Do you want to know the answer? First, ask your fellow aikidokas, their teachers, or even the most respected akido shihans today, the fallowed question. The question is: "Are they able, for sure, to avoid every first attack of any boxer, or just anyone?" O-Sensei was able to do it, and that is the essence of His art. Think about it and don't look for the answer on this forum even if you were joking.
