+<h2>When to perform checks</h2>
+
+<p>
+  For a Game Master, knowing when to call for a Check and when not to do so is a
+  Skill that develops over time through trial and error.
+</p>
+<p>The following guidelines can be of help:</p>
+
+<ul>
+  <li>
+    The Player Characters are heroes. Unless there’s a capable opposition or
+    immediate threat, a Player Character's actions should simply succeed.
+    Finding the tavern requires no roll — getting there without being noticed by
+    the local bandit gang, on the other hand, will take some effort.
+  </li>
+  <li>
+    Context and circumstances. The same action might require a Check depending
+    on when and where it takes place. Swimming in a calm river doesn’t require a
+    Check, while doing the same during a flood is extremely dangerous and would
+    require a Check.
+  </li>
+
+  <li>
+    Relevant background. If a character’s Traits or general background are
+    enough for them to succeed, the Game Master should simply allow it. For
+    instance, an aristocrat will have little to no trouble securing an
+    invitation for a court ball.
+  </li>
+
+  <li>
+    Impossible actions. Some actions simply cannot succeed, but you have to be
+    open to the Players’ creativity! You can’t jump from Earth to the Moon, but
+    you can build a magical ship to get there. You just need to remember that
+    nothing comes for free, and build interesting situations around the Players’
+    ideas.
+  </li>
+
+  <li>
+    Relevant failure. Failing a Check means the situation gets worse. If failure
+    has no relevant impact on the situation, the Game Master should simply
+    describe the outcome of the action and skip the Check. The same is true when
+    a character isn’t acting under pressure: their actions may require time, but
+    they will no doubt achieve their goal.
+  </li>
+
+  <li>
+    Stick to the rules. If the rules ask for a Check — or if they don’t —
+    there’s probably a good reason. Think twice before doing the opposite, and
+    only do so if everyone at the table is okay with it.
+  </li>
+</ul>
