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.
Beginner Problem - White To Play (1166)
Extra credit if you can find more than one solution

Hint: Black's back rank is weak

"Desiree, Oh Desiree..."
Intermediate Problem - White To Play (1167)
How many mating lines can you find?
Goal: Force mate in 5 moves, maximum
Hint: This is simply brute force on the back rank
2br2k1/2r1q2p/2P1p3/pp2Pp2/1p3PBQ/2p3R1/P6P/6RK w - - 0 1
Advanced Problem - Black To Play (1134)

Problem Solutions
Beginner Problem - White To Play
7k/6p1/2pb1pPp/p1p1q2P/P1P2r2/3Q4/1R4K1/3R4 w - - 0 1
1.Rb8+ Bxb8
2.Qd8+ Qe8
3.Qxe8#
That's the one most everybody sees. But there's also this one.
1...Qe8
2.Rxe8+ Bf8
3.Rxf8#
It's hard to think about throwing your queen away first thing.
Intermediate Problem - White To Play
2br2k1/2r1q2p/2P1p3/pp2Pp2/1p3PBQ/2p3R1/P6P/6RK w - - 0 1
1.Bh5+ Kh8
2.Bf7 Qg5
If 2...Qxh4 then 3.Rg8+ Rxg8 4.Rxg8#
3.Qxg5 Rxf7
4.Qg8+ Rxg8
5.Rxg8#
or 4.Qxd8+ Rf8 5. Qxf8#
Advanced Problem - Black To Play
3q1rk1/5pp1/3p3p/1Q1N3P/2p3P1/R4n1B/rPP5/2K4R b - - 0 1
There may be more lines than these, but they all kind of look similar:
1...Ra1+
2.Rxa1 Qg5+
3.Nf4 Qxf4+
4.Kb1 Nd2+
(and this is where it starts looking smothered)
5.Kc1 Nb3+
6.Kb1 Qc1+
7.Rxc1 Nd2+
8.Ka2
...and White escapes being smothered, but to no avail:
8...Ra8+
9.Qa6 Rxa6#
Here is the line based on the white king going to the other escape square on the third move:
3.Kb1 Nd2+
4.Kc1 Nb3+
5.Kb1 Qc1+
6.Rxc1 Nd2+
7.Ka2 Ra8+
8.Qa4 Rxa4#
Hope to see you all next week!

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.
