I like playing against tight/conservative players... Players who will not ever shoot at their hole when they can't play safe also...gives me much more latitude in my shot selections...
Playing against tight players who also squeeze you and take an inordinate amount of time to find the absolute correct shot is totally different IMO.. They look over every conceivable option every time it's their shot and are a total bore to play against...it is of course their prerogative to play at whatever pace they choose, as there are no rules in place to govern slow play... I just quit the game & cross them off my play list... Life's to short, especially at my age...
Rhythm plays a big part in some people's arsenal and players who use the constant delay tactic ( whether consciously or unconsciously ) are IMO to be avoided...
