{Queen vs Rook ending. Black wants a draw, White a win. But how to win this
position. Black strategy is to make a fortress.Observe the Rook prisoning
the King, not letting him cross over forward.Observe the Black pawn is on the
6th rank. It is unique feature of this specific Queen vs Rook and pawn endgame
position. Dvortsky has a discussion about it in his manual.In these kind of
positions, make moves that limit your opponent's choices. It is not wise to
make checks, for check sake.Here White's last move was 59. Qa6-c8.Black's
rook's move on the rank are limited Ra5?? 2. Qc7 Rb5?? 2. Qd7Rc5? 2.
QxR..Rd5 has to be checked..Re5 also..Rf5? 2. Qxf5! wins! ..Rg5?
2.Kxg5Rook moves on the file...Rh8? 2. QxR..Rh7? 2.Qd7 Kg8 3. Qe8+ Kg7 4.
Qe7 Kh8 5. Qf8 Mate..Rh6 2. Qd7+ Kf6 3. Qe8 with the threat of 4. Qf8 Rh5
5.Qf8+ Ke6 White has succeeded in separating the king from his pawn, so the
fortress is no longer holding. Qg7 and the g6 pawn falls.} 1... Kg7 2. Qe6
{The merit of Qe6 upon the e8, is that here the Queen still keeps an eye on f5
and keeping the strategy of taking possible moves from Black.} 2... Rh7
{Desperately trying to keep the pieces close to the king. Fortress strategy.
note that 2..Kh7 3. Qf6! Now note that Black can only move his Rook since the
king has to stay on his square to protect the king} 3. Qe7+ Kg8 {..Kh6 62.
