After a 1 level opener and a 1 level response, if opener rebids 1NT he is showing a balanced hand with minimal opening HCP count. If opener jumps to 2 NT after a 1 level response of course he/she is showing a stronger hand. BUT After a 1 level opener and a 2 level non-jump response (1S-P-2C-P does opener's rebid of 2NT show a minimal opener or the stronger hand? 2NT) ALSO After a 1 level opener and a 2 level overcall OR a 1 level opener with a 1 level response response followed by a 2 level overcall(1H-P-P-2C OR (1C-P-1H-2D does a 2NT rebid show a minimal hand or the stronger one? 2NT) 2NT) Any advice would be helpful.
