Re: "Tricky" energy and the committed attack
imo, that is the difference between fighting and self defense. When a confrontation occurs and the, lets say nage, takes up a fighting stancem this tells the attacker that they have to be tricky in order to launch a successful attack. This is what leads to the feints, jabs, and fakes that you see in fighting. If nage takes up a relaxed stance, he may be very ready for the attack, but look very open. This is when bullies try to take the "death blow" that we aikidoka prefer. I dont think aikido was developed for fighting, but when it is used for self defense the evasions and techniques all make a lot of sense.
