Improve Your Calculation - GM Mihail Marin | Study Smyslov's Analysis

How deep did the old masters really calculate, long before computers could check their work? Many players assume accurate calculation was simply out of reach in the pre-engine era. This lesson tests that assumption with a single piece of analysis by World Champion Vasily Smyslov. Smyslov is usually remembered as an endgame virtuoso and a model positional player. GM Mihail Marin argues that his thinking was in fact deeply concrete: he steered his games through small, hidden tactical nuances and often crowned them with a combination. In Micheli–Smyslov, 1974, Smyslov delayed his natural plan of ...g7-g5 by one move, played ...Qe7 instead, and effectively invited his opponent into a trap. His own published analysis shows what he had seen: a long forcing line, a critical position where a wrong evaluation simply loses for Black, and — in the main line — the quickest possible mate, found the way Alekhine so often found them. Marin then checks the analysis and shows the one defence Smyslov missed. White could survive, though only in a very unpleasant position. Even so, reaching that critical position with a reasonably accurate evaluation at the age of 53 says a great deal about the calculating power of the classical players — and about why studying the games of "positional" champions is one of the best ways to train your own calculation. ⏱ Timestamps: 00:00 Video overview 00:45 Introduction 03:06 Micheli-Smyslov 03:38 Delaying …g7-g5 to set a trap 04:20 the planned combination 05:45 The critical position Smyslov had to evaluate 10:30 The quickest win given by Smyslov 11:25 White's only defence 📚 Topics covered: chess calculation, Vasily Smyslov, Micheli–Smyslov 1974, calculation before computers, positional vs concrete thinking, kingside attack, piece sacrifice, evaluating critical positions, quickest win, only defence, classical world champions, Alexander Alekhine ━━━━━━━━━━━━━━━━━━━━ 📘 Recommended Resources ━━━━━━━━━━━━━━━━━━━━ 🔗 Learn from the Legends (3rd Edition) by GM Mihail Marin: https://www.newinchess.com/learn-from... 🔗 Get ChessBase — the ultimate tool for chess analysis and preparation: https://shop.chessbase.com/en/categor... ━━━━━━━━━━━━━━━━━━━━ 🎓 About GM Mihail Marin Grandmaster Mihail Marin is a three-time Romanian National Champion, Olympic medalist, former second to Judit Polgar, ChessBase author, and Chessable instructor.
