I was amazed to find that out of 45 times this hand was played in an ACBL Robot MP tourney today, I was the only one to make the initial 2H response.

I reached the normal contract despite the fact that, after GIB's 3NT rebid, I wanted to bid 4S to show my shortness there with a D fit. The description did not indicate that meaning, so I bid what I thought would make. A favorable opening lead later I took all the tricks for a shared top.
All other times I have made the SJS with a fit for partner's suit I was able to show shortness in the way the treatment is designed.

The point? Use the system. This hand is a clear-cut SJS so forget about "wasting a round of space" and make the bid that allows you to describe your hand most accurately. And newer players, check the meaning of bids before you make them. No fewer than 10 players languished in a part score after bidding 1H and making a non-forcing ♦ bid the next round.

Bizarre 3nt rebid. What prevents it from 2nt?

Thanks for reporting.

Previously it wasn't included in the sequences about similar intervention by opponents.


Now it's added.

So if South uses now new suit over NT replies would shows spliter.

Similar if North bid a suit and not NT.

The way I was taught to bid over strong jump shifts is make your normal bid (as if responder hadn't jumped) just one level higher. If you would jump then jump. So this is a clear 2N rebid. 3N would show 17-19 not a range so wide it is useless 11-17. 3N with that wide meaning is a slam killer.

So my old school of bidding would have went:

1♦-2♥-2N-3♦ (agreeing ♦ with lots of room for cuebidding to find 6♦)

I agree with both who questioned GIB's 3NT rebid. Too bad Georgi didn't address that part of it.

Since I don't play SJS with anyone, I forget often to play this with GIB.

Nothing terrible about that Steve but I have found it more effective to reserve your auction for 2542 shape and show the shortness when held.

I'm guessing that the way Steve was taught, like the way I was taught, was not Soloway Jump Shifts. If GIB is going to say that he plays Soloway Jump Shifts, then he should play Soloway Jump Shifts.

I don't know if either of these is a definitive text, but we shouldn't be making it up as we go along.

True enough, GIB should be consistent. As I said in the OP, every other time I have used a SJS with the suit + fit hand, I was able to show the shortness, described correctly. This may have been the first time an opponent interfered. Of course since I play in the human best hand tournaments, GIB virtually never has a hand good enough to make one itself, and if it did I would also have a big hand.
