White to play and mate Black

Fuchs v unknown, Wilhelm-Pleck-Stadt 1980

Solution

Fairly easy, because there are very few “forcing moves” to examine, or, as Purdy says, “examine all biffs“.

1 Rf5! 1-0

Depending on how Black captures, 2 Re7+ 2 Qg7+ 2 Bh5+ follow, winning

White to play and mate Black

Braga v Rossetto, Argentina 1980

Solution

Again, not too hard today: check, check, check, check, check, check, check, mate: nearly all forced.

1 Nf6+ Kh8 2 Qh6+ Bh6 3 Rh6+ Kg7 4 Rh7+ Kf8 5 Rh8+ Kg7 6 Rg8+ Kh6

7 Nf7+ Rf7 8 g5mate.

White to play and mate Black

Garcia P v John Van der Wiel, Kastrikjum 1980

Solution

Not too hard today: 1 Rf5! is a natural try, threatening to capture on f8, or if 1…ef or 1…gf, 2 Qe5+ and mate. And if 1…Re2, then 2 Rf8+ and 3 Rg8mate.

So 1…Rf5 when 2 Qe5+! all the same, and if 2…Re5 3 Bf6 mate.

White to play and mate Black

Kurho v Horhamer, Helsinki 1980

Solution

1 Bf5! was my solution, since the Pe6 is tied to the Pd5 (1..ef 2 Nd5 and it is all over); if 1…Rg8 (since 2 Bg6 3 Qh8+ was threatened) then 2Bg6 Rg6 3 Qh8+ and 4 Qf8 1-0.

The game continuation was 1 Rb7, with a similar idea: if 1…Bb7, 2 Be6 breaks through.

Black to play and mate White

Escott v Arkell, Birmingham 1980

Solution

Easy today: 1…Qb4 is obvious, it being a puzzle. 2 ab[] Ra1+ 3 Qb1[] Rb1+ 4 Kb1[] Be4+

5 Ka2 Bc2! 0-1 or 5 Kc1 Ra8 and Ra1 0-1.

Black to play and mate White

Huss v Korchnoi, Biel 1979

Solution

Like yesterday’s puzzle, this took me a while, but was satisfying to solve.

1…Ra1+ 2 Rb1 (2 Ne1 Ne4) Qe4! is a double attack, and ‘the point’. The rest is just checking how to conclude the game.

3 Ra1 Qe2+ 4 Kg1 Ne4 and 1-0; if 5 Rf1 as played, 5…Bd4 concludes; or 5 Qa7, 5…Ba1.

White to play and mate Black

Larsen v Strauss, Lone Pine 1979

Solution

This puzzle took me a while, partly because I followed by habit of “if at first a line fails, try it again; and again”. I tried to make 1 Rh5+ work, but couldn’t, because it doesn’t- Black wins.

My engine tells me that 1 Rh7 wins: 1….Re4 2 Kh2 Rh4 3 Rg3+; or the cute but totally inhuman 2…Rf4

3 g4!!! Rf3 (Bf3 Rh5 mate) 4 Bf3  Bf3? (4…Kf4 1-0) 5 Kg3!!; but 1 Rh7 isn’t the best move, and after a lot of looking again and again at 1 Rh5??, I found 1 Rff4! and it is all over.

1…ef? 2 Rh5 is mate, and in the game Black played the better 1…g5 but Bent found 2 g3, when Black resigned.

White to play and mate Black

Vaisman v Stefanov, Rumania, 1979
Solution 
Again, as 471, Easy but difficult, in Jacob Aagaard’s terminology. 

1 Qf6!! is obvious, and probably doesn’t deserve the exclamation marks I have given it. 
1…gf[] 2 Bf6+ Bg7[]

and now the key move, 3 Rd7!!, after which everything falls into place. The main point is 3…Bf6 4 Rh7 mate. 3 Rd7!! does deserve the exclamation marks,

If 3…Qe5, then 4 Nf7+ forking the king and queen wins easily.

White to play and mate Black

Perenyi v Barczay, Hungary 1979
Solution
I think I have seen this position before, and therefore ‘knew’ the solution. I don’t recall where I saw it, but I think it was in an obit/appreciation of Perenyi. I may have listened to this, for instance, and then done some of my own research into this player. Googling to finish this posting found many things of interest, including this.

 
1 Qd7+! or 1 Rc8+! are equivalent. I chose the latter, and after 1…Ke7[] 2 Qd7+

Then it is check, check, check, check…bringing the Rh1 into the hunt too, so that it is 4 white pieces attacking the black king, who has no defenders: like jackals descending on their prey. Black has one of two alternative defences, all of which are treated in similar check, check, check manner, so I will only show the diagrams for one hunt.

He can’t get away ‘the other way’ either:
