Alt. title: "My chess is so bad, it makes me feel blue."

Good afternoon morons and moronettes, and welcome to the Saturday Afternoon Chess/Open Thread, the only AoSHQ thread with content specifically for all of us chess nerds who pay homage in the temple of Caïssa, goddess of the chessboard. And, for those of you who aren't nerdly enough for chess, you can use this thread to talk about checkers, or other games, or politics, or whatever you wish, only please try to keep it civil. Nobody wants to get caught up into a bear tree, especially if they're hungry.

Problem 1 - Black To Play (384)

Hint: Black mates in 3

And Now For Something Completely Different

We now return you to your regularly scheduled chess/open thread, which is already in progress.

Problem 2 - White To Play (BWTC 13)

Black's position is shattered and his king is on the run. How can White indulge in a little "mortal kombat" and FINISH HIM?

Hint: White mates in 3

LED Chess Set

Over on Woot, they're selling a chess set that glows with lights from internet LEDs so you can continue playing in your bunker during the zombie apocalypse.

With chess pieces that light up when they are on or near the board, this set almost seems like magic. Chess board includes a power adapter or you can use 4 AA batteries (not included).

Looks like a fun novelty set. They're doing nifty things with LEDs these days.

Problem 4 - Black To Play (52)

Hint: Mate in 6

Endgame of the Week (Endgame 276)

Black's advanced pawn looks mighty dangerous. Is there anything White can do about it, and if so, what?

Hint: White needs to force Black's king into the corner

Solutions Update

Problem 1 - Black To Play

20170121 - Problem 1.jpg
1k6/pb6/1p6/3q2pp/1p1p1b2/3P2BP/P1R4K/5Q2 b - - 0 1

1... Bxg3+!

2.Kg1 fails immediately to 2...Qh1#


If 3.Qf4 then 3...Qxf4#


Problem 2 - White To Play

20170121 - Problem 2.jpg
rn1q1b1r/ppp2B2/7p/4Bk2/3Pn1pP/3Qp3/PPP3P1/RN4K1 w - - 0 1

It's a forced mate in 3:

1.Qxe4+ Kxe4
2.Nc3+ Kf5

Problem 3 - White To Play

20170121 - Problem 3.jpg
r1b1kbnr/pp1np1p1/1qp1p2p/8/3P4/3B4/PPPB1PPP/RN1QK2R w KQkq - 0 1

White can snag Black's queen.

1.Qh5+ Kd8
2.Ba5 Ngf6

The counterattack doesn't quite work because White will capture the queen with check.

3.Bxb6+ axb6
4.Qf3 and wins.

Problem 4 - Black To Play

20170121 - Problem 4.jpg
4rk1r/pQp2p2/3p4/1Bb2P1p/3n1Bn1/7P/PPP2RP1/RN4K1 b - - 0 15


White can try 16.Rf1 but then 16...Ne2+ 17.Kh1 Rxf1# finishes him off.

17.Kh1 Nxf2+
18.Kh2 Ng4+
19.hxg4 hxg4+
20.Bh6+ Rxh6#

Unlike most of the problems I post, the move numbers here don't start out at 1 because the position is one I stole from an actual game.

Endgame of the Week

20170121 - Endgame.jpg
8/8/6p1/7p/7P/8/pk1K4/2R5 w - - 0 1

Despite his advanced pawn, Black's options are surprisingly limited. For example, advancing the 'g' pawn would be a terrible idea, but White can force him to do it by sac'ing his rook:

1.Ra1! Kxa1

Forced. Now White can box him in, thus setting him up for checkmate.

2.Kc2 g5

That was Black's only legal move.

3.hxg5 h4

And the queen race is on.

4.g6 h3
5.g7 h2

White queens first, but Black is right there with him.





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 past 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.
