K+Q vs. K+R: One more key position to know

 A few months ago, I posted an article about queen vs. rook. I have one position to add to it. 



[Event "?"] [Site "?"] [Date "????.??.??"] [Round "?"] [White "New game"] [Black "?"] [Result "*"] [SetUp "1"] [FEN "8/8/8/8/1K6/8/rk6/3Q4 w - - 0 1"] [PlyCount "5"] {If it is Black to move, then it's zugzwang. If it is White's turn, then the best move is} 1. Qd5 $1 ({Not} 1. Qb3+ Ka1 2. Kc3 $4 Rc2+ $1 3. Kd3 Rd2+ $1) ( 1. Qd2+ Kb1 2. Qe1+ {hopes for} Kb2 3. Qd1 { zugzwang, but Black can avoid this with 2...Kc2}) 1... Kb1 2. Kb3 Rb2+ 3. Ka3 { and the rest is straightforward} *



Converting Q vs. R was critical to becoming the #1 endgame benchmark player on ChessTempo
