Clothes Lined Bishop in Gruenfeld

When I was a kid, mothers hung clothes on sagging clothes lines behind the house. These roped lines were low enough for moms to easily reach but high enough to keep the clothes off the ground. After dark the line was hard to see without clothes on it.

If we chased each other around and forgot about the clothes line, we ran into it about head high. That would stop us in our tracks. When that happened to me a time or two, I was more careful not to get clothes lined again anytime soon.

In a Gruenfeld Defence vs William Viveiros I was able to clothes line his dark squared bishop. I trapped it with my pawn by 12...f4. White was able to save his bishop only by giving me his knight. The open nature of the position led to very quick exchanges. By move 32, White had only pawns left. Black also had a knight.
