2. Rook and bishop versus rook endgame - Wikipedia

   en.wikipedia.org/wiki/Rook_and_bishop_versus...

   Being a five-piece endgame, the rook and bishop versus rook endgame has been fully analysed using computers. Endgame tablebases show that 40.1% of the legal positions with this material are theoretical wins, but that includes many unnatural positions that are unlikely to occur in games.

3. Rook and pawn versus rook endgame - Wikipedia

   en.wikipedia.org/wiki/Rook_and_pawn_versus_rook...

   A pawn is referred to by the file on which it stands: a rook pawn is on the a- or h-file, a knight pawn is on the b- or g-file, a bishop pawn is on the c- or f-file. A central pawn is a queen pawn or a king pawn, on the d- or e-file. When designating a position as a win or a draw, optimal play by both sides is assumed.

4. Wrong rook pawn - Wikipedia

   en.wikipedia.org/wiki/Wrong_rook_pawn

   In a king and pawn versus king endgame with a rook pawn, the defending king only has to get in front of the pawn to draw the game. In contrast, in the endgame with a bishop and the wrong rook pawn, getting the defending king in front of the pawn will not necessarily draw. In this position from Edmar Mednis, White wins if it is their move. 1 ...

5. Wrong bishop - Wikipedia

   en.wikipedia.org/wiki/Wrong_bishop

   A rook and a rook pawn always win against the wrong bishop, as in this position. The defender has the wrong bishop if it is the one on the same color as the pawn's promotion square. The winning procedure is to give up the pawn at the right time to get to a winning rook versus bishop endgame. If the bishop was on the other color, the defender ...

6. The exchange (chess) - Wikipedia

   en.wikipedia.org/wiki/The_exchange_(chess)

   The modern consensus is that the side with the two bishops need at least a pawn when facing rook and knight, even then the side with the two bishops is underdog. William Steinitz reckoned that often two bishops and two pawns are superior against rook and knight. A rook and bishop usually work better together than a rook and knight in the endgame.

7. Pawnless chess endgame - Wikipedia

   en.wikipedia.org/wiki/Pawnless_chess_endgame

   Rook and a bishop versus two knights: this is usually a win for the rook and bishop but it takes up to 223 moves. [61] The result of this endgame was unknown until computer analysis proved the forced win. Rook and a knight versus two knights: this is usually a draw, but there are some wins for the rook and knight that take up to 243 moves. [83]

8. Domination (chess) - Wikipedia

   en.wikipedia.org/wiki/Domination_(chess)

   The example here is a study by Henri Rinck first published in La Stratégie in 1920. It is White to play and win. Normally, Black would be able to sacrifice his rook for the white bishop, leaving a drawn position (sacrificing it for a knight would be no good, since it is possible to force mate with bishop and knight), but in this case it turns out that the rook is dominated, and its capture ...

9. Opposite-colored bishops endgame - Wikipedia

   en.wikipedia.org/wiki/Opposite-colored_bishops...

   If the pawns are on the opposite color as the defender's bishop, the defender may be able to blockade the pawns and draw. If both pawns can safely reach the sixth rank, they win unless one is the wrong rook pawn, i.e. the rook pawn that promotes on the square of the same color as the defending bishop. [23]
