I have removed the post date from the permalink urls. This is a rather easy operation in WordPress, but I also had to assure that all the old links are redirected to the new permalinks.
I think it works fine, but I still have to adapt all the internal used links in order to prevent unnecessary redirecting.
The third rank defense is the most important defense in the king and rook versus king, rook and pawn endgame. A lot of people refer to it as the Philidor position, but this name is also used for some other endgame positions.
There is already a lot of information about this position available on the internet, for example in the Philidor position on Wikipedia and I will limit this post to some additional information which probably helps to really understand this position.
First of all it is important to understand that the weaker side strives to capture the pawn or to exchange the rooks while being in a position that the pawn can be stopped. Therefor it is needed to be familiar with the single pawn endgame and the key squares. However the most important part of this endgame is creating a possibility to start a never ending king hunt by the defending rook which also results in a draw.
The third (or sixth) rank defense can be summarized as:
- The black rook is keeping the white king away from the sixth rank.
- As soon as the pawn moves to the sixth rank the defending rook has to be moved back
- starting a kind of king hunt with distant checks

The game below is a classical game between Dr. Thomas Bowdler and Henry Seymour Conway that can be found in the IJ105 database. The reason it became famous was because of Bowdler’s two rook sacrifice, but I’ll show it here for another reason: if you have a material advantage you have to use this material.

4.Qe2 d6 5.f4 A little bit to aggressive 5...exf4 6.Bxf4?! Qb6 7.Qf3? This can be considered as a blunder, but this game has become famous because of the two rook sacrifice, probably the first recorded one 7...Qxb2 8.Bxf7+ Kd7 9.Ne2 Qxa1 capturing the first rook 10.Kd2 Bb4+
( 10… Qf6! looks more promising )
11.Nbc3 sacrificing the second rook 11...Bxc3+ 12.Nxc3 Qxh1 13.Qg4+ Kc7 14.Qxg7 Nd7 15.Qg3 b6 16.Nb5+ -+ cxb5 =
( If you are captured your opponent’s rooks you have to use your own rooks, for example by 16...Kb8 17.Bxg8 Qf1 18.Bxd6+ Kb7 19.Be7 Rxg8 )
( 19… Nc5 )

Halosar_Trap |
( The main line of the BDG continues with 5.Nxf3 Bg4 6.h3 but this time we are going for the Halosar Trap )
5… Qxd4
( 5… c6 is played almost as often )
7.O-O-O Bg4?! Black falls into the trap. Most people do as it looks such a nice combination. 8.Nb5 Na6
