OK, well first off good job on winning the game Ramned! Theoretically, starting from move 64. and on, the position should have been a draw. This would fall under our "Frontal Attack" Videos, and you should check those out again to be sure you understand some of the principals, but here it is:
- With only one final cutting off the enemy king, the result is almost always a draw.
- However, your opponent had a crucial misunderstanding about what increased his "drawing chances". And that was the plan to keep the rook behind the b-pawn (completely wrong).
- Instead of 65. Kd3 -- 65. Rd1 would draw on the spot. The idea being to start checking the king from the front, while it can't escape the pawn (because it needs to protect it). If you tried to block with your rook, his rook could move away and his king would then start coming closer.
Let me know if you have some further questions. Obviously I could go over this in much more detail, but I think if you watcht he videos on the "Frontal Attack" again, you will understand. Thanks...

Note the missed 1-move mate around 30. No need to rub that in, at least I had a valuable endgame. ;)
