I have seen combinations of techniques done by my sensei, while he was demonstrating ikkyo to us. He said that these simple actions can lead to many different endings, (Its the beginners' class) and its essential to get the footwork and movement right.
He then performed something like (shomenuchi)ikkyo/kotegashi and some other techniques that looked impressive, but i do not know their names.
Another one looked like when sensei is finishing the ikkyo with uke's arm being almost in control, but bent, instead of straight like in an arm bar, then sensei reverses the direction and throws uke backwards. Sorry if my description sucks.
