I always use Stayman with such hands unless the hand shape is exactly 4M-3-3-3.

Can you please write the bidding sequence using parentheses around opponents' bids? When it's written this way it's impossible to answer.

Over natural 1♣ opening (2+ cards), we play Walsh, so 1♦ bid denies 4M unless responder has at least invitational hand. Also, after 1NT rebid by opener, we play Two-way checkback: 2♣ is transfer to 2♦ which responder passes with weak hand and diamonds or bids on with invitational hand, and 2♦ is game forcing relay. Suppose you have two sequences like this: [hv=d=n&v=0&b=1&a=1cp1dp1n(May%20have%204M)2cdp]133|100[/hv] [hv=d=n&v=0&b=1&a=1cp1dp1n(May%20have%204M)2ddp]133|100[/hv] How do you treat partner's Dbl in above sequences? Is it a "stolen bid" double, or negative double or something else?

[hv=pc=n&s=skj875ht94dcakq43&n=sahaqj52da2cjt986&d=n&v=0&b=1&a=1hp1s2d3c4d]266|200[/hv] How should we continue bidding on this board? We play SAYC-like system, RKCB 0314 (if needed). 3♣ bid shows better than minimum hand (we bid minimum competitive hand via Good-Bad 2NT). Please help, which bid by South is the best to investigate slam?

[hv=pc=n&w=sk85haq7d98c76543&d=e&v=e&b=6&a=1n3d?]133|200[/hv] IMPs What is your bid here? Assume standard methods, i.e. 1NT is 15-17, new suit is forcing, and double is negative.

I bid 2♥. No need for jumping to 3♥, because it's forcing.

Of course, but keep on your mind that you can't simply bid 3NT... just write down bidding sequence that leads to 3NT!

[hv=pc=n&s=s7532hkt9dk96caq6&n=saha765da87cjt543&d=n&v=0&b=1&a=1c1s?]266|200[/hv] Assuming standard methods, SAYC or BridgeWorld standard (it doesn't really matter which one), what is your bid with South hand?

That means that both 2♣ and 2♦ bids are artificial. 2♣ forces 2♦, which you can pass to play there or you can bid your invitational hand naturally. 2♦ is GF relay, asking for more information, pretty much like ordinary checkback, but is always GF.

2♣: majors 2♦: mini multi (weak two in one major) 2♥: ♥+m 2♠: ♠+m 2NT: minors all legal, no brown stickers :)

OK, then I'll post direct links: http://www.ecatsbridge.com/documents/files/ConventionCards/2010Ostend-european/OpenTeams/germany/piekarek-smirnov.pdf http://www.ecatsbridge.com/documents/files/ConventionCards/2008MindSportGamesBeijing/U26/Poland/Nowo-Wian.pdf

It's look more like standard, except that 1♣ is forcing, and can also be strong club. I attached two convention cards, so you can take a look on this methods. Nowosadzki-Wiankowski.pdf piekarek-smirnov.pdf

Last year on European Universities Championship I saw one Polish pair play 1♣ as 12-14NT, 11+ with ♣ or 18+ any, freeing 2♣ opening for some other hands (i.e. both majors, preemptive). How did they manage to do this, I don't know, and if someone know, I'd like him/her to share that wisdom with us. Also, studying WJ2005 I noticed there's no way to bid 18+ one-suited ♦ hand after 1♣ opening and 1♦ response.

I'd say it doesn't have to show real diamonds, just 4 spades, and can be balanced, because 1nt rebid is 12-13 in that case, and you may miss 2♠ contract. On the other hand, in my own Precision where we play 1NT=12-14, i'd play that sequence shows real diamonds, unbalanced hand, because 1NT rebid would show 15-16 BAL, and partner, who responded to opening almost for sure has invitational hand with 8+ points (else passes), so we can find spades using some kind of checkback sequence.

I'd like to know if following conventional openings are classified as brown-sticker conventions: 2 Diamonds opening that is either weak two in Hearts OR one-suited semiforcing in Diamonds simillary, 2 Hearts opening that is either weak two in Spades OR one-suited semiforcing in Hearts. Thanks in advance!
