Rc5 is really nice, but you know, white could also just play 1 e4 :)
After 1 Rc5, can't black just try 1...Rd5? Then 2 Rxd5 is met by 2...Qxd5+, when at least black has a little more time to do something about white's threat (such as making room for his king to escape).
I reached an interesting position today in live chess and decided to share it.
