Big DataBase 2025: In search of a treasure trove

by Nagesh Havanur
6/11/2025 – Among ChessBase products the Big DataBase stands in its own right. Unlike the MegaBase it has no annotations. This paves the way for independent study and preparation, and helps the player to hone skills on his own. The present edition offers 11 million games from 1475 to November 2024. In this vast collection there are games from world championships, famous tournaments, past and present, not to mention little-known events that deserve greater recognition. There are magnificent battles, brilliancies and unknown gems all waiting to be discovered. Our columnist here introduces a few rare gems.

Winning starts with what you know
The new version 18 offers completely new possibilities for chess training and analysis: playing style analysis, search for strategic themes, access to 6 billion Lichess games, player preparation by matching Lichess games, download Chess.com games with built-in API, built-in cloud engine and much more.

Why? Why not?

The Big DataBase is often seen as a poor cousin of MegaBase as it has neither analysis nor commentary. I, for one, do not share this perception. The Big DataBase allows you to follow a game independently. After each move, you ask yourself, "why" or "why not?" You enter your own variations and try to understand how the game was won, lost or drawn. Those lines that you see by yourself are your precious contribution to the game. But are they sound? So you ask wise old "Fritz" what he thinks. The old boy knows a thing or two.

On occasion, you are not happy with his answer. Sometimes his way of thinking is too impersonal, not the way we ordinary mortals think. Then you ask the players what they think. If they tell you, well and good, otherwise the commentators will fill in the gaps. But no matter who says what, do use your own grey cells in the end for judging a position. That is what the Big DataBase is about.

Big DataBase 2025 has over 11 million games from 1475 to the closing months of 2024. The first of these games was played in Valencia, Spain, way back in 1475. The last of them in my database is Vaganian-Mikhalchishin, (½ -½, 10 moves), Vaganian Cup Blitz, 9th November, 2024. On my current count I have 11352974 games. So when you view the Big DataBase on your screen, you have nearly six centuries of chess before you.

Now a single lifetime would not suffice to see one tenth of these games. Besides, not every game would be worthy of deep attention. So one has to pick and choose. If you value your time, it cannot be at random. It is here that chess biography and history show us the way. When you read them, you come across names that you have not heard before. But when you look at their games in the Big DataBase you are astonished to find a kind of magic about them all.

For starters, we are going to see a game that was played between two strong American amateurs, Joseph Palmer Morgan and Walter Penn Shipley, way back in 1891.

Walter Penn Shipley

Shipley needs no introduction to knowledgeable readers here. He was a major figure who played an important role in the development of chess in the USA in the late 19th Century and early 20th Century. He was a friend of world champions Steinitz, Lasker and Capablanca. He was also a strong chess player.

His opponent, Joseph Palmer Morgan, was a talented player who regularly played in Franklin Chess Club Tournaments. He passed away early at a relatively young age of 32. Morgan and Shipley played a short match that the latter won. Here is the 8th game of the Match.

One player whose games should not be missed is Rashid Nezhmetdinov.

There are more than 500 games played by him here. Among others, a number of his victories over players like Tal, Spassky and Polugaevsky are included in the Big DataBase. They are all worth seeing. For starters, let us see a little-known miniature that he played way back in 1936. He was only 14 at the time.

Misha Tal admired Nezhmetdinov. During the Varna Chess Olympiad 1962 he was interviewed by Dimtrije Bjelica, chess journalist. Bjelica asked Misha what was his happiest moment in recent years. Said Misha, "I rarely felt so happy as when I lost a game with Nezhmetdinov. What a beautiful game!"

The Big DataBase also has a number of games played in training events. These competitions were a regular practice in the former USSR. Occasionally there would also be friendly contests. A case in point is the match that Misha Tal played with David Bronstein in 1966. Here is an entertaining game from the contest:

David Bronstein, Mikhail Tal

Bronstein-Tal, 1958 USSR Championship - the game ended in a draw

At times, you would also find games in Big DataBase that leave you baffled.

Years later Kenneth Rogoff, now a renowned economist, was to narrate what happened here.

Huebner had played a really important game against Karpov the round before and lost. Karpov was white and just squeezed him (it took 74 moves!-NSH). Huebner was just exhausted. He told his team captain, "I don't want to play". The team captain said, "Well, that's silly, you're white and play first board. If you're too tired, just make a draw".

In the following round, Huebner met Kenneth Rogoff, a lower-rated player. He played one move and offered his opponent a draw. Young Rogoff asked the team captain, Pal Benko, for advice. By then Huebner was a World Championship candidate, a highly rated player. Benko, of course, asked Rogoff to accept the offer. So did the young American. Unfortunately, the arbiters disallowed a one-move draw and made them play. Then Huebner started playing suicide moves. Rogoff followed suit, and he also played suicide moves in turn. By this time everyone on other tables was watching this game instead of playing their own games.

In the end, the players agreed to a draw. However, the arbiters did not take kindly to it all and declared, both payers had forfeited the game.

Fast-forward to the 21st century

So far, we have seen striking examples of play from the previous centuries. Now let us see some fine play from the present century. Young Daniil Dubov from Russia is one of the best talents in the world. Like other Russian players, his career also received setbacks on account of Covid-19 and the ongoing Ukraine war. However, he continues to play, and his style reminds one of young Tal. Here is a game played a few years ago:

Last but not least is the advance of the Indian juggernaut currently represented by D.Gukesh, R. Praggnanandhaa and Arjun Erigaisi. The form of Gukesh after winning the World Championship at 18 has been variable. Success has alternated with failure. His performance in the coming years remains to be seen. For the record, Big DataBase has more than 2100 games played by him over a decade (2014-2024). In my view currently the performance of the other two players, Pragg and Erigaisi, needs to be watched.

And how have they fared against Carlsen? For Magnus represents the ultimate test for both his peers and younger rivals.

Magnus Carlsen, Praggnanandhaa Rameshbabu

Praggnanandhaa-Carlsen at the FIDE World Cup 2023. The game ended in a draw.

First, we see a game in which Pragg beats off a dangerous attack by the world's No. 1 player.

Now for a game in which Erigaisi meets Carlsen's aggression with a counterattack:

In retrospect, I would consider the play here an unusual performance. In many games  we find Erigaisi attacking and Carlsen defending in style. It’s just happened the other day in the Norway 2025 Tournament: https://en.chessbase.com/post/norway-chess-2025-10

To return to the database, I have not said a word about the galaxy of other chess stars who have lit up its horizons… from Labourdonnais and McDonnell to Carlsen. If you look across centuries, you will see how they have all worshipped at the same altar of Caissa. Find their thoughts, feel their agony and share their ecstasy. This database comes to life. Amen.

Notes:

1) Valencia is commemorating the birth of modern chess this year:

2) Nezhmetdinov annotated the game with Tal and the annotations may be found in an excellent English translation by Douglas Griffin: https://rb.gy/wfvpxj

3) Daniil Dubov does not lack moral courage and in the following interview he condemns the Ukraine war and with youthful recklessness comments on politics:

https://en.chessbase.com/post/dubov-the-only-way-to-change-anything-in-russia-is-a-revolution

On occasion his decisions are debatable. He chose to assist Magnus Carlsen rather than his compatriot Ian Nepomniachtchi in the World Championship match 2021.
