![[Diagram]](../../diagrams/6/fed0d3de010f48527a5bc15d0e2f85aa.png) | 1970 - 1974 moves 1-10 |
Total: 416 games, Black wins 53%.

: 64 games, Black wins 41%(!). Most common alternative is b (49 games).
: 22 games, Black wins 32%. c and d both occur 18 times.
: 7 games, Black wins 43%.
: 8 games, Black wins 38%. It may seem strange that the number here increases. Reason is that MasterGo looks at all games in which this position occurs, irrespective of the order in which they appeared on the board.
: 8 games, Black wins 38%.
: 7 games, Black wins 43%. MasterGo also finds no variation till 13.
