Bidding explanations:
2♦ - Alerted - Standard Multi
2♠ - Not alerted - E-O do not have any agreement, so East thinks than they play Standard defense, and West thinks natural.
3♥ - South didn'at ask for 2♠ meaning till the end of the ouction (but see before in the AC)
3♠ - Support in ♠ (natural).
3NT - To play anything (Good!!!)
Before lead, South asks for the meaning of 2♠, and West says than she does play the sort, but like E-W has no agreement, she thinks it's natural.
Souths lead the ♥K, 9, 8 and A. South asks West why she didn't correct to 4♠. She says than if pd wants tio play 3NT, she has a good hand to play there.
East plays ♥2, Q, 10, 6.
South then plays the ♥7!!!!!!, and East claims 9 tricks. At this moment, South asks for TD, climing the misinformation from North, and explaying than the bad explanation afected his defense!!!!!!!!.
TD ruled than there was not misinformation because E-W has no agreement, so result stands.
N-S appeal the TD rule based in to points:
1- East must correct West's explanation before South leads.
2- East missdefense based on misinformation.
During the AC hearing South and North say than they do not ask for the meaning of 2♠ at any time.
Some more information: both pairs are normal good players. East-West are ocasional partnership, and North and South are good players, but not top players, and regular partenership. 2♦ Multi is not a usual convention in this tournament.
