 *Sometimes, there may be multiple different ways to interpret a hand's blocks (e.g. 5568 can be seen as 556 + isolated 8, or 55 + 68).
-block theory is always better in isolation. But, when considering opponents' actions, keeping 6 blocks can be more flexible. If somebody calls a [[kan]] on 4-pin while you have 23-pin, the 23-pin becomes much weaker, so you can discard it and be better off than if you just had 5 blocks.
+In isolation, 5 block theory is ''always'' best. But, when considering opponents' actions, keeping 6 blocks can be more flexible. If somebody calls a [[kan]] on 4-pin while you have 23-pin, the 23-pin becomes much weaker, so you can discard it and be better off than if you just had 5 blocks.
 When discarding the 6th block, discard the weakest block you have (the one that improves tile acceptance the least). For example, if deciding between a penchan and ryanmen, discard the penchan. If you have two blocks of 23-man + 56-man, they have "duplicate acceptance" on the 4-man, so discarding one of those only leads to a loss of 4 tiles of acceptance.
