Even Roman Blackwood convention has several variations, revolving around 5 ♥ and 5 ♠ responses. In all variants, they denote 2 aces. One variation is that 5 ♠ shows extra values, while 5 ♥ does not. In other variations, responses 5 ♥ - 5NT denote specific combinations of aces (same color, same rank, or "mixed").
Responses are given in the style of Roman Key Card Blackwood and may be based on a key-suit king instead of one of the aces normally shown. Key suits include: [5] the trump suit, any genuine side suit bid and supported, or; any suit bid by a player whose partner's first bid was in notrump.
A mnemonic for a variant response structure to the Roman Key Card Blackwood convention. It represents "1 or 4" and "3 or 0", meaning that the lowest step response (5 ♣) to the 4NT key card asking bid shows responder has one or four keycards and the next step (5 ♦) shows three or zero. 1RF One round force. 2-under preempts
Socratic questioning (or Socratic maieutics) [1] is an educational method named after Socrates that focuses on discovering answers by asking questions of students. According to Plato, Socrates believed that "the disciplined practice of thoughtful questioning enables the scholar/student to examine ideas and be able to determine the validity of those ideas". [2]
An example would be if the students in the school had numbers attached to their names ranging from 0001 to 1000, and we chose a random starting point, e.g. 0533, and then picked every 10th name thereafter to give us our sample of 100 (starting over with 0003 after reaching 0993).
The Grand Slam Force is a bidding convention in contract bridge that was developed by Ely Culbertson in 1936. [1] It is intended to be used in cases where the combined hands of a partnership are so strong that a slam (winning at least 12 tricks) is a near-certainty and a grand slam (winning all 13 tricks) is a possibility.
3 ♦ or higher, etc. on up the line. With ace-showing responses, the responder bids the suit of the Ace, 2NT with two or more kings, and 2 ♦ with a king or less. With (unlikely) 2 aces, the responder bids 3 ♥. As a corollary, subsequent Blackwood by the opener asks for kings rather than aces.
