People have attacked me for saying this, very unpopular view on the forums:D Some ask to be critiqued for their posing but then you see them compete and they have forgotten all about the advises.
Yates didn't gyrate and dance or do homosexy moves but I think his posing was very precise and well executed. No one called him a great poser though. 
Agreed - just get the job done
Things in posing that make me wince (even though Vince Taylor is one of my all time faves and did most of at some point - usually in the same routine

)
- The robot/terminator
- Lip-synching
- Body-popping/dancing of any sort
- Cupped ear begging for applause
- Posing to O Fortuna (oh brother) Once saw a regional show where no less than 6 competitors thought that they'd discovered hitting poses to the kettle drum

I once put a routine together for a guy and when we practiced the start he walked on from the left , on the day of the show they walked on from the right, he did his entire routine facing the wrong way, he even did his side chest with his back to the audience..
HAHAHAHAHAHAAA! That's brilliant

It's nerves for some people - fair play though, at least he remembered his moves - I just went totally blank when I saw all the faces and tried to remember everything at once
