Reoccurring bug in GIB bidding: after responding 1S to 1H, GIB will rebid 2S over opener's 2 of a minor with weak 6-card Spade suit instead of bidding 2H with 4-card support, i.e., a known nine card Heart fit. This has happened to me and my BBO friends several times. See an example in the attachment and in this link: http://online.bridgebase.com/myhands/fetchlin.php?id=2730665&when_played=1296328501 Jim Olson BBO: jdolson

Today while playing in an ACBL Robot Matchpoint Duplicate (Tournament #4292, GIB is W, N, and E), I had this auction - South(me) Dealer: 1♥ P 2♥ 2♠ 3♥ P P 3♠ P 4♠ All Pass At seven other tables, the human player sitting South also bid 3♥ over 2♠ but the auction continued differently??!?: 1♥ P 2♥ 2♠ 3♥ P P Dbl P 5♦ P P I have never seen this happen in an ACBL Robot Matchpoint duplicate; usually if the auction is the same up to GIB, GIB will ALWAYS make the same bid. In fact, I thought the ACBL Robot game was set up this way to make sure that the GIBs make the same bid on the same auction. Has anyone else seen this happen...? Regards, Jim Olson To check the Bridge Movies, go to 4-18-2010 Tournament #4292, Board 3 and compare No. 1-7 with No. 26, e.g. BOOKER1 with jdolson (Traveler 4292-1271597401-86585611). Note that when I practice with a human partner against two GIBs in the Main Bridge Club, it is routine to see GIB bid differently on the same auction when reviewing the Bridge Movie - but NOT in the ACBL Matchpoint Robot duplicate.
