Slam-seeking conventions Slam-seeking conventions Slam-seeking conventions are codified artificial bids used in the card game contract bridge. Bidding and making a small slam (12 tricks) or grand slam (13 tricks) yields high bonuses ranging from 500 to 1500 points. However, the risk is also high as failure to fulfill the slam contract also means failure to score the bonus points for a game (300-500). Conventions have been devised to maximise the opportunity for success whilst minimising the risk of failure. Contract bridge bidding systems are mainly "natural" (most bids have an obvious meaning) or "artificial" (many bids have a meaning unrelated to
Principle of fast arrival to game leave less room for slam investigation, they imply an absence of slam values and therefore discourage more bidding. In addition, on weaker (or limited) hands fast arrival has a pre-emptive effect on the opposition and minimizes the information they might otherwise exchange. Stated conversely as the principle of slow arrival, the approach leaves more bidding space for stronger hands to explore for slam or choose the optimum game contract. Principle of fast arrival In the game of contract bridge, the principle of fast arrival (also known as the principle of slow arrival) is a bidding treatment widely used
