The browser version lets you meet the personality before buying. The installed engine plays locally, in CZUBATRONIC 2400 and your own chess software, with the full personality model.
Keres is dangerous everywhere. He attacks with precision when the position opens, holds his own in quiet manoeuvring, and his opening play has a directness that puts questions to you from the first moves.
Games against him feel balanced on a knife's edge. He does not force matters the way Tal does; he keeps the position sound and strikes when the tactics genuinely work, which makes his attacks hard to see coming.
Regular games against Keres train judgement at the border between sound and sharp. You learn which attacking ideas survive against correct defence, and how a player can be aggressive without ever becoming unsound. The eternal second of chess history is, as an opponent, first-rate.
A single game shows part of the personality. Repeated games reveal more: you begin to recognise familiar structures, recurring plans and the kinds of positions this opponent prefers. That is where the collection becomes interesting, because different personalities put different questions to your chess.
Paul Keres is the greatest player never to become World Champion, and it wasn't for lack of talent. He finished second in the Candidates tournament four times, earning the tragic nickname 'The Crown Prince' or 'The Eternal Second.' His universal style, equally dangerous in sharp tactical positions and quiet positional games, made him feared by every World Champion from Alekhine to Fischer. Some historians believe his results in the 1948 World Championship tournament and the 1953 Candidates were influenced by Soviet political pressure to favor other Soviet players, though this remains debated. He was beloved in Estonia as a national hero.
Notable: Four second-place finishes in Candidates tournaments. Appeared on the Estonian 5 krooni banknote, the only chess player ever featured on national currency.
