Board 3, 25:30 On this board, you emphatically state that dec should choose the H suit to set up and not the D. Why? Thanks very much in advance, Catherine
Because of the AK of hearts, you need to ruff fewer hearts to make them good than diamonds. If the diamonds break 4-2 you will need to ruff 3 of them which may be tough to handle.
on Board 2 if the bidding goes: (4♥) p (p) dbl (p) 4nt What would 4nt be saying?
Its pick a minor. When we double 4♥ we are often in a bind and dont have perfect takeout double shape. So when responder wants to bid 5 of a minor. EG. x xxx Kxxx Jxxxx they would bid 4NT so they dont end up in a 5-2 club fit instead of a 5-4 diamond fit. (it can and has happened). In general those 4NT bids mean two places to play. After 4S X P 4N could be any two suits... In modern day, the new thing is to play (4♠) X (P) 5♥ = slam try in hearts, and with a bad hand you go through 4NT and then bid 5♥ We have just added that: (4♥) X (P) 5♦ = slam try in diamonds along the same idea. Our teammates had a disaster on this auction because they didn't have this agreement in the 5th set of the match we lost.
So no way to signoff in 4nt by North? As you said in the video 4♥ is a destructive bid.
It is pretty rare that you would want to bid 4NT to play in a spot like this. You have the option of passing them in 4M X, usually when you have their suit well stopped you are happy with that route. I don't consider "not being able to bid 4NT to play" as a major reason why 4H openings are effective.
Board 3... I decided to take the low road as North and not force to game immediately. It seemed like it could be one of those misfit hands that can't make anything. Over my 1♠ response my partner judged well to show a medium 16-18 raise to 3♠. Now I considered bidding 3NT serious to catch up my values, but remembered some rule about it not applying before a game force is established. Do I have that right? Should 3NT be an offer to play, or something else?
When you say "not force to game immediately", I hope you realize that you cannot game force later. You are choosing to treat this hand as an invite. The idea is that when you bid 1♠ and then make a game forcing bid with a second suit that you promise 5 spades. EG. 1♥-1♠-2♥-3♦... this promises 5 spades. 1♥-1♠-3♠ is not a serious 3NT spot, nor is it needed. Partner has shown a very well defined range of 16-18, so when we make a slam try they are going to be evaluating where they are in that range. I play a nice tool with my partners 1x-1Y 3Y- 3Y+1 asks for shortness over which we answer None, Low, Hi in the first 3 steps. Identifying opener's shortness (and hand type) is really useful in this spot when you are looking for slam.
are you saying 1♣ 1♥ 3♥ 3♠ 3♠ is asking for shortness? think I am misreading this, 3♠ would be a control?
You aren't misreading it. Thats what I play with all of my expert partners, first step says "do you have shortness?" So 3♠ in that auction would say do you have shortness and opener's answer is 3N = no, 4♣ = shord diamonds, 4♦ = short spades
Hi Gavin, question on 6--I had the west hand and started as you said, heart transfer, 2S, passed to me. I bid 3D and partner misunderstood thinking I had more values, which is fine--but later I kicked myself for not using the leb. 2N relay to 3C and then bidding 3D to show the weak 5-5. So you're saying experts don't bid that way anymore, but just use x for 8+ and a natural bid for less? Thanks.
Lebensohl is only in one specific spot. We open (or overcall) 1NT, the opponents overcall in the direct seat, and its the respponder's turn. If you are applying lebensohl in other auctions you are totally on your own. Would this be a terrible place to play lebensohl? maybe not, but that would require a special agreement. So "experts don't bid this way anymore" isn't accurate, since experts never bid lebensohl in this spot. 2NT would just be 8-9 points. I will cover it next week in the lesson.
