Matchpoints, ACBL robot individual

The North hand was something of a disappointment when revealed. If it had been anything close to what the notes documented (given confirmation via grand slam force that North held ♦KQ), the grand should have been near lay-down. And, yes, I could have settled for the small slam and earned a 90% score in this instance, but if North really did have a very good hand, 6♦ would likely have been a well-below-average score.

North is forced into its substandard 3♥ by East's impertinent crowding of the auction. Opponents tend to do that. Which is one of many reasons I think bidding ♦s before ♥s with a hand as weak as North's is a losing proposition. Bidding 1♥ gets you to 3NT on this hand, which was worth 80% of the matchpoints. But if, as I expect, theory continues to prevail over pragmatism, the notes should be revised to reflect that North can have a 9-count for its 3♥ bid when the bidding gets jammed like this.

Not that it's relevant on this auction, but I've seen this happen a lot... if 3♦ shows 4+ diamonds, doesn't it also show 5+ clubs, since GIB's system is to open 1♦ with 4/4 minors?

Thanks for reporting.

Both N and S calls were corrected in next v33.

When opener gives fit to partner's diamonds will show 5+♣ 4+♦ as here.

New 3♦ would have the meaning -> -- 5+ ♣; 4+ ♦; 15-18 total points

On the other side, 3♥ ( or the unbid major ) would show -> 5+ ♦; 4+ ♥; 10+ total points
