yfwd.K2.pass yfwdover K2 means that you bring your yarn forward of your needle (as if your going to purl) with yarn in this position knit two stitches you will see that the yarn looks as if it has made another stitch, after you have knitted the two stitches go an pick up the yarn that is over the needle (right hand needle) and pass this over the two stitches you have just knitted, then K2 and carry on with your pattern. I hope this was of some help.
