agree

Not calculating i would like 4S/3Nt Getting this to 50%... Trumps 3-2 plus finesse for the missing queen= 34%. Or 4-1 i need 3-3 ♦s plus finesse queen trump=4% or 4-1 west plus 4-2 ♦ west and finesse trump= not a lot. On top single queen and double honours in Ds= few %. Al in all: is difficult to get 50%

2♦ showing an opnening hand with six ♦s. (not a strong opening hand though)

1♥-2NT 3♠-3NT (shows singleton, 6-7 loosers), Where? 4♣-4NT (club single) and 1430 5♦-5♥ (0/3 aces but could be 0) 5NT-6♥ (3 aces no outside kings but xtra trumps= Q trump) since i can't locate the double Diamond i can't bid a grand

I prefer (no 2/1): Splinter with 9-11 (12 Bad) with more use 2NT. It's important to limit splinter strength or it's to difficult in further biding. Direct splinter=Void Indirect=single 1H-3S=indirect, 3NT asks. (Void with spades=3NT) 1H-3NT/4m=void 1S-3NT=indirect, 4C asks. 1S-4x=void

This is IMO a good idea, which i've seen described b4. Can still be combined with trial style bids at 3 level. We don't raise to 2M with balanced 3 card trump do we? Eg. a good raise to 2H is x Kxx KQxx Exxxx

Where do you see 8 tricks??? :) I normally do this by taking 13 and subtracting the loosers ;-) I agree this is not a clearcut 2C opener. I do it since with this hand i don't want P to pass, my opening bid. only opening 2C would provide any chance of reaching 6♠ IMO

Biding: 2♣ (8½ trick, i don't want p to pass)-2♦(0-1 controls) 2♥-2NT (5+ spades, 2♠ would be negative relay) 3♦ (5-4)-3♠ (6 spades) 4♠ (missing too many controls)-6♠/pass(practical bid since p will never guess our hand)

DBL just like one it's done when playing bridge. The pause will already make me consider calling director

I have played both natural responses (2D negative) and control and definately like control responses the most. Two things which control responses do good 1.U can almost at once know if the hands are game or slam potential. After a possible preempt it's easy to know if u won't to double them or do your own game/slam. 2. Also playing control responses cut down on what u have to remember (VERY IMPORTANT IMO) Playing control responses it's very important that responder has a relay bid avaible after opener shows a suit to show biding space. Also only the strong hand should bid any kind of RKC/Blackwood. I've had no difficulty with the 2NT bid (showing 4 controls), for once it's very rare and secondly when a 4 control hand is opposite a correct 2C hand it's not important who get's to be declarer. Typical 2C 2-suiter: EKDxx Ex Kxxx Ex Not too much trouble if P bids 2NT...

Ok i'm looking the wrong place since it's not in the ZarPointsBOOK. Pls give me a link. P

I don't mind biding NT with five card majors. With weak double sometimes open 1M. A good 17 gets upgraded to 18. Mostly i don't need the puppet stayman, reg. stayman works out ok. All those fancy bids are great, but well mostly u don't really need them... To show 5-4 invitational hand as responder i use: Transfer then 2S when 5H+4S. 2C, then 2S after 2D(neg) to show 5S+4H. (when i have GF i transfer to spades and rebid Hs) The advantage is that it's easy and logical to remember. All rebids by responder are natural including minors.

Would bid 3H any day. That hand is ok opener and becomes great after DBL. I agree with justin that gamescore would be good enough. Would never find 6C

In brief it's more attractive to open 2C when one of the suits is a major, less with only the minors. I would recommend you read this article: Link

Ok Mr jokster answer this: How much better a priori is it to play 3NT than 4M with a 5-3 fit What are the percentages? No feelings involved ;-)
