Knowing a Trap

All the markings of danger read, actions upon it make you dead; back off from it by prudence's stead. King cobra fangs and crueler things, cautions wary and messages brings; attacks come like a siren sings. A ship captain must know to moor, when typhoon waves strike the shore; a trap is set as in classical lore. Knaves and scholars face equal risk, the silent sudden attack is brisk; the unforeseen trap is swift as a whisk. A man, a warrior makes plans in haste, he has no time for justice to waste; but wisdom tells the poison pill is laced.
