YUCK to Gerber, but ty for your answers; it really helped me understand. But I do find very strange what Ken says " 4C as a jump made directly after a natural NT bid". Rebid of 2N is often forced, as was in this deal, there might be nothing natural about it.

So, nag to both, and tip to running mentors, how about give a session on when we ought ask for aces? so many seem not have that figured.
The 2NT re-bid was natural. After 1
- 2D opener is forced to bid, that's true, and he should make a natural bid. With 5=3=2=3 shape and a 13 count, 2NT is very natural. It suggests a reasonably balanced hand and 12-14 points (or, on occasion, 18+, but responder assumes 12-14 until he hears differently). Besides being natural, it is informative. Opener will to always have exactly that shape but he will have approximately that shape. This allows responder to have a reasonable idea of where the hand should be played. With long diamonds and good values he might well think that there are 12 ricks as long as the defenders do not take the first two. Indeed this is correct unless there are four diamonds on his left.
This does not necessarily mean that Gerber is the best choice, just as RKC is not always the correct choice after, say, 1
- 2NT (Jacoby). When holding a void, Gerber is apt to be the wrong choice, just as RKC would be the wrong choice for opener after 1
- 2NT. So Gerber is a bad choice here.
I don''t share the frequently expressed disdain for Gerber. Used correctly, I have found it useful. Don't use 4NT RKC with a void, don't use 4
Gerber with a void, that's a good start. But with sensible use, it's useful.
What do you have in mind when you say that the 2NT re-bid is not, or might not be, natural? It's not strong, but it's natural.
Here is a starter rule for when not to ask for aces: If the answer that you get will not allow you to decide where to place the contract, then look around to see if maybe something else will. As mentioned, in the case at hand I would like to start a cue bidding sequence with the idea that if partner can cue hearts, I will bid 6
. If he cannot cue bid hearts, I will bid 5
. It's not that I will be certain of just how many tricks I can take, but I can control spades by ruffing, I cannot control hearts, so I am interested in whether partner can control hearts.
Note that as long as you are playing in
, you can still make 6
even though you will, very unluckily, be losing to the
J. There is no way you can find out exactly what partner has, and there is no way you can find out that
are splitting 4-0 iwith the wrong hand holding the length, but you can learn that partner has the
control, after which 6
is apt to have a play. That's all you usually get to know, that a contract should have a reasonable play.
