I agree. So Junior was correct in its evaluation after 14.-Rxe3 but had to follow up with 16.-a5, which it didn't. Black has to play very exact to get a draw if he chooses to swap rooks. Even if white plays a5 before Ke4, black just manages the draw. As a rule I think it's bad for programs (and humans)to change rooks in such a position. /S > >[D]8/2p5/pp2k1p1/2p3P1/P1P1KP2/1P6/8/8 b - - 0 16 bm a5 > >Uri
