My last stripe is 1-2" off end rail, left of center diamond. 8 ball 2-3'' off other end rail, first diamond on same side, CB left of stripe ball, middle table about one diamond from left side, tough cut shot to right corner. Opponent on 8 ball. If cut is made, shot on 8, win. Miss, lose. Bank to right opposite end (easy bank) leaves tough bank on 8. Could bank to miss and leave opponent tough but makeable bank. Bank to left corner by 8 ball leaves shot on 8 but bank miss might block pocket for opponent. Last game for all the marbles. What should I have done? ( I'm confident on cut shots,this one's about 80-90%).
