White to play : Alekhine - Rubenstein, 1930

Here's something from the past, 1930, San Remo to be exact.

Sometimes, in problems like these I can see the the target but not always work out the way to reach it.

This was the case here.  There are some instant targets available, but if, like me, you focus on the wrong target initially, it can take a while to re-orient to the real one as you just keep trying to make it happen.
