Can someone tell me how the system for awarding ACBL masterpoints works when one is substituting or has been substituted for? I have played 3 boards, 11 boards and as few as 1 board. If I am knocked out of the last board if my internet goes out, do I still receive the masterpoints even though it appears in the results as the substitute's master points? Thanks for your help in clarifying this! blieber
