I played the Manchurian system again today.
There are several possible continuations:
D–B, or the Ussuri Line
C–D, or the Argun Line
C–A, or the Amur Line
Recently I’ve been playing the Amur, but I’m thinking of trying the Argun soon.
In the game, White played the vulgar exchange A–B. One might think that this sequence relies on a ladder and that Black must now play X and not Y, but actually Black can still play Y.
White still loses about 15% WR, but that’s the same as what the bot claims I lost from playing the Manchurian to begin with, so I can’t criticise. It’s only a point or two anyway. In any case, White should probably play C directly.
This ladder necessary for White to capture tightly. The game result looks better for White, though, even if he does have the ladder.
There are some complex bot variations possible, but the game could easily proceed simply like this:
That looks about even, or, more accurately, a little better for Black.
The game continued this way, though, with some mistakes from both sides. I was happy with this, noting that A and especially B are inefficiently placed.
