Rules of snooker question?

This is for all you know it all guys out there that think you know all the rules to all the games

I could find no rules or regulations concerning the use of ether the left or right hand when using a bridge for balance in awkward shots or positions?

You see i am not nearly as clued up as most of you think and don't know all the rules to some of the finer games gentleman play  

And so without further ado

Is the below considered to be cheating?

It really doesn't matter to me...I was just wondering
