Какая разница между "знать, как играть" и "уметь играть"?

[Neon_Iceberg]

When you say "знаю, как играть (делать, водить (driving) and other verbs) it means that you know how theoretically to do it. If you say "умею играть (делать etc)" - it means that you have had experince in it.

[Conner561863]

Could it be: "Ты не умеешь играть в эту игру" ?

[Shady_arc]

не умеешь играть is "cannot play" (due to the lack of skill).
