I had a bidding accident in a recent bidding practice and wanted some opinions. What do you think should the following auctions mean? 1C - 1S; 1NT - 2H; 2S 1C - 1S; 1NT - 2H; 3S 1C - 1S; 1NT - 2H; 4S 1C - 1S; 1NT - 2H; 2NT - 3H; 3S 1C - 1S; 1NT - 2H; 2NT - 3H; 4S 1C is artificial and forcing 1S is 4+ with 8+ hcp 1NT is GF (guarantee 16+ hcp) asking for further description but not part of a relay structure 2H is natural and deny a minimum (show at least 10 hcp) 2NT does not promise or deny any specific shape Over the 1S response opener had available to him 2NT as 4 card GF raise with shortness, 3S as 4 card GF raise without shortness. I believe those are all the relevant agreements but feel free to ask Thank you for your help
