I've just remembered about our situation in a recent match. Not sure if you'll get what I'm talking about but try to imagine this situation. You are yellows, with one ball remaining on the table. Obviously you're opponent is reds (or in our case blues). There is a blue ball approx. 3/4 over a pocket with the one remaining yellow next to it covering the gap. Another blue is covering half of the yellow. Hope you're following. A foul is committed by the opponent, therefore causing a foul snooker as you can only see one side of the yellow. Can you nominate the blue that is covering the pocket but play your yellow into it??? In our situation we were nomiating the blue incase we potted it.

A perfectly legal shot Mr Saundry sir provided a foul snooker has been agreed by the referee and you've nominated clearly the ball in question. The nominated ball then becomes your ball for that one shot but you're under no obligation to hit it or pot it if you don't want to. Obviously the exception to the rule is when you nominate the 8-ball as if you pot the 8-ball then you forfeit the frame however you can still nominate it, just not able to pot it.

Thank you for clearing that up for me my good man. As I thought, it is a legal shot. The opponent didn't agree with it at the time but we were sure that's what the rules were. While we're on the subject. what's the situation with a foul snooker when the balls in question are either touching or almost touching?

If you are already touching your own ball then you can't be foul snookered. If you're nearly touching the ball then provided there isn't another ball obstructing you from hitting the thin edges of that ball then once again you can't be foul snookered. It's a strange one as you could argue that you're that close to the ball that you can't hit both sides but the rules don't see it that way hence the reason why a lot of people try and tap up to an opponents ball when commiting a foul to make it as awkward as possible.
