The thing is that every board is different so there isn ' t a set strategy . Something ' s that are common for most games is that you want to try to work towards longest road or largest army . Which one you choose is most likely based on what materials you are on . Buy development cards of it is your turn and you are at say 6 cards . This could save you from a bad discard . Only ever trade with someone if it DIRECTLY helps you . If it won ' t get you a point or something you need road development card ect . Dont do it because your just helping your enemy . In games that have very low amounts are a certain resource you should think about getting a 21 port . Last night we had a game where wheat was 12 , 2 , 11 , 3 so having a port helped get this ever so needed wheat . On that note ports are every good even 31 . Its good practice to try and remember what was rolled and who has what resources . This comes in handy if you have a monopoly or if you roll a 7 . If you know what the person has , and what they need you can harm them a lot more with the knight . Never get too far ahead in the game . This will cause you to be a main target for knights and no one will trade with you . The best way to not be targeted is to work toward longestlargest but try and take it on a turn when you are getting 12 other points . A lot of games Finish with someone going from 67 points to 10 . I have to go to work now I hope that helped a little .
