GM Anna Muzychuk (UKR)

TheJamesMadison will be along later with the movie thread.

As always, the chess/dress pr0n thread is an open thread, so there is no such thing as an off-topic comment.

Advanced Problem - White To Play (573)

White has this game won. Fill out the decision tree as completely as you can. How long is the longest branch?

This wool hooded cape was know as a cardinal due to its vivid red hue. It was a popular garment for American colonists. By the latter half of the 18th C, it became one of the few garments that could be bought ready-made, available both in England and the colonies. Via @metmuseum pic.twitter.com/wjvB3GdruT

Note: that cryptic line of letters and numbers you see underneath each board diagram is a representation of the position in what is known as "Forsyth-Edwards Notation", or F.E.N. It's actually readable by humans. Most computer applications nowadays can read FEN, so those of you who may want to study the position, you can copy the line of FEN and paste into your chess app and it should automatically recreate the position on its display board. Or, Windows users can just "triple click" on it and the entire line will be highlighted so you can copy and paste it into your chess app.

___________

So that about wraps it up for this week. Chess thread tips, suggestions, bribes, rumors, threats, and insults may be sent to my yahoo address: OregonMuse little-a-in-a-circle yahoo dott com.
