[Black "?"]
[Result "*"]
[ECO "A00"]
[Opening "Van't Kruijs opening"]
[Variation "Drawkiller"]
[PlyCount "20"]

{Nordlandia: The Drawkiller Opening is living up to it's name. Kings on oppsite sides forces attacking play for both sides. first come, first served}

[White "?"]
[Black "?"]
[Result "*"]
[ECO "B27"]
[Opening "Sicilian"]
[Variation "Hungarian variation"]
[PlyCount "39"]

{Nordlandia: Extremely rare material constellation on the board. Two same-colored bishops can protect each other. And unlike two knights, they can keep protecting each other indefinitely, even if one has to move. But that doesn't overcome their drawbacks. There is some draw tendencies, because of the chain-link effect.}

[ECO "D47"]
[Opening "Semi-Slav Defense"]
[Variation "Meran Variation, Wade Variation"]
[PlyCount "17"]

{atanh: Follow-up to VSOB  9 games 27 and 28. Stockfish actually did play 9. a3, and ended up winning. Now I'd like to see what lines engines come up with when a3 is given as last move in the book. Original description: Derived from ChessDB.cn top moves after 1. d4, circa 2019-12-04. According to Lichess and other sites, top continuations seem to be 9. O-O, and 9. e4, with 9. a3 underwhelmingly coming in third. However, while exploring CDBCN, it seems that 9. a3 might hold more promise than it first seems. Will be interesting to see what the latest engines think. }

[Variation "Tarrasch defence"]

{mrbdzz: Double-edged Tarrasch line played twice by Leela T11089 in CCCC1, resulting in
an interesting early queenside pawn storm against Komodo  ( 
https://lichess.org/fBPyQqpi  ) . Both games ended in a draw. But I've been
wondering ever since whether this rare line is actually playable for white. }
