Eyes on! 

 Jack, I just crave attention! Please please, I know you are busy, but please please, pretty please, just reply to me!! A simple "Yo" from you would make my day and give my life meaning (well, if not "meaning", at least I would smile).

"Check mate king two, this is white rook." 

 Hello self, it's "Check mate TO king two, this is White rook" (from Independence Day). 

 Just saw your "Yo" to me! That's really fun and cool! Thank you!
