Looks like we're going to get a fishing thread later today.

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

Easy Problem - White To Play (189)

Goal: White can force a mate in 2 moves
Hint: Get rid of the obstructing pawn

Trap Chess

I guess this is a chess variant where at certain (perhaps randomly timed) intervals, a little trap door opens up underneath a square, and if a piece is on that square, it's gone. At least, I think that's how it works. In the accompanying YouTube videos, they're speaking one of those dang furrin languages, not real 'Murican, so I don't really know for sure. Trap chess is not a variant I'd like to play, but I do admire the careful workmanship that went into making the specialized board with the trap doors underneath.

A Little More Difficult Problem - White To Play (246)

Goal: White can win a knight
Hint: Set up a fork

More Challenging Problem - White To Play (188 )

You can probably guess from looking at the position that Black is busted. All of White's pieces are pointing at his queenside, which is in tatters. So in how few moves can White force mate? Note that there are some very fast mates, but they're not forced and other mates which are forced, but a little more lengthy than is necessary. So which forced mate is the quickest?

Knight fork! White is a knight ahead, which should be enough to win.

Black's queen is guarding the b8 square to prevent Rb8#, so much of White's strategy is to try to dislodge it.

This is the fastest variation sub-tree:

1.Qxa5 Ne5 (1...Qxa5 2.Rb8#)
2.Qxa7 Rxg2+ (2...Kd8 3.Rb8+ Bc8 4.Bxe5 Rxg2+ 5.Kxg2 f6 6.Bxf6+ Ke8 7.Rxc8#)

3.Kxg2 Kd8
4.Rb8+ Ke7
5.Qc5+ Kf6
6.Qxe5+ Kg6

If 1.Qc5+ then 1...Qxc5 results in 2.Rb8#

So better is

2.Qxa7 Ke7
3.Rb7 Rd8
4.Bb5 Kf6
5.Bxd7 Rxd7
6.Rxd7 Kg6
7.Rxf7 h6
8.Rg7+ Kh5
9.Qf7+ Kh4 (9.g3 Ne5 10.Bxe5 d3 11.Qf7#)
10.g3+ Kh3

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.


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.
