I understand conceding is not allowed in BCA eight ball league. However people do concede. Last night in eight ball my opp scratches on eight, leaving eight on table with me having two balls left. Shakes my hand, walks away and says good game. Thats conceding which is not allowed!? His team mates say I must take my bih and run out to win, so to keep peace I do so. Talking to my captain, who is a ref he says yes I could lose if I also sat down and didn't return to table and run out. But my opp clearly broke a rule by conceding and doing so could win him the game? That's crazy! Many people concede by raking the eight off the table or saying that's good and shake hands, another concession with no issues I suppose. This rule needs to change, makes no sense. I knew the rule when eight is still on table but he conceded, shook hands and walked away. Clarification on all types of conceding please.
