Aug-19-08  Samagonka: I think my brain is jammed! Saw everything else but not that...Sh*!%
Aug-19-08  BlackWaive: Tuesday.

Candidate Moves: Nd4, Nh4+, Ne1+, Bxh3+

I noticed right away that the Knight on f3 had the potential to fork, a common theme on Tuesdays. Nd4 forces the White Queen to the defense of the Bishop, but not much else.

Ne1+ produces a Royal Fork which may only be answered by Rxe1, allowing Qxf2 and Black wins the exchange with heavy initiative.

Slightly easier than yesterday's puzzle, in my opinion.

Aug-19-08  pubplayer: <RandomVisitor>How does 20 ...Qxh3 win more quickly following 21 Qxe4? It seems to me that white now has all the bases covered.
Premium Chessgames Member
  chrisowen: Positional benoni is top dog for modern chess players, yet it seems out of hand for Hatim after Nc3. More common here is 0-0/Nd2.
Aug-19-08  RandomVisitor: <pubplayer>20...Qxh3 21.Qxe4 Ba6 22.Bxa6 Nf3+ 23.Qxf3 Rxf3 and white cannot save his game.
Aug-19-08  PuzzleMaster: Tue 2008.08.19 (Black to play. 22 ... ?)

Candidates: 22 ... Bxh3+, 22 ... Ne1+, 22 ... Nh4+

A) 22 ... Bxh3+ 23. Kxh3 Ng5+ 24. Kg2

B) 22 ... Ne1+ 23. Rxe1 Qxf2+ 24. Kh1 Qxe1+

C) 22 ... Nh4+ 23. gxh4 Qxh4 and 24 ... Qxh3+ 25. Kg1 ∞

I like 22 ... Ne1+, although 22 ... Nh4+ looks interesting as well.

Aug-19-08  456: Monday puzzle Aug-18-08 <32. ...?> C Elison vs Nimzowitsch, 1915
Aug-19-08  Sheath: A basic opening error allowed this. White is 22 moves into the game and hasn't yet done anything to develop his queen's bishop, otherwise the fork wouldn't work. Ironically, if he moves 22. Bd2, it removes the fork and still allows for the possibility of using the bishop to make black's queen uncomfortable, which is what 22. b4 was about.
Aug-19-08  Jason Frost: 22...Ne1+!! 23. Rxh1 Qxf2+ 24. Kh1 Qxe1+ 25. Bf1 Rf2 26. Qb3 Bxh3 27. Ba3 Qd2 and white is getting mated
Aug-19-08  YouRang: Finally a puzzle I could solve right away. :-)

We've got a Q+R battery aimed at white's king position, particularly f2. So, what's stopping us?

Our own knight is blocking us and white's rook is guarding f2.

What then could be better than a rook deflecting clearance sac knight fork? White must surrender the queen or suffer the terrifying consequences of ...Qxf2+.

  kevin86: I was looking in the wrong places;namely,the sacs at h2 and h3.

The text move forces the overworked rook to abandon the pawn at f2-and the move itself opens the black line to that exact square. Mate or serious material gain for black follows.

Aug-19-08  patzer2: For today's puzzle solution, Black wins with 22...Ne1+!, which sacrifices the Knight in a fork and double attack combination in order to deflect the White Rook and set up a winning double attack.

After the forcing 22...Ne1+! 22. Rxe1, Black wins with the simple double attack 22...Qxf2+ 23. Kh1 24. Qxe1 . After winning a Rook and pawn for the Knight, plus securing an attacking initiative, Black wins easily.

Aug-19-08  Marmot PFL: I was getting nowhere after 2 or 3 minutes, until I realized that with white's rooks disconnected only one could be covering e1. And that one was already tied to f2. One more move (Bb2) and it wouldn't matter but one move is enough.
Aug-19-08  patzer2: It's surprising how many tactical themes can be involved in a simple three move combination.

In this case, 22...Ne1+! involves the knight fork, deflection and double attack themes. One theme I had not thought of was discovered attack, since after the forced 23. Rxe1, Black has unmasked or uncovered a decisive attack by the Queen on f2. I also like the new category of combinations <notyetagm> has set up, which he calls "discovered deflections."

  Once: It's all been said, so no point in repeating. But, sad to say, it took me rather longer than it should to spot 22. .... Ne1+. Too many choices!
Aug-19-08  MiCrooks: I had to keep reminding myself, it's a TUESDAY! Spent the better part of a minute looking at various attacking themes which were getting me nowhere and were much too complicated for a Tuesday!

Once I told myself to keep it simple stupid I found Ne1 almost immediately. b4 was a big bad blunder but the 2200 player was already dead against the GM so maybe it was a case of hari kari :)!

Aug-19-08  mworld: darn, i saw it, then i missed it thinking that bxh3+ led to mate eventually (which it doesn't!)
Aug-19-08  mworld: patzer 2 - from the few books that i've read I think that all combinations are in fact double attacks (can't remember who to quote on that one) :)_
Aug-19-08  FizzyY: Analyzing Bxh3+ for like 10 seconds before I found Ne1+, then I discarded Ne1 and went back to Bxh3+, and then I realized Ne1+ won.
Aug-19-08  simsan: <mworld> I did the same mistake. I missed that Bxh3 Kxh3 Qh4+?? fails due to gxh4. Way below par. Recently I've been consistenly solving the monday-thursday puzzles.

I think I'll blame it on the fact that I (for reasons that are irrelevant to this forum) have hardly had any sleep the last two nights.

The fact that sleep deprivation affects the problem solving capabilities of the brain isn't exactly news, but I guess it's still interesting on some level.

Aug-19-08  Kings Indian: I am actually Kings Indian's dad. He is the chess player. I am just a puzzle wonk. I know where the pieces go on the chess board, and from there my son stomped me as soon as I taught him where they go.

So, I get some feeling of vindication when I can do the puzzles. I do best, oddly enough, on the Saturday and Sunday puzzles. It seems I get too tied up looking for the obscure angle on the easier puzzles and miss the god why didn't I see it move.

This week, I am shooting two for two. Yesterday's was harder for me. I was looking at pawn advancement first. Then, I told myself simplify. Right away the rook slide jumped out. Loved it.

Today was instantaneous. I think I got lucky by going to the Ne1+ first, before trying the also enticing bishop diagonal. When the Ne1+ move proved to be devastating to white, I figured that must be it. It was!

  Once: <mworld> You might be thinking of Averbakh as reported in Yasser Seirawan's Winning Chess - Tactics. Seirawan said: "Averbakh considers that almost all combinations are based in some way on a double attack."

He then gives this quote from Averbakh: "If we regard the term "double attack" in a broader sense than has been done up to now by theoreticians, namely not merely as a two pronged attacked but as a combination of attacks and threats, we notice that the double attack in one form or another is the basis of most tactical operations."

But I don't think that we can say that all combinations are based on a double attack. Take this hackneyed example:

It's mate in 5, but as black doesn't have a single choice in tbe sequence I would argue that there is no double attack.

1. Rh8+ Kxh8 2. Rh1+ Kg8 3. Rh8+ Kxh8 4. Qh1+ Kg8 5. Qh7#

Aug-19-08  Salaskan: Sheesh, this one's really easy, but I stopped thinking after I saw 22...Bxh3+ 23. Kh1 (23. Kxh3?? Qh4 24. Kg2 Qh2#), not seeing that 23...Qh4?? would simply be met by 24.gxh4. Like simsan, maybe it's due to sleep deprivation, I slept 3 hours this night. I was also thinking about 22...Nh4+ to open the g-file for the queen and rook, but white can hold in that line.
Aug-19-08  TheaN: 2/2

Hm, took a while to throw Bxh3 and the likes away, seeing the winning fork. I don't think it's necessary to see as far as I'm going, but it's not too hard.

<22....Ne1> nice, not great. 22.b4?? is just careless by White, and Black says thanks in return. Black forks Queen and King, and not capturing is an immediate by Nxc2, so I leave it out.

<23.Rxe1 Qxf2> the idea is actually removing the guard, the guard of the square Black wants to control with any cost. In this case, it looks like it's costing a Knight, but the immediate strength of this control is shown to see it actually wins AT LEAST the exchange.

<24.Kh1 Qxe1> I guess this is the end of the Tuesday puzzle on its own, because Black has won either QvsN or RvsN with forcing moves only. However, for anyone who is looking further, the combination is not dead, actually. With four legal replies, White seems to have plenty, but it all ends quick.

<25.Kg2 Rf2 0-1>

<25.Nf1> both interposions are quite identical, but I'll list both anyway as there are some differences.


<26.Kg2 Rf2 0-1>

<26.Kh2 Rh1 27.Kg2 Bxh3 0-1>

<26.Bxf1 Qxf1 27.Kh2 Qxh3 28.Kg1 Bd4

29.Be3 Bxe3 30.Qf2 Qxg3 31.Kh1 Bxf2 32.Rb3 (Rg1 Qh3) Qg1 0-1

29.Qf2 Qxg3 30.Kh1 Bxf2 31.Bf4 (Rb3 Qg1) Qf3 32.Kh2 Qh3 0-1>

"optimal" play by White for either 29.Be3 or 29.Qf2 results in -#5 after 26....Qxf1.

<25.Bf1 Rxf1> familliar...

<26.Kh2 Rh1 27.Kg2 Bxh3 0-1>

<26.Kg2 Rg1 27.Kh2 Rh1 28.Kg2 Bxh3 0-1>

<26.Nxf1 Qxf1 see variation BC 0-1>

<26.Kh2> just not interposing anything is White's best bet (if done the right way, not with Kg2), as it does not allow the Rook in on f1 with tempo, leading to the deadly mates stated above.

<26....Rf2 27.Ng2 Bxh3!> but nonetheless, Black prevails by developing his final piece, and ending the game pretty forced.

<28.Bf4 (Kxh3 Qh1) Rxg2 29.Kxh3 Qf2 30.Rh1 Qxe2 > John seems to have a more gaining variation for Black, but I believe it this far. Quite a lot, actually. Good luck deceiphering, but Black wins at least two pieces.

Aug-20-08  Kasputin: Material is even.

Candidates: ...Nd4 ...Bxh3 ...Ne1+

22 ...Ne1+
23. Rxe1 (or else white loses the queen) ...Qxf2+
24. Kh1 Qxe1+
25. Kh2 (if Kg2 ...Rf2#) ...Rf2+
26. Ng2 and then black can capture the e2 bishop with either the rook or the queen (the queen if black wants to simplify things and force a trade of queens). Up a rook and a pawn black has an easy win and threatens things like ...Bxh3 as well.

It took me a little while to see ...Ne1+ (not too long but not immediately either). For some reason it didn't exactly jump out at me, but, once I considered it, there really wasn't anything else.
