Another Black Win

4...0-0 is bad because of 5.e5 putting your knight in a bad position. 4...d6 is recommended

5...c6 is also bad due the reason I just mentioned

Often I play d6. However, I've been bored with the same old way of things. I feel Ne8 isn't awful.

This is actually incorrect. Although the knight is temporarily "in a bad position", White is clearly overextended and after 5. ... Ne8 6. f4 d6 Black is already better! 

The middlegame looks fine. You were clearly better and converted down to a winning endgame. However, you made many simplifying moves that were not the best. Especially when you no longer had any queenside pawns, this made the task of converting to a win difficult. Remember, don't make a move because the position is "still winning", make a move to improve your position!

Thanks zkman. Yeah I was upset with myself that I made him have chances for the draw. I knew there was also nothing wrong with those early moves. I didn't even need to give back the exchange according to Fritz. I could have just played Kxf7 after he had played Bg4.

At move 73, John could have drawn with ..Ra6!!

Unconvinincing?? I put the game through stockfish

 Ra6 fails to equalize the position, but it gains a draw via 3 move repetition. I don't think either player was aware of this, however.

Chess engines generally say "draw" after clear 3 move repetitions. I'm sure that, if you put this position in at an earlier point, stockfish would say black is winning.

Yeah black was winning until 72. Rb4?? and then he was winning again
