  zanzibar: Adapted from a blitz game where I squandered an advantage and let the game get a little out of control - but (accidentally) set up this little trap for White to find:

(White to move after 0...Bc8-b7)

White has one move to keep an ~ winning advantage.

  zanzibar: And seeing as it's still Monday here...

See how long it takes you to find the winning move here:

<Kempinski, Robert 2606 -- Tomczak, Rafal 2370
1-0 (44) D26m 2012.09.30
Katowice POL: TCh-POL Ekstraliga 2012 (9.1)>

Dec-19-17  Retireborn: <z> Always Check, it Might be Mate. LOL

In the other position Black is threatening ...Bc5 so I suppose White must play Qe3. I don't see what the advantage is then though, just looks unclear.

  zanzibar: <<RB> Always Check, it Might be Mate. LOL> Yes, indeed.

* * * * *

Now, a word about the blitz game position - White has to realize that his knight is the corner is a goner, since ...Bc5 threatens to trap the queen (e.g. 1.Nc7 Bc5).

(White to move after 0.Qe3xNa7 Qe8-f6)


click for larger view

The most obvious way to save the queen is <1.Qe3>, but then the material is R+2P vs. B+N, which is about equal, given White's wrecked pawns on K-side. For the record, <1.Qg8> is a little better, but not that much.

I like the accurate best move though, as it goes for an outright counter-attack, allowing Black to win the knight, but simplifying with a passer as result...

<1.c4! Bc5>


click for larger view

The idea is allow the queen to be trapped, but to counter-attack Black's queen utilizing the move in hand:

<2.cxb4 Bxa7 3.bxc6 Bxa8 4.Rhd1>


click for larger view

White not only wins an extra pawn, but obtains a dangerous advanced passer.

Dec-20-17  Retireborn: <z> Thanks. I think you have to be a master to see/calculate c4; a patzer like me who values queen safety above all else (yes, even king safety!) wouldn't get it.

  zanzibar: Some moves, like the c4 in the previous puzzle, are subtle, but still worth being proud of if you can find 'em.

The following is a forced mate, so maybe not so subtle. Still, you can be a little proud if you can find the entire sequence from here:

(White to move after 25...Bd5-e6)

Kupreichik vs A Kakageldyev, 1978 (&m=26)

(The game should have continued that one more move)

  zanzibar: Normally I try to steer clear of positions that have appeared on <CG> as PotD.

But this one is really good, and the <CG> page has something rather extraordinary in the comments -

<Static in the Interference>

X-Ray exploit par excellence.

Winning shots don't come often at this level, and if missed, can turn a win into a draw, as for this game:

<

Milanovic, Danilo 2519 -- Rogic, Davor 2510
1/2-1/2 (53) D12n 2007.01.06
Zupanja CRO: 13. Festival A (4)

>

Maybe not a stellar tactical shot, but dig deep enough and it will offer its own rewards.

<CG> has a lot of games for both these players, and really should have this one too.

  zanzibar: <Spraggett unsprings a corker>

(White to move after 48...Kf6-e5)

48...Qe6-e7 was the stiffer defense. From the game:

<Spraggett, Kevin 2545 -- Gallagher, Joseph G 2510

San Bernardino: San Bernardino (1)>

  zanzibar: Just played this one...

Black sacked two pawns to get a little bit of an attack going, and then choked by not finding the winning move.

See if you can do better.

  zanzibar: Preliminary -

The position was equal, and then White makes a misstep by not setting up an Alekhine cannon on the BR...

(Spoiler alert - stop here)

Then comes 29...Ba4 30.Qc4 Rxb1 31.Rxb1 Bxd1 32.Qxe6+ Qf7 33.Qc8+ Kh7 34.Rxa1

Black has two good moves here, but one gets has a bit bigger bang.

  zanzibar: PS- I don't think the key is a zwisch, although some comments on the gamepage say it is.

  zanzibar: An unplayed variation from <Zukertort--Anderssen (Nov 1864)>:

(Black to move after 13.Bc1-g5)


click for larger view

Zukertort (? most likely) gives this as an improvement over the game's actual 13.Nb1-d2, citing the continuation 13...Qd2 14.Nd2, "and White is better".

But Black has a much better move than the obvious 13...Qd2.

Zukertort vs Anderssen, 1864 (&m=13)

  zanzibar: Another example of old games with smashing tactics:

(White to move after 25...h6)

Looks can be deceiving - the move might appear obvious on the surface, ah, but what is it really doing?

Jan-12-18
Premium Chessgames Member
  zanzibar: This one is cooked (my use of the word meaning to take a position from a real game and slightly modify it for problem-solving):

(Black to move after 12.Qd5-e4)


click for larger view

It's taken from this scene of destruction:

G Thompson vs Lasker, 1902 (&m=12.5)

Same move works here too. As a problem the most fun line is where White has to accept all offered sacs.

  zanzibar: From one of the first recorded chess games in California's history (1856), if not the very first:

<Poisoned Pawn variation>

  zanzibar: Another early chess game from California, G3 of the match...

First, a defensive move which should be drawing, but involves some tricky calculations (not really a tactical forcing line - but sharp all the same):

(White to move after 39...Rc1-c2+)


click for larger view

Well, White didn't play the best move, instead playing 40.Kf1, another sharp position, but now Black has a winning move:

(Black to move)

The game when on to end with a little flourish of fireworks, but the unplayed defenses on move 41 are perhaps a little more instructive.

There was much Gemütlichkeit in the German club that day.

  zanzibar: This one should be pretty easy:

(White to move after 22...Ba3-c5)


click for larger view

Now, one has to wonder how Black could have missed that, especially when you see what game it came from:

<

Reti, Richard -- Euwe, Max
1-0 (30) D34j 1920.06
Amsterdam m: Amsterdam m (1)

>

R1 game of a match. Euwe was only 19 years old at the time.

  zanzibar: The above source is wrong. It's actually the game from the Amsterdam (1920) tournament, R5.
Jan-18-18  Retireborn: <z> Easy for me, because I've been looking at these games! But perhaps not that easy. It would be very interesting to know exactly when Reti saw 26.Qe5! because without that move he has nothing.

Chessbase Big 2002 gives a precise date (29.05.1920) for this game, which has helped me not to get it muddled up with the other game.

Jan-18-18
Premium Chessgames Member
  zanzibar: Yes, <RB>, it was a bit glib of me to call the entire combo "easy", as the true key does come several moves into combo.

The first move is fairly obvious, and I still wonder why Euwe played into what amounts to a self-pin. Reasonable alternatives were on the board, but I guess Euwe was in a rush to simplify.

Jan-18-18  Retireborn: <z> My guess is that Euwe hadn't seen 26.Qe5! at all (or not until it was too late) expecting 26.Bxc5 with equality.

It's also possible that he missed White's 23rd, distracted by 23.Ra1 Qxa1! 24.Bxa1 Rxa1+ 25.Bf1 Bh3 26.Rb1 Rxb1 27.Qxb1 Ba3! which does indeed simplify neatly and quickly.

Safest seems 22...Bf8. In that case if 23.Ra1? the Qxa1 trick actually wins for Black.
