Valuable concepts that I wouldn't have figured out myself, thanks.

very interesting video but partly artificial position 

what are the real chances of this happening in a game????

The Bishop can not take the rook because it would be STALEMATE. That is good for the player with only the rook.

@BlessedStar

1.Rh8+ Kg6

2.Rh6+ Kf5

3.Rxa6 Stalemate 1/2-1/2

See the first few comments.

the other guy could win the rook

Simple and effective defensive techniques. Thanks Josh!

nice.. but  Rg6 is a blunder!!

good defence..

ok, thanks.

because it would be stalemate!

I'm a little lost, why did'nt the bishop take his rook?

Nice video.

I found this lecture to be a bit frustrating.  The ideas are not organized very well.  I can understand keeping the king close to the center for as long as possible, and once the king is forced to move toward an edge, to align the rook with the king with one square separating them.  However, there is no mention of an organized and general approach of achieving this position.  After that, the discussion was too specific to the moves made by the GM's opponent.  I would appreciate a more general blueprint in these how-to type lectures.

can you make the offence free next?

thanks royalflush.  I indeed overlooked the stalemate (which I often do).  Thanks for pointing that out!

awsome cool first page

Great comment hellfire and a point that should have been addressed by Mr. Friedel. You have calculated one move short in that Black has the amazing drawing maneuvre 1...Ra6 2. Rh8+ Kg6 3. Rh6+ Kf5! 4. Rxa6 Stalemate
