1 0.3 ROOK AND PAWN AGAINST ROO K AND PAWN

Although these endings are usually drawn, even in such simple positions there are many subtleties, and so some theoretical positions and typical methods of play are best known. In the majority of cases the game trans­

poses into either a rook and pawn vs. rook, or a rook vs. pawn ending.

We have examined the transition to rook and pawn vs. rook and rook vs.

pawn endings. Besides, some interesting tactical and strategic ideas occur in rook and pawn vs. rook and pawn endings. One of them is demonstra ted in this famous study by Emanuel Lasker.
