Opoos - I have over seen the B-flat-symbol in the sheet music... (And didn't turn on my piano, with sound it is weird anyway)...
If my pinky is forced to go up to the Bb, there is no easy slide down is in my previous post.
In this case, the sliding middle finger has a very steep angle and even the fingernail is touching the G. Here, I don't play the black key at the very end, I am just playing it near the end and slide from F# sideways to the G.
I recalled this sequence several times, and my muscle memory always used the steep middle finger angle. No matter if I slide or not. My middle finger is always that steep. I don't know why I am doing it this way, but probably I figured out it works better with my sausage fingers.
