What does a grandmaster actually do when he wants to refresh an opening? GM Alvar Alonso Rosell had been away from the Caro-Kann for a while and wanted to catch up: not by revisiting theory he already knew, but by seeing what had actually changed since he last played it.
So he turned to CheckMeta64's novelty recipes, curated searches designed to surface the most interesting recent novelties in any position. From the results, 21 games made the cut: ideas that are instructive, dangerous, or simply useful to know if you play the Caro-Kann from either side.
This post is the hub of the series. Below you'll find how the selection breaks down, links to the detailed parts, and three complete games to give you the flavor.
What the selection covers
This is a curated selection, not a statistical study: 21 games Alonso Rosell found worth studying. That said, here is where they landed:
| Variation | Games | Where |
|---|---|---|
| Advance with 3...Bf5 | 9 | Part 2 — coming soon |
| Advance with 3...c5 | 4 | Part 3 — coming soon |
| Fantasy Variation (3.f3) | 3 | Part 4 — coming soon |
| Exchange Variation | 2 | Part 4 — coming soon |
| Two Knights and other sidelines | 2 | Part 4 — coming soon |
| Main line with 4...Nf6 | 1 | Covered below |
The Advance Variation alone accounts for 13 of the 21 games in the selection. If you meet 3.e5 as Black, or play it as White, that is where most of this selection is concentrated.
1. Elite preparation: Nepomniachtchi – Erigaisi
The headline game of the selection. In the crazy 3...c5 4.Nf3 cxd4 5.Qxd4 complex, Nepomniachtchi uncorked the deceptively quiet 12.Nf4, and Erigaisi, tuned for the usual chaos of this line, went wrong immediately with 12...Nd4?.

Novelty. It has a nice purpose: Black is used to the craziness here, so he doesn't look for a calm move.
The full analysis, including the absurd 12.Nc3 line where best play ends in a draw and why 12...e6! saves Black, is coming in Part 3 of the series.
2. A new idea in a dense line: Bharath – Tan
The Bayonet Attack 4.g4 against 3...Bf5 leads to some of the sharpest positions in the whole Caro-Kann. Here White's 8.Nh3 is, in Alonso Rosell's words, nice because it is a new idea in a dense line: objectively, many moves work for Black. Except the natural one Tan played: 8...Nf6?.
3rd 3-0 Thu 30th Apr 2026 · 30 Apr 2026
Novelty. It is nice because it is a new idea in a dense line, but many moves work for Black.
The rest of the 3...Bf5 material (nine games in total) is coming in Part 2.
3. The modern main line fights back: Nguyen – Mahdavi
The only game in the selection from the modern main line with 4...Nf6 5.Nxf6+ exf6, and it earns its spot: Mahdavi followed the risky 11...b5 from Duda–Carlsen, and then improved on known practice with the quiet 15...g6!. The viewer includes Alonso Rosell's notes on the alternatives Black has scored well with, and the earlier game Quparadze–Eljanov that this preparation improves on.
Titled Tue 5th May 2026 · 5 May 2026
Novelty.
Takeaway: novelties aren't only for the elite. This was a Titled Tuesday game where the higher-rated player brought deep preparation to a "quiet" main line, and it decided the game.
The rest of the series
- Part 2 — Advance with 3...Bf5 (9 games): coming soon.
- Part 3 — Advance with 3...c5 (4 games): a quiet novelty in a chaotic line, a bad novelty punished, the tricky 4...Bg4, and a sneaky move order in the 4.c4 variation. Coming soon.
- Part 4 — Beyond the main lines (7 games): the Fantasy Variation 3.f3, the Exchange Variation, and the sidelines. Coming soon.
Each part will be linked here as it goes live.
