King Vs. King & rook

Here is a endgame puzzle for you to solve.

I hope you can solve it

HINT: His king on e5 is right in the center, perfect for a king-rook checkmate

Rf6

Excellent job, everyone. Especially you NM JMB2010

U were joking, right?

No, it's Rf5 checkmate. 3 checks mate! (Assuming white has already given 2).

yes, i was

There is no win for either side here, this is a dead draw. No matter where the rook moves, black's king will capture it.

The longest mate with K+R vs. K is 16 moves. Your position is a mate in 12, if White can find the one correct first move.

Can you find one of the positions where Black can hold out for 16 moves?

I'm guessing White King a8, White Rook f3, Black King e4

Correct. In fact with those king locations, there are 28 squares for the rook to have a mate in 16. All other legal rook locations give a mate in 15.
