I'm fairly new to the came, and this came up in one of my games. I was presented with a a Reckless Duel. I did not focus, and instead played Know No Fear. My opponent tried to deny me this use since it was past targeting. The way english normally reads, is that this reaction is to be taken anytime after my guy is targeted, but before the effects resolve. However, I have found in the online rules that "After targeting" is essentially "before anything else happens." (per: http://rules.l5r.com/EE_Timing)
Based on the wording of Reckless Duel, and Know No Fear. At what point do I actually have the opportunity to play Know No Fear against Reckless Duel? Can I even attempt to win the duel before I played Know No Fear? (This was not what happened in the particular example above, just curious.)
