Perhaps the problem isn't in the commitment of the attack (agreed - very rare), but the commitment and confidence in your response.
When you find those of us who do know how to strike, don't critique or criticize us. Stay open and train hard.
I agree with statement "commitment and confidence in your response". However it is not enough to say 'train hard". To develop such confidence when facing minimum commitment from attacker, we should be able to have a very precise set of drills. I've never seen such systematical approach in any aikido training. That's the reason for my question.
If ultimate goal of practice is to be able to respond spontaneously to any situational scenario, and we constantly train only one case - strongly committed attack - we will never reach such goal even with very hard training.
