My reference to square on was a common mistake shown on youtube videos. I have every confidence that Tommo has taught you well. Having entered triangularly..it is the attacker who is caused to spin circle or spiral around the aikidoka NOT THE OPPOSITE as is often seen. This puts the lie to the often large circular motions made by the aikidoka. The circles may be seen in the attacker's ukemi BUT the aikidoka moves triangularly. regards koyo shinkei As you say..NEVER attempt to throw or pin someone who has not been unbalanced properly first..hence the importance of the study of kuzushi.As for those who "make up" their own sword techniques...not only foolish but bloody dangerous. Below the triangle is in the aikidoka the circle is in the attacker (ukemi) and the technique is completed "square" meaning balanced.
