@Zhai , I do not believe that it is possible for white to force a win. When chess players were worse, the proportion of games ending in conclusive results was quite high, among chess engines and players, because mistakes were common, and the person making the "next to last blunder" , would win. However, as players and engines, (and A.I's), have gotten stronger , the number of draws has skyrocketed, because neither side makes as many mistakes. With this taken into account, for me to take the view that white can force a win, would be for me to say that stockfish, or komodo, or firefly, or magnus Carlsen, blunder away a win every time they draw with the white pieces. Quite honestly, I think stockfish, and komodo, and firefly, and maybe magnus, are too good for that. Sure, they do it sometimes, but not even close to the number of times they draw as white.
