Knock Knock!

What do the world's top grandmasters do while waiting for the start of the next round at the Tradewise Gibraltar Chess Festival? They tell jokes!

As GM Peter Svidler said to GM Vassily Ivanchuk,

Knock knock!
Who's there?
Pizza!
Pizza who?
Pete's a great guy!

And the Ukrainian GM replied,

Knock knock!
Who's there?
Chuck!
Chuck who?
Chuck mate!

Not to be outdone, the seven-time Russian champion said,

Knock knock
Who's there?
Russian!
Russian who?
Rushin' to tell bad jokes!

Then the exchange became political.

Knock knock
Who's there?
Putin!
Putin who?
Putin me to sleep!

This was quickly followed by,

Knock knock
Who's there?
Crimea!
Crimea who?
Crimea river!

Just as the exchange was about to turn politically incorrect, the round started. • For a more conventionial Flickr Friday post on a previous edition of the same event, see Gibraltar's Tradewise Chess (February 2014).
