Reading pre-attack cues isn't hard....you just have to look for it AND believe what you're seeing!

 

Dude telegraphed this "attack" from a mile away. Luckily the big guy saw it coming and luckily he was effective in blunting it. I am however seeing more and more stories of people seeing an attacker, failing to make note of cues and then being savagely beaten. BELIEVE WHAT YOUR EYES ARE TELLING YOU! Then use the training that you've acquired (if you don't have it then get it...if you have it then practice it!) to defend yourself! If you get really good then you can evade the attack before the distance is closed.
