Saturday Afternoon Chess/Open Thread 01-07-2017The Folded Chess Set Sandro Del Prete, 1975
My computer beat me at chess... so I beat it at kickboxing.
This problem has two similar, but distinct, solutions. Find both. Hint: Mate in 2 r3qb1r/pppbk1p1/2np2np/4p2Q/2BPP3/2P5/PP3PPP/RNB2RK1 w - - 0 1 Problem 2 - White To Play (104) Looks like Black is about to get really nasty with 1...Qc2+ followed by 2...Qa2#. So how does White "do unto him" before he himself gets done unto? Hint: White mates in 4 6Q1/B7/8/8/8/1p6/1K2k3/3q4 w - - 0 1
Apparently, it's more sinful than gambling: Turkish televangelist Ahmet Mahmut Ünlü, popularly known as “Cübbeli” Ahmet Hoca (Robed Ahmet Hoca), has raised eyebrows by claiming that playing chess is more sinful than gambling, daily Hürriyet reported on Jan. 2. First, I hope that I'm not the only one who thinks that there is something inherently funny about the phrase "popular Muslim televangelist", and the image that it suggests is extremely silly. And even though the comedy potential for this is obvious, there will be no SNL skit based on it any time soon. But as for the chess hatin', I tend to think that this boob probably played against some local hotshots down at the coffeehouse, got his butt kicked, and is now religicizing his butthurt. One wonders what Mahmut thinks about the Arab Muslim players and masters (including some of the caliphs) who had no problem reconciling their love of chess with the tenets of Islam, and were even responsible for introducing chess into western Europe when they conquered the Iberian peninsula. Lastly, I did not know that Muslims used prayer beads. But they do. Their beads look kind of like a rosary, only no crucifix.
Hint: White mates in 3 5b1r/rpk3p1/p1p1Bpnp/2B5/4P3/8/PPP3PP/2KR4 w - - 0 1
Actually, he won't. It's just that I'm on the House of Staunton e-mail list and their "4th Day of Chessmas" offering is the Steiner Series Chess Pieces. So who is Steiner? The set...was designed by the enterprising Hungarian-American International Master Herman Steiner, near the end of World War II in Los Angeles 1945...Steiner’s association with Jacqueline Piatigorsky was a relationship of special importance to American chess history. As it turns out, it was also a relationship that catapulted Steiner’s chess set design into immortality. So this is a replica of the set designed for the Piatigorsky Cup tournaments in 1963 and 1966. The 2nd of these was the one where Fischer finished in second place, a half point behind Boris Spassky. The set weighs over 5 pounds, so it's got that going for it. But I'm not overly fond of the aesthetics of the pieces. The rooks are especially unattractive. They remind me of a "no-neck" bar bouncer/union goon. The knights are fine, but the bishops are kind of ugly. A 5" king is impressive, though. So, all in all, I think I'll spend my $995 on something else. But what's cool is that over on the HoS site, the pics of these pieces are interspersed with cool-looking vintage photos of their predecessors actually being used at the Piatigorsky Cup by tournament by Fischer, Spassky, and Petrosian.
What are some good lines of play for Black? Hint: Black can win the exchange 3rr1k1/bpN3p1/p2Q1pP1/P2P4/2P5/6P1/3q1P2/4RRK1 b - - 0 1
It's White to move. Is this a win, a draw, or a loss fow White? Show your work. 8/p1p4k/2Pp4/P2Pp3/4P3/2K5/8/8 w - - 0 1
Solutions Update Problem 1 - White To Play r3qb1r/pppbk1p1/2np2np/4p2Q/2BPP3/2P5/PP3PPP/RNB2RK1 w - - 0 1 None of the pieces around Black's king are actually protecting it. In particularly, he is fatally week on the dark squares. White can easily take advantage of this. In fact, he can mate in two ways, either with the queen: 1.Bg5+ hxg5 Or with the bishop: 1.Qg5+ hxg5
6Q1/B7/8/8/8/1p6/1K2k3/3q4 w - - 0 1 1.Qg4+! 1...Ke1 If 1...Kd2 then 2.Qd4+ Ke2 3.Qe3+ Kf1 4.Qf2#. The King fleeing to any other square will result in the loss of the queen. 2.Qg3+ Ke2
5b1r/rpk3p1/p1p1Bpnp/2B5/4P3/8/PPP3PP/2KR4 w - - 0 1 1.Rd7+ Kb8 But Black doesn't have to play 1...Kb8. The c8 square is also available: 1...Kc8 But the result is the same.
3rr1k1/bpN3p1/p2Q1pP1/P2P4/2P5/6P1/3q1P2/4RRK1 b - - 0 1 This is not a simple position. There are a number of threats and counter-threats. One of the approaches Black could take is: 1...Qxf2+ Threatens ...Rxe1. 2.Rxf2 Rxe1+ And Black is pretty much a rook up. With this advantage, he should win. This is the "not bad" line. But there's a better one.: 1...Bxf2+! Black can't immediately take the queen. 1...Rxd6 is met with 2.Rxe8# 2.Kh1 Qxe1 Not 2.Rxf2? Qxe1+ 3.Rf1 Qxg3+ 4.Kh1 Rxd6 3.Rxe1 Rxe1+ At this point, Black is so far ahead on material he can simply take the knight and lose the exchange, which leaves him in an even better position. 6...Rdxe6 So, looking at the piece count, Black now has a rook and a bishop, and White has bupkis. Looks like it'll be an early night. My chess app suggested Qf8+ for White at move 3. So I played it out: 3.Qf8+ Kxf8 Which is a similar position to the previous line. The strategy for Black is the same: lose the exchange and pick up White's last remaining piece. 7...Rxd5
8/p1p4k/2Pp4/P2Pp3/4P3/2K5/8/8 w - - 0 1 Short answer: Black will win. The key for these positions with these competing pawn chains is the pawn at the base of the chain, because that's the one most vulnerable to attack. So can White get to the base of the Black pawn chain on c7? The b-file is open, so that is his fastest route. Let's take a look: 1. Kc4 a6! And Black effectively slams the door on White's aspirations for a b-file breach. There is now no way for White to get through, so he has to go around the other way: 2.Kd3 Kg6 White would very much like to get to the f4 square, but can't. As a result, he will be forced away from his pawn chain. 5.Kg2 Kg4 OK, so White loses time by trying to invade on the b-file. Knowing this in advance, should he instead just move immediately to the kingside to block Black's own invasion? That would be a sounder plan, but that, too, falls short. 1.Kd3 Kg6 Again, White runs into the same problem: he can't get to the f4 square, so he will be unable to defend his pawn chain. 4.Ke3 Kg4 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.
