Matchpoints (MP)	IMPs
Contract type	NT first, majors next, minors last	All types equal, seek the most comfortable makeable contract
Partscores	Fiercely fought over	Battles continue, but are toned down
Games/slams	Bid moderately	Aggressively bid, especially when vulnerable
Pre-emptive actions	A widely used tactic	Emphasised. Can create large swings
Sacrificing	Aggressively pursued	Need a clear-cut save; absolutely no phantom saves
Safety Plays	Infrequent as overtricks are so important	Frequent, as ensuring the contract is all important
Penalties	Usually lots of leeway as only one board is involved if you misguess	Bidding is sounder (especially red vs white) to avoid large penalties
Distributional hands	Normal treatment	Insure against big swings--bid one more in competitive auctions
Doubling	Extensive, especially at partscore levels	More limited; needs to be clearly your hand, a trump stack or misfit
Use of undiscussed conventions	Can happen infrequently	Avoid like the plague!
