It took me 8 (!) minutes to find the solution. I saw it all of a sudden. The pattern is highly familiar. As usual. Of course it is an excellent opportunity to get rid of those 8 minutes. That is the kind of speeding up we are looking for. In those 8 minutes, I'm waiting for the right trigger to fire. I tried to influence it by verbal (logical) reasoning. But reasoning is by its very nature a terrible slow process.
When you look at the board, you eyes are seeing only a very little spot really sharp. We are not aware of that, since we assume that we see everything sharp. When investigating the board, it is notorious problematic to see the "long moves". The moment I zoomed out, mentally, while physically looking to Re2, I became aware of both the queens. Exactly that moment the trigger fired, and shouted "NOW is the time for an X-ray attack!!".
