From Norway Chess, only 6 days old. A fresh practical novelty in a line that had almost disappeared from top-level practice. After 8.Re1, you have to go back to 2010 to find 2500+ games in this branch. Then @WesleySo_ played 12...Nb4.
@WesleySo_ The Novelty was real — even if the follow-up was not fully clean: after 13.a3, ...Bd6 first and only then ...Nc6 was more precise than 13...Nc6?! CheckMeta64 had this surfaced just the day after the game.
@WesleySo_ 12...Nb4 was known from one correspondence game, but not from practical top-level play. Black had previously relied on 12...c6 in Marshall style, but after 13.Qf3!, that line fell out of favor.
9...Na5!
Black is ready sacrifice the e5-pawn.
If 10.Nxe5 → 10...Nxb3 11.cxb3 Bb7 — active pieces and pressure for the pawn.
In the game: 10.Ba2 d5 11.Bxd5 Bxd5 12.exd5 Bb7. Black was already better.
Slagboom (2334) vs Van der Werf (2384) · ch-NED Qualification 2026
Anti-Marshall territory.
White has just played a waiting move.
The novelty in this position had already appeared in 13 correspondence games.
Still, it is not the move most players would immediately consider.
Can you find Black’s idea?
@WesleySo_ had a nice chance to play an idea I found a couple weeks ago using @CheckMeta64 the point is that after 14. ... Ba6 15. cxd5!? Bxf1 16. Qxe4 exd5 17. Qe3! White looks for Nf5 and the position is quite scary for Black and specially refreshing on a very dense line
White plays 5.e3 — looks quiet. Then comes 7.f4!
A novelty that completely changes the character of the position.
From: Vogel vs Nemitz, Rudolf Teschner Mem 2026 🧵
A really interesting app I've using lately! Funny enough I had this analyzed recently as my new @chessable course 🧐🧐.

Not every interesting novelty comes from elite chess.
After 7.Bg5, White usually tries to force Black away from the setup with 7...f6 or 7...Be7. But in Pi, Aiying 1994 — Lu, Yichen 1541, Black found: 7...Qc8!
Black keeps the spirit of the variation and asks White to prove the point of Bg5. A game like this would normally be easy to miss. But the idea is not easy to dismiss. CheckMeta64 flagged it instantly:
Theory Impact: 96% High
