In diagram #2, the rook KIRIL’S is unable to stop their advance and the white king cannot KLASS ROOK get back in time. For example, 1.Kb7 g3 2.Kc6 g2 3.Re1+ AGAINST Kd3 4.Kd5 f3 5.Rd1+ Ke2 6.Ra1 f2 0-1 or 1.Rg1 g3 2.Kb7 TWO PAWNS Kf3 3.Kc6 g2 4.Kd5 Kg3 5.Ke4 f3 6.Ke3 f2 0-1. This lesson looks at the endgame K + R vs.K + 2p. A rook is usually better than two pawns. But there are exceptions. This class covers basic endings with a rook versus two connected pawns. Pawns are “connected” if The rook is better placed behind the pawns. In diagram they stand on neighbouring files. This normally makes #3, with the white king one step closer, White can draw. them stronger because one of them can guard the other. 1.Rg8 g3 2.Kc6 Kf3 3.Kd5 g2 4.Ke5 Kf2 5.Kxf4 g1=Q The outcome of the endgame R vs. 2p depends mostly 6.Rxg1 Kxg1 ½-½. (1.Rg8 Kf3 2.Kc6 g3 is the same.) on two things: how far advanced the pawns are, and the As you can see, when fighting the pawns, the important position of the two kings. thing is to get your king closer. With the king on b3 If the rook’s king is in front of the pawns, then the rook (diagram #4), White wins. 1.Kc2! g3 2.Kd2 g2 3.Rg8 f3 wins easily. See diagram #1. White does not have a bad 4.Ke1! Ke3 5.Re8+ Kf4 6.Kf2 1-0 or 1.Kc2 Ke3 2.Kd1! g3 move. Simplest is 1.Kf2 with these possibilities: 3.Ke1! (3...Rg8? Kf2 draws) 3...g2 4.Rg8, followed by: a) 1...f3 2.Ra4+ Kf5 3.Kg3 Kg5 4.Rxg4+ 1-0 a) 4...Kf3 5.Rg7!

The rook and pawns battle it out on their own. features in the position which create unexpected tactics. The general rule is: In our final two examples, it is the placement of the kings. Do you like “surprise endings”? Two pawns on their sixth rank win against a rook. w________w w________w Black to play in diagram #5 wins by 1...f3! The rook can áKdwdwdwd] áRdwdwdwd] stop one of the pawns from queening, but not both. àdwdwdwdk] àdwdwdwiw] a) 2.Kg7 g2 3.Rb1 f2 0-1 ßwdwdwdwd] ßwdwdwdwd] b) 2.Rb3 f2 3.Rf3 g2 4.Rxf2 g1=Q 0-1 Þ$wdwdwdw] ÞdwdwdwdK] The endgame in line b with queen against rook is won for Ýwdwdw0wd] Ýwdwdwdwd] Black, but it is not easy against a good defender. That is a Üdwdwdw0w] Üdwdwdp0w] topic for another class. Ûwdwdwdwd] Ûwdwdwdwd] In diagram #6, Black to play scores the point by pushing Údwdwdwdw] Údwdwdwdw] either pawn.

In diagram #6, White to play has a clever way to win. 1.Rg6! Kd7 2.Rg4 a) 2..Ke6 3.Rxf4 Ke5 4.Rg4 Kf5 5.Rxg3 1-0 is easy. b) 2...g2!? 3.Rxg2 Ke6 is tricky. 4.Rg5! (4.Kg7?
