It wasn't. I am also not familiar enough with Lauria - Versace system. Maybe 3♥ suggest hearts values (and therefore lack of ♣ values). I would love to hear the whole story. For now I am going to run the simul assuming RHO can't have K♣

Helgemo led Q♣ which as it happens with the best was the only card to beat the contract: [hv=pc=n&s=sj86ht54dt964caq6&w=s74hq9dkqj73ck973&n=s52hkj863da85ct82&e=sakqt93ha72d2cj54&d=n&v=0&b=1&a=p1sp2dp2sp2np3hp4sppp]399|300[/hv] Everything is against this choice though: -my friends polled about it choose a ♥ every time -my simulation shows that ♥ lead is the best and it's not close -his partner (Helness) probably felt asleep for a while and ducked the diamond played from declarer hand later (despite count from Helgemo) letting the contract go This was the first deal of WMSG semifinal in 2008. Norway lost by 100+imps and the play probably went unnoticed :) I dag it out from vu archives yesterday.

[hv=pc=n&s=sj86ht54dt964caq6]133|100[/hv] Opponents (Lauria Versace) bid: 1♠ 2♦ 2♠ 2NT 3♥ 4♠ I believe opener promised 6spades. Your lead ?

This is how I played. S discarded 2 and 8 of spades (making it clear he had 5 of them). What now ?

Points. We play that way only in polish club though (cause you are not forced to game opposite 8-9hcp)

[hv=pc=n&w=sj4hak85d742ckq95&e=sat7ht6dkt985cajt&d=e&v=e&b=6&a=1d1sd2sppdp2n3sdp3nppp]266|200[/hv] First trick: 5♠ 4♠ K♠ A♠ Plan at imps ?

Partner will not lead a club vs their 3NT.

I prefer style when both are 1♥'s. I am closer to passing the 1st one than bidding anything else than 1♥ on the second.

11-14 in general. Very good 14 like ATx x Kxx AKT9xxx is too strong though.

Intuitively 6D but I wouldn't be surprised if 6NT is a winner.

This in my opinion is true. I don't know how "control" is defined so I can't answer but basically defenders advantage comes from the fact that declarer needs to find all the missing honors and naturally often fails while very often next decision for defenders comes significantly later after opening lead and it's easier for them to get that right. Often defenders just wait and see with his Qxx of trumps but declarer will miss half the time... My guess is that they just got lucky on small sample of vugraph hands. I don't know anything about their style but it looks like the most likely explanation to me.

Standard dev is about 3.5imp/hand so for 250 hands sample it's 55imps (for play after 1st lead is made) For 1000 hands sample it's 110imps. For bidding (including 1st lead) it's 6imps/hand. As you can see variance is huge on those and hand samples from vugraph not that significant. It's still fun to see famous names winning on this one though ;)

And the last one which probably doesn't mean much at all: The best bidders (assuming opening lead is part of the bidding, so the double dummy result is taken after opening lead is made and this is compared to par result for whole hand). Overall those stats are influenced by variance, opponent selection etc. bu they seem to confirm some things which I think are true (that Balicki is better declarer than Zmudzinski, that Italians are the best in defence and that Balicki-Zmudzinski's weak point is bidding) (at least 800 hands to include some new players) Forrester : 440 , 819 , avg: 0.54 Drijver : 443 , 1132 , avg: 0.39 Brink : 477 , 1222 , avg: 0.39 Lanzarott : 511 , 1347 , avg: 0.38 Kirmse : 330 , 951 , avg: 0.35 buratti : 448 , 1341 , avg: 0.33 BALDURSS : 322 , 970 , avg: 0.33 Chemla : 539 , 1684 , avg: 0.32 MARTENS : 351 , 1114 , avg: 0.32 Mahmood : 624 , 2014 , avg: 0.31 Nystrom : 421 , 1368 , avg: 0.31 PASSELL : 323 , 1053 , avg: 0.31 GAWRYS : 319 , 1112 , avg: 0.29 FANTONI : 865 , 3044 , avg: 0.28 Nunes : 865 , 3044 , avg: 0.28 Hampson : 390 , 1448 , avg: 0.27 Greco : 390 , 1448 , avg: 0.27 gromoeller : 258 , 967 , avg: 0.27 Ramondt : 299 , 1141 , avg: 0.26 lauria : 1450 , 6134 , avg: 0.24 Brogelan : 422 , 1922 , avg: 0.22 Quantin : 254 , 1193 , avg: 0.21 VERSACE : 1353 , 6437 , avg: 0.21 CHAGAS : 372 , 1929 , avg: 0.19 CHMURSKI : 183 , 1008 , avg: 0.18 Lindkvis : 193 , 1087 , avg: 0.18 RODWELL : 851 , 4986 , avg: 0.17 Meckstroth : 814 , 4987 , avg: 0.16 SAELENSMI : 207 , 1270 , avg: 0.16 KOWALSKI : 189 , 1197 , avg: 0.16 Multon : 194 , 1259 , avg: 0.15 SEAMON : 186 , 1210 , avg: 0.15 Becker : 132 , 859 , avg: 0.15 FREDIN : 247 , 1625 , avg: 0.15 Jonsson : 222 , 1476 , avg: 0.15 Rubin : 138 , 933 , avg: 0.15 WLADOW : 181 , 1250 , avg: 0.14 Elinescu : 168 , 1286 , avg: 0.13 Ekeblad : 215 , 1678 , avg: 0.13 Mari : 216 , 1723 , avg: 0.13 ROSENBERG : 373 , 2980 , avg: 0.13 Zia : 221 , 1983 , avg: 0.11 Bramley : 97 , 902 , avg: 0.11 BOMPIS : 157 , 1787 , avg: 0.09 Verhees : 90 , 1025 , avg: 0.09 Branco : 155 , 1783 , avg: 0.09 Stansby : 198 , 2309 , avg: 0.09 Helness : 228 , 2782 , avg: 0.08 helgemo : 192 , 2813 , avg: 0.07 Skrzypczak : 61 , 902 , avg: 0.07 Cohen : 201 , 3010 , avg: 0.07 bertheau : 112 , 1716 , avg: 0.07 Stewart : 44 , 805 , avg: 0.05 WELLAND : 84 , 1548 , avg: 0.05 Sontag : 89 , 1855 , avg: 0.05 Martel : 88 , 1840 , avg: 0.05 sementa : 78 , 1679 , avg: 0.05 BOCCHI : 196 , 4637 , avg: 0.04 Jansma : 46 , 1184 , avg: 0.04 Manoppo : 31 , 836 , avg: 0.04 BALICKI : 57 , 1998 , avg: 0.03 DUBOIN : 129 , 5263 , avg: 0.02 WEICHSEL : 32 , 1458 , avg: 0.02 HAMMAN : 51 , 3552 , avg: 0.01 Soloway : 21 , 2205 , avg: 0.01 WEINSTEIN : 30 , 3430 , avg: 0.01 Gierulski : 4 , 888 , avg: 0.00 Berkowitz : 8 , 2797 , avg: 0.00 ZMUDZINSKI : -10 , 1842 , avg: -0.01 TUSZYNSKI : -9 , 1345 , avg: -0.01 Garner : -21 , 1701 , avg: -0.01 Robinson : -15 , 887 , avg: -0.02 Levy : -64 , 2360 , avg: -0.03 bertens : -43 , 1555 , avg: -0.03 WESTRA : -45 , 1391 , avg: -0.03 Wang : -103 , 2696 , avg: -0.04 Kholomeev : -41 , 917 , avg: -0.04 MOLLER : -42 , 934 , avg: -0.04 bakkeren : -80 , 1226 , avg: -0.07 Gitelman : -125 , 1889 , avg: -0.07 Moss : -170 , 1993 , avg: -0.09 HACKETT : -323 , 3509 , avg: -0.09 Dubinin : -149 , 1514 , avg: -0.10 Levin : -246 , 2341 , avg: -0.11 Wolff : -90 , 824 , avg: -0.11 FALLENIUS : -184 , 1518 , avg: -0.12 Schaltz : -163 , 1082 , avg: -0.15 Jacobs : -265 , 1542 , avg: -0.17 JASSEM : -212 , 1194 , avg: -0.18 Schwartz : -177 , 952 , avg: -0.19 freeman : -407 , 2164 , avg: -0.19 Katz : -256 , 1296 , avg: -0.20 nickell : -476 , 2372 , avg: -0.20 SMIRNOV : -199 , 911 , avg: -0.22 Gromov : -467 , 2099 , avg: -0.22 Zhuang : -202 , 812 , avg: -0.25 pszczola : -259 , 1023 , avg: -0.25 Muller : -488 , 1746 , avg: -0.28 Mouiel : -395 , 1344 , avg: -0.29 piekarek : -434 , 1436 , avg: -0.30 Smith : -274 , 852 , avg: -0.32 Sun : -434 , 839 , avg: -0.52 Average: -0.0009685442650556978 imp/hand so almost 0 (obviously :) ).

I think there is a lot of variance in the opening lead so proably that's why the results differ that much. On average opening leads gives away about 1 imp/hand (can't remember how much exactly now) which is more than play is "worth" (in double dummy terms) after it. Unfortunately the stats are limited by what vugraph operators put in to the files when filing up the names. I cleaned this mess a bit by joining all the 6+letter names into one category (all the stats go to the shortes one on the list and "eat" all the ones which are longer but contain the shorter) so all the: "Fantoni", "FANTONI", "Ful Fantoni", "Fantoni F." etc. becomes just "FANTONI" I also manually joined some of the shorter names ("Nunes", "Brink", "Levin", "Cohen", "Greco", "Moss", "Levy", "Wang"). This has side effect of making stats for Cohen, Hackett, Bessiss and Lall (there are 80 hands of "Lall" in those ;) basically useless becaue there are more players with this exact name. (I didn't have this automatic names cleaner when I posted first part of stats that's why Levin has less hands there) I also forgot to manually join Zia and Mahmood as you can see on the list :) I will recompile later joning all the Zia's and Mahmood's. Thanks :)

Oh, 4♣ wasn't actual bid. My partner bid 5♣ fearing that 4♣ would be not forcing. We missed a good slam and we are wondering if we had a chance there.

Imo N should've doubled 3♠ showing good hand / takeout If that would be for penalty though then I would probably gamble 3NT but I don't like it at all.

I am not a fan of 2NT at all but the blame goes to South cause 3NT isn't even remotely sane.

2♣ 2♦ dbl pass 3♣ pass 3♠ pass 4♣ imps; both vulnerable; It was actually polish club so 2C could be 5C-4M but it doesn't matter much in this auction I think. Should 4C be forcing here ? How would you bid: AKQ62 A9 T92 T84 97 KT2 7 AKJ7632 ? I had to double instead of 2♠ in first round because we play 2♠ as not forcing (but constructive) and 3♠ as forcing natural but pomising 6 spades.

After playing around with some double dummy statistics (defence vs par result, defence after first lead after par result, declarer play after first lead vs par etc.) my opinion is that the difference in card play between elite players and average Joe (who still play in Bermuda Bowl though) is huge. I can't imagine bidding make up for this.

So what does E bids with a hand without S stopper, diamond fit and not "encouraging" ? (but still GF)) This is one of the many holes in Swiss cheese which standard is but that's exactly how it is :( I think 3NT says you want to play 3NT opposite average hand not minimum. This is one of the basic principles in bidding as taught in my country at least (that you make your normal (ie not focing/encouraging or sign off) bids assuming average hand . Average is probably around 13hcp for this bidding so...

General idea (after both 1H and 1S overcalls) is: 1NT/2NT/3NT is always natural 1S is transfer to NT or clubs (opener treats it as transfer to 1NT) Jumps to 3level below overcalled suit is natural invitational. All other bids are transfers which are weak or strong. 1D - 1S - dbl is 4+hearts any strength or 5hearts 7-11 (so 2D is either 6hearts or 5hearts (almost) GF) I played this after both precision 1D and polish 1C. The idea is from Martens. I think advantage is simplicity because rules above apply to all the bids and are easy to remember.

Imo this is very simple hand and W overbid his hand after 3NT. Looks really wtf to me so I am awaiting replies which gives any justification for bidding after 3NT.

I played: dbl = 4+spades 1♠ transfer to NT or clubs 1NT = natural 2♣ = transfer to diamonds 2♦ = transfer to opponents suit, general gf/stopper ask 2♥ = transfer to 6+spades weak or GF 2♠ = clubs , weak or GF 2NT = natural 3♣/3♦ natural, invitational 3♥ 6+spades, invitational 3♠ tranfer to 3NT 3NT = to play when playing precision; We used the same structure over 1D - 1S (the club suit is sometimes lost there but there are other advantages)
