Matthias Wuellenweber - The Complete Guide to the ChessBase 26 Monte-Carlo-Analysis

by ChessBase
11/14/2025 – Monte Carlo analysis in ChessBase offers a completely new way to understand sharp or unclear positions by simulating thousands of fast engine games and revealing their practical outcomes. In this walkthrough, Matthias Wüllenweber demonstrates how the feature works, how to interpret its statistics, and how the piece-path arrows uncover typical winning and losing manoeuvres.

Data, plans, practice – the new Opening Report In ChessBase there are always attempts to show the typical plans of an opening variation. In the age of engines, chess is much more concrete than previously thought. But amateurs in particular love openings with clear plans, see the London System. In ChessBase ’26, three functions deal with the display of plans. The new opening report examines which piece moves or pawn advances are significant for each important variation. In the reference search you can now see on the board where the pieces usually go. If you start the new Monte Carlo analysis, the board also shows the most common figure paths.

0:00 – What Monte Carlo Analysis Is Introduction to Monte Carlo analysis, the dice icon, and why it gives practical, contrasting insights compared to normal engine evaluations.

1:48 – Why the Results Differ from Stockfish After several hundred games, the Monte Carlo score remains equal despite Stockfish showing a winning evaluation, illustrating the difficulty and pitfalls of the position.

3:02 – CPU Allocation & Remote Engine Advantage Explanation of parallel processing, 20-CPU usage, remote engine benefits, and how to adjust Monte Carlo parameters.

8:21 – Piece-Path Arrows & Success Colours Demonstration of the new hover-over arrows showing typical engine-match manoeuvres, with green/red success indicators, and how to disable them if needed.

11/11/2025 – Matthias Wuellenweber presents ChessBase 26’s major innovations, beginning with the Enhanced Opening Report, which automatically generates deep statistical and thematic analyses — including pioneer players, popularity graphs, and tactical training positions — all tailored by Elo level to show how openings perform from club players to grandmasters. He introduces new analytical tools, such as Monte Carlo Analysis (engine-vs-engine simulations revealing true practical chances), AI plan descriptions that explain positions in natural language, and piece-manoeuvre visualizations that display typical movement patterns on the board. Finally, he showcases improved usability and design updates, including faster ray-traced 3D boards, streamlined engine management, upgraded duplicate-game detection, and modernized database icons for a smoother, more visually appealing experience.

60m The Two Knights

This entry into the 60 minutes series concentrates on the Modern variation of the Italian game where White opens the centre early : 1 e4 e5 2 Nf3 Nc6 3 Bc4 Nf6 4 d4 exd4 5 e5!. This line can be reached by various move orders, most frequently from the Scotch 3 d4 exd4 4 Bc4. It's a sharp variation and Grandmasters such as Evgeny Sveshnikov have used it frequently,with very good results. It's a perfect line for club players to adopt which is relatively easy to learn and which contains many traps. All the main responses are covered here, including 5...d5, 5...Ng4 and 5...Ne4 and the conclusion is that is is difficult for Black to equalize in a straightforward way. Problems are being posed, which over the board might prove tough to solve.
