plz tell me about RK vs BK endgame. Is it a draw??

 

In majority of the cases, assuming there are only those four pieces on the board, the outcome is a draw with either side to play. In a minority of cases (some positions of which are shown below), the side having the rook wins (the side having the bishop can never win since it is not possible to come up with any series of legal moves to land a checkmate on the opposing king). These usually happen when either the bishop drops by a check-fork or the king is located near the perimeter squares of the board.

 

 

 

 

The first two diagrams are wins for the side having the rook. The third diagram is a draw with either side to move.

 

Also is interesting the following position.

Quite interesting ideas threatening mates with smaller threats of pin and skewer.

What's the right plan for Black in this very common kind of position.

 

If White's pawn were on a7 it would be an easy draw, but here White can try to get his/her king to a7. So how does Black counter this idea? And how would you assess the position? Cheers!

 

 

1...Ra5; 2...Re5; 3...Re6 draws because it keep the white king from penetrating black position.

Thank you. Is that the Vancura method?
