One of the most typical endgames which the Lomonosov tablebase
solves is that of Rook and two pawns against Rook and one pawn where the stronger side has connected passed pawns and
the weaker side has a single passed pawn which is far enough advanced to offer counterplay.
This particular endgame involving English grandmaster John Nunn, in which both sides made understandable mistakes, is quite instructive. Although not played recently, it is included here because the game is not to be found in some databases.
The game reduced to a 7-man ending after Black's 48th move and it should have been drawn.
The diagram shows the position after White's 51st move when a critical decision arose.
Black should either have tried 51...Rb3 to prevent the advance of the White king, or else 51...Rb1 to attack the white pawns from behind if they advanced. Instead Black made the natural advance of the b-pawn, which should have lost. Then at move 55 White went wrong but his opponent immediately returned the favour, after which the win became quite straightforward.
