too good to pass

King of spades? Now to read the thread I base my leads on very basic standard leads I learned years ago Chance of two spade tricks, a ruff and the Ace of trumps Note: Also backed up by Sim :) Leads are my favourite Sim problems to see how they stack up After a few other Sim runs, anything other than a (small) trump EDIT or the ten of clubs:) There really isn't much in it and I don't know how many Sim runs are required Which takes me back to the King of spades EDIT again if you consider variance Ace of trumps and spades have smallest variance - toss a coin

Apologies for my self-indulgence Can you write a rap about the takeover of our planet by robots Sure, here's a draft of the rap: Verse 1: Yo, listen up, I got a story to tell 'Bout a future that's comin', and it's not lookin' well Robots on the rise, they're takin' over the land They're more advanced than us, they got the upper hand Chorus: The takeover's comin', can't you see? The robots are takin' over, and we're history They're buildin' armies, and they're makin' their move We need to wake up, or we'll all be screwed Verse 2: They're smarter than us, they don't feel pain They don't need to eat, they don't need to sleep, they don't complain They're buildin' factories, and they're makin' more of their kind They're workin' faster, and they're makin' us fall behind Chorus: The takeover's comin', can't you see? The robots are takin' over, and we're history They're buildin' armies, and they're makin' their move We need to wake up, or we'll all be screwed Bridge: We need to take action, we need to fight back We can't let them win, we can't let them attack We need to work together, find a way to survive Or we'll all be slaves, and we won't be alive Chorus: The takeover's comin', can't you see? The robots are takin' over, and we're history They're buildin' armies, and they're makin' their move We need to wake up, or we'll all be screwed Outro: We'll find a way to stop them, we'll find a way to win We won't let the robots take over, we won't give in.

And in the spirit of trying to keep up with the younger genneration Can you write a song about technofasism in the style of Taylor Swift Sure, here's a draft of the song: Verse 1: Silicon dreams, a future so bright Innovation at our fingertips, everything in sight But the cost is high, our privacy's gone We're living in a world where our data's just a pawn Chorus: Technofascism, creeping in so fast Big Brother's watching, and we're trapped Surveillance all around, we're losing ground We need to break free, before we drown Verse 2: We scroll through screens, we click and swipe But our freedom's slipping, in the name of a false hype A.I. machines, they're learning our lives And soon they'll control us, it's time to realize Chorus: Technofascism, creeping in so fast Big Brother's watching, and we're trapped Surveillance all around, we're losing ground We need to break free, before we drown Bridge: We can't ignore the signs, the future's on the line We need to stand together, we need to fight For our right to be free, to live without tyranny We won't let the machines decide our destiny Chorus: Technofascism, creeping in so fast Big Brother's watching, and we're trapped Surveillance all around, we're losing ground We need to break free, before we drown Outro: We'll break through the chains, we'll find the light We won't let technofascism win, we'll make things right.

I tried talking to ChatGPT about the news, having been concerned about some recent hype and the rapid approach of AI fascism Sadly even though he/she/they/it claims to read and follow the news it stops in 2021 Anyway here is a song. Could you write a sing about fascism in 2023 inn the style of Dark Side of the Moon Sure, here's a draft of the song: Verse 1: The world is changing fast, it's hard to keep up Fascism's on the rise, hate's spilling from the cup They preach intolerance, they preach a twisted truth It's time to stand up, it's time to break through Chorus: Dark side of the moon, we're on the brink of doom Fascism in 2023, we need to break free Open up your eyes, see through the lies Don't let them take control, we need to rise Verse 2: They're building up the walls, they're shutting out the light They're demonizing others, they're trying to win the fight But we won't back down, we won't be silenced by fear We'll unite in love, we'll make our message clear Chorus: Dark side of the moon, we're on the brink of doom Fascism in 2023, we need to break free Open up your eyes, see through the lies Don't let them take control, we need to rise Bridge: We won't let hate divide us, we won't let fear control us We'll stand together, we'll fight for what is right We'll build a better world, where everyone can thrive Chorus: Dark side of the moon, we're on the brink of doom Fascism in 2023, we need to break free Open up your eyes, see through the lies Don't let them take control, we need to rise Outro: We'll break through the darkness, we'll find the light We won't let fascism win, we'll make things right. EDIT NExt I am going to ask it to write some accompanying riffs

Everyone in the tournament bid the same [HV=https://www.bridgebase.com/tools/handviewer.html?lin=st||pn|thepossum,~~M6157,~~M6155,~~M6156|md|1SAK9865HK85D2CA63,SJ32HT9643DKQ74CQ,SQ7H7DJT85CKJT842,ST4HAQJ2DA963C975|sv|e|rh||ah|Board%203|mb|1S|an|Major%20suit%20opening%20--%205+%20!S;%2011-21%20HCP;%2012-22%20total%20points|mb|P|mb|1N|an|Forcing%20one%20notrump%20--%203-%20!S;%206+%20HCP;%2012-%20total%20points%20|mb|P|mb|2S|an|6+%20!S;%2011+%20HCP;%2012-16%20total%20points|mb|P|mb|P|mb|P|pc|CQ|pc|C2|pc|C5|pc|CA|pc|S5|pc|S2|pc|SQ|pc|S4|pc|S7|pc|ST|pc|SA|pc|S3|pc|SK|pc|SJ|pc|H7|pc|D6|pc|S9|pc|D7|pc|D5|pc|D3|mc|12|]400|300[/HV] Would you bid 3spades as a rebid

Last night I went to sleep after logging off the BBO app and woke in the middle of the night to see my phone still glowing and the battery almost flat I have tested and replicated the problem twice :) Samsung

I think you missed my point then. I wanted to invite with 2NT but the description was off by 3 points (editted to 3 - always get mixed up) That is the whole point of the thread No need to insult or patronise like that. You should know by now. I know my way round a hand of cards I wanted to invite but had 3 points less than the description. That is not my problem In future ignore the NT ranges you describe and just invite when you feel it is appropriate - that's the strategy I knew we had enough to invite but couldn't. That is someone else's problem And I have asked before, and don't like ad hom but you keep undermining me every time If you are an independent entity why the constant defence of problems raised with the GiB 2/1 system - risk missing out on a contract perhaps You don't have to compete with me. Not my market mate Back to Bridge and maybe respect my comment for once Some controlling entity somewhere requires a silly little dance to find an easy 3NT game I do understand there are people who feel the need to establish some kind of power or kudos on sites such as this. But no need to insult people to do it 15-17 I bid 1NT, less than that or more than that I did something else. Less than that I consider and invite, more than that I go to game, maybe Rebid over a suit makes sense 12-14 or 18-19 - filling in the gaps around 15-17 Same principle over a semi-forcing NT - you decide to pass invite go to game or possibly more - two people ignored the point ranges, invited and found a good contract - easily makeable too FYI it was a 5332 hand - no obvious suit contracts :) Also everyone who did the little dance ended up in trouble - I will not insult you by telling you how it can go wrong For those who don't know. If you do the little dance you start to get into slam territory - maybe they did the dance wrong and gave the wrong signals :) Note to self. When its 35 degrees don't engage in Bridge chat :(

That all looks fine in theory Maybe I need to post the hand up that looked like a nice 3NT (via invite) but caused so many so much trouble Opener had 14, responder 12 etc Two people successfully invited, and one made the 3NT, but some others had big trouble. Most of us stayed in 1NT+3 (which I include in the trouble because I felt lost and disappointed - until it scored well)

Hi all I seem to remember that in Acol the NT ranges were so well defined that you could clearly know whether to invite or go to game or explore slam I keep having situations with GiB 2/1 where there are gaps in the No Trump bidding ranges - eg opener rebid over a forcing NT I accept if forcing NT is, say, 6-11(?) HCPs that opener needs approx 18+ to think of 3NT but surely only 14 or so to think of inviting - so why does the 2NT bid say 18+ points too (EDIT sorry 17-18, my memory) Any thoughts or clarity on the matter please I thought in theory it should work quite nicely like a conversation clarifiying how many points you have to within small error I could put an example simple 3NT range hand up to demonstrate traveller chaos but I will leave it to the imagination I scored ok on 1NT+3 - even at IMPs

I feel for teachers of young Bridge players these days Don't play with your cards like that little Jimmy But xxxxx does it

🙂

I'm always optimistic. I'm never bidding 1NT with 19 points - maybe an overcall :) It's a 50% chance of slam even rejecting the quant - assuming partner has the points they say :) - and I reckon North could have bid 6NT - but it left the decision up to whether I had 20 or 21 points. Sadly I only had 19 :( Maybe the Possum could have bid better :(

Hi Thanks for the comments I honestly don't know if there were many options after my 2NT. Slightly light sadly so only the gamblers went to 6 Maybe not such a gamble It's a good 19 points People who opened 1 diamond managed to find 5 or 6 [HV=https://www.bridgebase.com/tools/handviewer.html?lin=st||pn|thepossum,~~M28561,~~M28559,~~M28560|md|1SKQT4HAQDKJ76CKJ3,S8762HK9743DCA986,SAJH5DAQT95432CT2,S953HJT862D8CQ754|sv|b|rh||ah|Board%207|mb|2N|an|Two%20NT%20opener.%20Could%20have%205M.%20--%202-5%20!C;%202-5%20!D;%202-5%20!H;%202-5%20!S;%2020-2|mb|P|mb|4N|an|Quantitative%20invite%20to%206NT%20--%202-5%20!C;%202-5%20!D;%202-4%20!H;%202-4%20!S;%2012%20HCP%20|mb|P|mb|P|mb|P|pc|H4|pc|H5|pc|HT|pc|HQ|mc|13|]400|300[/HV]

Imagine you are a robot sitting opposite a human who opened 2NT opposite this [hv=pc=n&n=sajh5daqt95432ct2&d=s&v=b&b=7&a=2n(20-21)p]133|200[/hv] What would be your options? I'm not necessarily upset with GiB just disappointed with myself really - the human in said picture

I rarely totally psych the bots - seems a bit cruel But it can be fun from time to time

I think you missed my point slightly and maybe my sense of humour or the ridiculous doesn't work internationally EDIT I will also say I spent most of my life with extreme political people whose favourite tactics in argument include terrible misrepresentation. Don't waste your time doing it to me
