... I imagine the viewer would be able to see that relocating his knight to d3 in the position reached above will take him back into the video ...
I would put the knight on d3 then youi have the grote kooi.
Large calf??
That's what I suggested - but I would play 4.Kf6 in your example.
Since you'd obviously set your heart on a bishop and knight endgame, a tip would be to start playing it before you actually reach it. So:
This can must faster. for example when I play it against stockfish.
That is one move faster than @AngeloPoet's sequence and would have finished on move 102. My suggestion is obviously much faster than both, finishing on move 90.
