Rook Ending Lessons on being a Troll of the Bridge
The knights are trying to cross a bridge when a troll stops them and tells them they have to answer three questions.
"What is your name?
What is your quest?
What is the air speed velocity of a coconut laden swallow?"
Rook Endings can be like crossing a bridge. The defensive Rook must act like the Troll guarding the bridge, not allowing the enemy King to pass. Such was my lesson when working through Rook Ending 108 from Chess Informant's Encyclopaedia of Chess Endings Rooks Volume 2. As per usual, I set up the position against Shredder, attempting to play it out and finding out the cause of any mistakes leading to improving understanding.
Position 108: Akopian-Panchenko, Rostov-on-Don 1993
Black to Move and Draw
Attempt 1: Getting the Black King to e5 and thus not allowing the White King to support the pawn
This failed as White could get his own Rook to f6 and cut off the f-file. Then his King can come in front of the pawn to build a bridge and win.
Attempt 2: Checks from behind and limiting the White King to the h-file
