Playing Tip #1

1 - Count your losers. Decide which ones can be disposed of or turned into winners (by trumping, by finessing or by discarding them on a side suit). 
2 - If your plan calls for trumping one or more of your losers in the short-trump hand (usually dummy), do that before you lead trumps - even if you have to give up tricks to set up the trumping position. 
3 - Next, lead out your trumps, counting as the opponents follow to each trick. (This will usually be your best approach if you have good honour strength and/or length in one or more of the outside suits.) 
4 - Attack your longest side suit. Give up your losers early. 
5 - Cash honours in your short suits.
