   I remenber I have played 3check with my friend last week .I remenber it's a biltz and he finally won the game . But I still can't believe he win me.So, we played more game and get same result: I can't beat a beginner in 3check.
    This thing passed easily .But one thing get stucked in my head:Is that chess variant can improve one's chess skills and rating?This variant changed the basic rules and chessboard and pieces and make chess have more fun.But will this variants destroy the essence and charm of chess?
  (P.S:I'm not good at English ,so it may be a terrible article.Forgive me please.)

Play variants for fun or sport. 

But variants will not help your chess.

EXACTLY----chess Variants require an entirely different skill set to succeed...they will actually *hinder* normal chess skilks/rating...
