Daily chess puzzle: Check Mate #351

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

 

Black to play and mate White

3511

Nevole v Gonszor, 1970

Solution

I chose 1…Rd2! which Komodo gives as -11; but Komodo gives slightly higher to the move played in the game, 1..Rb5!: 2 Qb5 Bd4.

I also tried to make 1…h4 work, but it doesn’t: the engine’s assessment plummets to 0.0.

Daily chess puzzle

A break for a day from Dragoslav Andric’s 1981 book “Matni Udar”.

A special puzzle on my birthday (the only thing I share with Donald Trump)

Instead, a puzzle I really struggled with from Jon Speelman’s Agony Column on Chessbase.

White to play and find a strong continuation

speelman1

Hiban v Harley, 2016, shown on Chessbase.com

Solution

I would never have found the combination in a game, and neither did White. As it was, something about the puzzle intrigued and interested me, and I spent a lot of time on it, culminating in setting up the pieces on one of my big sets, carrying on studying it, then resorting to moving the pieces round. Then giving up, and, as I gave up, finding the solution. That is how it is sometimes, isn’t it?- the answer comes from nowhere.

1 Nd5! Nd5 2 Nb5!!

speelman2

White wins at least a pawn.

That’s the only line Jon gives, but I worried more about 1..Qb7, after which I found (eventually) 2 Qa5! which Komodo tells me is +2: as I saw, the bind is really strong.

However, Komodo finds 2 Ne7!!

2…Ke7[] 3 Ne6!!

speelman5

A truly ridiculously good computer line. 3…Qb8 (or 3…Qc6) 4 Ng7 takes the LPDO Bg7. The tactics continue to roll. The line I looked at was 4…Rg8 (trying to capture the Ng7) 5 Bf4 (hitting d6) 5…Ne5 (blocking the bishop) 6 Be5! (intending to…) 6..de 7 Qb4+ (the point of Be5)

Daily chess puzzle: Check Mate #350

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

 

White to play and mate Black

3501

Csom v Ghitescu, Siegen 1970

 

Solution

Either of two moves wins: 1 Be7 and 1Ne8+ followed by 2 Be7: the N is tied to defending d8, and so the Bishop can’t be captured.

I prefer 1 Ne8+, since there are then fewer variations.

Daily chess puzzle: Check Mate #349

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

 

White to play and mate Black

3491

Toljcov v Mojsejev, 1970

Solution

Nice, but it is a motif I have seen before; though I don’t think I have seen the actual position before.

1 Ng5+! hg 2 Rh3+ Kg6[]

3492

3 Rh6+! and if 3…gh, 4 Qg8 mate, so 3…Kh6, when 4 Qh8+ Kg6[] 5 Qg6 mate.

Daily chess puzzle: Check Mate #348

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

 

White to play and win

3481

Dukic v Tomasevic, 1969

 

Solution

Quite an unusual, and pretty way to win: 1 Qg8! hits the LPDO Rh7, and exploits the fact that the Rd8 is tied to the Nd7, because the Black king is in a net. The words in bold are all CJS Purdy’s language.

Black is forced to play 1…Rf7, when exchanging twice on d7 wins the rook.

3482

Black doesn’t have a perpetual, so White will consolidate and win.

Daily chess puzzle: Check Mate #347

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

 

Black to play and mate White

3471

Vasiukov v Damjanovic, Amsterdam 1969

Solution

Black missed the idea in the game, but since it is a puzzle from a book, it is none too hard.

1…Rh3+! deflects the King to h3, when 2…Qg4+! mates in a couple of moves. In the game, Black won more prosaically.

Daily chess puzzle

A day’s break from the daily posting from “Matni Udar”, to give a puzzle from one of my 3-0 blitz games.

Black to play and win

Estebandel

“Estebandel” vs allanbeard, Chess.com, 3-0 blitz, 22/4/17  {posted now because I draft blogs week’s ahead, especially when, as recently, we have a holiday period, before which I need to get ahead}

Solution

I was pleased to find 1..Rd1+! 2 Rd1[] Nf2!, and even more pleased to see that, when drafting this blog, Komodo 10 approves.

Estebandel2

All the pieces are in the “right position” for the combination to work. If 3 Kf2, 3…Ng4+ discovers on the LPDO Bf4, and also on the Qc3 (which had just moved from d2 in the puzzle diagram position).

Quite satisfying.
