I am learning brioche at the moment. There are two methods, one is with yarn-overs and the other is without yarn overs but putting the needle in the stitches of the last row. Maybe that is the difference with 'tuck'?
The method with the yarn-overs seems neater (in my beholder's eyes).
I'm familiar with the yo method from playing around with brioche in two colors but the other I don't know anything about and my brain can't make any sense of the description. Could you please help out a brain dead knitter and maybe post a link if it's not a bother? I can do some searching and see what I can find.
I got really frustrated with brioche not because it's too hard but because I kept making what I consider stupid mistakes. Those 4 stitch decreases are hard to fix when I do something wrong and I kept splitting the yarn.
Back in 2008, Elise Duvcote published "Knit one Below" on this technique. Not quite the same as brioche , the right side looks a bit the same but the wrong side looks different. The technique is similar to Elizabeth Zimmerman's fisherman's rib.
