“Deliberate” is a two way term. I can end up : It was not my intention in wedging he cue ball. It just happened. The other side could say “ you did it intentionally. You know better. Then What?
Trapping or Wedging The Cue Ball.
“ It is a foul if a player deliberately traps or wedges the cue ball in the jaw of a pocket”
How are the 2 players going to argue/ determine “deliberate “ play??
