Nice comments. However, I would take issue with the following points:
You say that 21...e4 was better than 21...Qf6. I fail to see that. After
21...e4 22.h4, black is dead. In fact, it appears that 21...Qf6 is the best,
since it at least draws, and at best, wins. Junior's b4 is losing,
notwithstanding your later assertion that 26.h3 draws (after f4).
Junior thought for 9 minutes on move 22.b4. In that time, with your hardware,
it's regrettable it couldn't find Nf3. I don't understand your point about
Junior being happy with b4 because it pondered on the wrong move.
Returning to your point that 26.h3 would equalize, I don't see that either. And
certainly, Junior wouldn't have played 26.h3 after 25...f4.
Perhaps you could supplement your assertions with analysis, so that a poor
fellow like me could replicate and validate your lines.
