Yellow is in a difficult position to run the hoop while red is in an excellent position so the best shot is to roquet blue away, ideally to a position that allows the hoop to protect red. If yellow tries for the hoop and misses, blue will send red away leaving black with a hoop running chance.
I like the clear as well. Even you don't wire blue from red, ideally it the clear is from the north boundary which is a decent distance. Black's shot isn't a gimme in case red wouldn't be able to get that clear.
However, I believe Cheryl went for and got the block. Blue tried the combo clear and didn't get red out. Red won the hoop.
For Nott's list members there was a more in-depth discussion that starts here:
And Facebook also had a bit of a discussion:
I'm with Cheryl here. The problem with clearing blue is that unless you are lucky, blue will still have a 9-10 yarder to clear red. Try for the point where yellow has a hoop shot and is blocking blue on red. Even if you fail the block, blue is unlikely to clear red to more than 8-9 yards from black, and red will be able to clear black a good distance.
