Both rooks (B) on the 7th, one on the 8th (W) , and the other somewhere else (W).


This situation comes of up from time to time in middle games and endgame.  Here's a sample diagram:

Black has an easy draw in this specific set up.  But I'm looking for more general information.  Don't assume pieces are in this exact position.  Are there guidelines for such a setup.  I know I can try to

  • Set up a pin check to pick off a rook on the back rank
  • Find a way exchange his rook
  • Skewer king in front of his rook by arranging your rooks on the back rank

Does not seem like a draw with White to move. Rb3 defends the first of all the future perpetual checks.


Remember to state which side to move.


There are no specific guidelines to follow, but the perpetual often happens when the defending king's (the side who is on the receiving end of the perpetual check and cannot evade the repetitions) escape path (in this case, to d1) is blocked by a friendly piece or guarded by an enemy piece.


Sometimes you can use some dirty tricks to win the game. If, as an example, the piece occupying d1 is instead a Black queen, then Black to move nets the exchange after 1...Rgb2+ 2. Kc1 Ra1+ 3. Kxb2 Rxd1.
