you can start with normal mentality and see how it goes if you don't want to be exposed from the beggining. my plan b would be to play back with 3 dc and the forth defender replace him with mc. also another option is to play the diamond but instead of ml/mr use them as aml/amr. anyway don't be dissapointed from the first result. it happens. you must never play narrow diamond against ml/mr or aml/amr
