Not the three-minute mile

The difference between training with apps and websites compared to books, is that what you do is stored and available for checking, even if you don't remember that you can.

For whatever reason, I decided to check my previous attempts at the below problem, since it was a good problem to solve and took me some time to work out

White to move

I was amazed to find this was my second attempt, and that I had solved it correctly both times, but surprisingly, the second attempt took 2+ minutes compared to the initial 4+.

Conclusions can't be drawn from 1 problem, but certainly, I sense that progress is being made, albeit slowly.  

More importantly, I also seem to gain greater satisfaction and enjoyment during games as well.
