This was from chess.com, 1 day per move. I had black. My opponent dropped a piece on move 15, but played to the bitter end. Just for fun, I tried the B+N mate on him. I was surprised I still remembered (sort of) how to do it.
73. Kd2 {White has been down a piece since move 15, but black's somewhat indifferent endgame technique has left white still shuffling the King almost 60 moves later.} h1=N {Any chucklehead can win with a promoted Q. But do I still remember how to do this? Oh well. Even if it takes me awhile, I still have the 'insurance' pawn on f7 to break the 50-move count for me.} 74. Ke1 Nxf2 75. Kd2 Nd3 76. Kc3 Ke3 77. Kc4 Ke4 78. Kc3 {If white had really wanted to make me work, he should go to the 'wrong' corner - the one that doesn't match my B - a1.} Bg4 79. Kc4 Be6+ 80. Kc3 Ke3 81. Kc2 Kd4 82. Kd2 Bb3 83. Ke2 Ba4 {waiting} 84. Kf3 Bd1+ 85. Kg3 Ke4 86. Kh4 Kf4 87. Kh3 {He's on the edge. Now to push him to the 'right' corner, h1.} Kg5 88. Kg3 Bg4 89. Kg2 Kf4 90. Kf1 Kg3 91. Kg1 Be2 {From here it is easy - the B and K hold white's K down. Just redeploy the N to attack g1.} 92. Kh1 Nf4 93. Kg1 Nh3+ 94. Kh1 Bf3# {Woohoo. Didn't even need to use the insurance pawn.} 0-1
