There's one example I'd like to relate: When I was young there was a fairly strong junior player in my club. He was famed and feared for his endgame technique. When I asked him what had made him so strong he told me that he had only analyzed one rook ending he'd lost together with a 2300 player for about 5 hours. After that he felt he'd learnt so much that from now on he could destroy anyone in the endgame. It was purely psychological, he went looking for endgames and the other junoir players started trying to avoid them against him, often staging wild unsound attacks.
Sounds like how I learned bishop of opposite color endgames.
When I was around 1500, I played awful in the opening in a tourney game against a 1700. I was down a pawn early, and it looked like I was probably going to lose another one. But I saw that if I gave up the pawn in a certain way that traded off most of the pieces, we'd end up with bishops on opposite color squares, plus a rook each. I figured that was my best shot at a draw. So I went for that line, then planted my rook on the only open file. My opponent brought over his rook to challenge mine, allowing me to trade those to reach the bishop endgame.
It only took about an hour of playing time to reach that endgame, but we spent the next two hours maneuvering our bishops, kings, and pawns, with him trying to find a way to force his two pawns through, and me just playing defense. Eventually, my opponent gave up and agreed to the draw.
Afterward, we tried to determine if there was a way for him to force a win, but we didn't see anything. I posted it on an internet group to ask, and somebody pointed out the winning line immediately. All he had to do was keep his pawns on the opposite color squares from his bishop, but he kept pushing his pawns to the same color squares as his bishop to avoid threats from my bishop. Sounds simple when stated that way, but in practice, it required some serious careful maneuvering on his part to make progress with his pawns without losing any. I studied it, and now I understand those endgames better than any other endgame type.
