Gib seems to not know his system too well: here is how he bid this hand[hv=d=e&v=n&s=sqh954dqt874ckq86]133|100|Scoring: IMP P-P-P-1NT P-2♠-P-2NT P-3♥[/hv] on the system notes, he should be bidding 3♠ to show a singleton ♠. I wonder why that happened. You can look at the hand on bridgebase. It is the 8th hand I played on April 20th. Bill (bill1157)
