Longest Sea-serpent?

Chernev called them “SEA-SERPENTS”. What are they? Simply put, they are chess games exceeding 100 moves. The name reminds one of the long list of moves each player has to record in a tournament game.

Which brings up the following question: “Just how long is the longest game in chess?”

Is it 120 moves? 150 moves? Not even close.

175 moves? Getting closer.

200 moves? Still longer.

250 moves, right?

Nope!

The longest game in history is whopping 269 moves, played over 23 ½ hours.

It seems ridiculous, but it’s true. I was amazed when I goth news – even more when I finally got the score.

I made some notes to the game and added a few diagrams just in case you get lost. I also added a PGN file (minus the diagrams of course) – for those of you who rather push buttons than pieces (or don’t have a readily available set).

Let’s go!
