Monday’s 5-second tactics

timeless

First some oldies (but goodies):

gm  Lengyel,L

1gm  Ivkov,B

Beverwijk, 1964.  White has a dominating position with active pieces.  Almost every Black piece is on the wrong square! In particular, the White Rook on c1 and the Black King on f8 give motif for a quick kill.  Do you see it?

gm  Pietzsch Wolfgang

Harrachov, 1966.  Position after move 39.  Probably in time trouble (the time control was move 40), the last few moves have seen the Black position disintegrate.  Most worrisome, from the Black perspective, is his King position: the White Knight pins down his majesty to the corner.

The rest of today’s exercises are from the last few rounds of the World Júnior in Turkey.  Good luck!

Velten, Paul  2427

Saiyn, Zhanat  2337

Position after 27.Be5, attacking the Rook.  White had earlier sacrificed a pawn for the initiative, and now Black should retreat his Rook to d7, where it defends the Queen (or even 27…Rd8).  Then, should White want, he has a forced perpetual check: 27…Rd7 28.Rxg7+! Nxg7 29.Nf6+ Kf8 ( 29…Kh8?? 30.Qe4! wins for White ) 30.Nh7+ Ke8 31.Nf6+ and Black should return his King to f8.  It is hard to believe that White has better than this.

HOWEVER, Black played 27…Rd5?

9b

While this does attack the White Bishop, it does not add protection to the Black Queen!  A very important , if subtle, detail….

HOW CAN WHITE GET A BIG EDGE?

Du Plessis, Heinco  2050

6a

Asgarizadeh, Ahmad   2357

Position after 18 moves of play.  White has obvious intentions of attacking on the Kingside (look at his Rook on g3!), but Black’s last move (18…Bd4) was designed to de-activate the Bishop on b2 and slow things down (19.Qh6 can be met with 19…f5).  Unfortunately, Black’s basic idea does not work:

19.Ne4!!

6d

Funny how  chess constantly reminds us that the game is –fundamentally– a struggle of ideas!  White’s last move simply  ignores Black’s idea–leaving his Bishop enprise– and threatens to intensify his initiative with Nf6+.

If now 19…Bxb2 20.Nf6+ Kf8 ( 20…Kh8 21.Rh3 h6( or 21…gxf6 22.Qh6! mates ) 22.Rxh6+! ) 21.Nxh7+ Ke8 ( 21…Kg8 22.Nf6+Kf8 23.Rxg7 is soon mate ) 22.Rxg7!  and White has a powerful initiative that can not long be held at bay, for exemple 22… Rd4 23.Qf3! Rc8 ( 23…Kd7 24.Rxf7 )(23…Kd8 24.Rxf7 Qc5 25.Ng5 ) 24.Nf6+ Kd8 25.Qh5 Rc1 26.Rxc1Bxc1 27.g3 Rd7 28.Nxd7 Nxd7 29.Qxf7 and White will have a winning ending

19…Kh8!?  20.Nf6!

6B

Anyway(!) even though it is not check.

White threatens, amongst other things, to continue his attack with 21.Rh3, with winning variations similar to the last note.  Black tries his best to avoid that and resist in anther fashion:

20…PxN!?

6c

In the game White continued imprecisely with 21.Bxd4?! f5! 22.Qh6 Rg8 23.Bc5 Qd8 24.Rxg8+ and now with 24…KxR! Black could still hope to successfully resist.  INSTEAD, in the position above, White has MUCH better!

WHITE TO PLAY AND WIN!

im  Wang,Richard

Position after 28 moves of play.  The Canadian star has clearly outplayed his opponent , who can barely move.  Especially, the open g-file is paralyzing.  HOWEVER, Black has every square protected and then again…Wang needs a fresh idea in order to bring Black to his knees…

WHITE TO PLAY AND WIN!

Zhanbai Uulu, Zhokhar  1843

Lozhnikov, Vyacheslav  2339

Position after 24 moves of play.  Opposite side castling.  Clearly White is better  and–to boot– he has the initiative.  However, Black can still put up strong resistance should White underestimate his task…one needs to be very precise when going in for the kill: a trapped animal is always dangerous!

WHITE TO PLAY AND WIN!

Zor, Alber Kadir   1948

Carneiro, Vitor Roberto Castro   2250

Position after 24 moves.  Black is attacking the White Queen and threatening, in some lines, to block things with Nf4.  There is no doubt that White has a big positional advantage in this position, however, but White must play with energy and courage in order to overcome Black’s resistance.

HOW SHOULD WHITE PROCEED?

AN ENTERTAINING FINISH!

im  Firat,B

Nasanjargal,U

Position after 24 moves of play.  It is clear that White has a solid positional edge, given Black’s lack of counterplay and weakened Kingside.  The simple 25.Ng6!? seems without risk: after 25…Kf7!? (25…Qf7  26.Be2 and Bh5 is awkward)  26.g4! and 27.f4! and Black has a diffcult game to try to  hold.

INSTEAD, no doubt driven by fiery passion, White preferred to take risks and play for the beauty prize!

25.Bh3!?  fxe5 26.Rxd5! Qxd5!

11

Taking with the Rook or Knight would allow 27.Bxe6+ followed by the White Queen infiltrating…

27.Rxe5!

12

All very pretty!  BUT, it is not clear that any of this should win by force against best play

27…Bxe5! ( 27…Qd6? 28.Bxe6+ Kh8 29.Qg6 etc ) 28.Qg6+ Kf8

13

Instead, 28…Bg7!  29.Bxe6+ Qxe6 30.Qxe6+ Kf8 31.Bxg5 Rd7!? 32.Bf4 Rad8 33.g4 will transpose into the next note

29.Bxe6

14

Here Black MUST the Bishop: after 30…QxB!  31.QxQ  Bg7  32.Bxg5 White is a bit better, but it is far from clear that White should win the game.  With 2-Rooks and a Knight for the Queen and pawns, Black can put up strong resistance.  HOWEVER, probably short of time and drained from the impressive series of sacrífices on White’s part, Black makes a terrible mistake and loses immediately…

29… Qf3?

15

30.Bf4!! Qb7 ( 30…Ke7 31.Qf7+ Kd6 32.Bxe5+ ) 31.Bxe5 1-0

————————————

Ivkov Borislav –Lengyel Levente : 32.Rxc5!  Decisive 32… Nxc5 33.Bb4! Qc7 (33…Rc8 is met with 34.Nd6)  34.Bxc5+ Qxc5 (Desperate. But after 34…Kg8. 35.b4 White simply consolidates his winning advantage.  35.Qxg7+ Ke8 36.Qg8+ Qf8 37.Ng7+ Kd7 38.Qd5+ Ke7 39.Nf5+ (Good enough, but 39.Qb7+ is forced mate in 11 moves!  1-0

Pietzsch Wolfgang –Novak Ivan: 40.Qxf7!! Qxf7 41.Rd8  The whole point. White wins atleast a piece: 41… Qg8 42.Rxg8 KxR 43.BxN etc   Black rightly threw in the towel after 41.Rd8 1-0

Saiyn, Zhanat–Velten, Paul:  28.Rxg7+! Nxg7 29.Nf6+ Qxf6?! Desperate, but after 29…Kf8 30.Nxd5 Black should lose in the long run: taking the Knight allows White to get a Bishop ending a pawn up; moving the Queen allows 31.NxB with a huge positional advantage.  The game continued:  30.Bxf6 Nh5 31.Be5 and White had no problem winning.

Asgarizadeh, Ahmad–Du Plessis, Heinco:   21.Ba3!! leaves Black defenceless  If 21… fxe5 ( 21…Qxa3 22.Qxf6#  or 21…Bxe5 22.Bxe7 Bxf423.Bxf6# ) 22.Qh6 etc  Black could throw in the towel with a clear conscience.

Wang, Richard–Yuksel, Atilla Koksal:  29.Ba3! Qg7 30.Be7!! beautiful 30… Bxe5  31.dxe5 1-0

Lozhnikov, Vyacheslav–Zhanbai Uulu, Zhokhar:  25.Rxc5! Qa7 26.Rcxe5! 1-0  Too much is too much!

Carneiro, Vitor Roberto Castro—Zor, Alber Kadir:  25.Re6+! Re7 (The Rook can not be taken because of 26.Rf8+!!) and now the best is to exchange both pieces on e7 and then play Bf3!,
