Position from Part 2: Anatoly Kuznetsov/Boris Sacharov 1958.
White to move and win.

This is the beginning of the study, the puzzle I gave last time was after move 1. 

Solution: 1.Nc6! (1.Bf6? Nd4+) 1...g1Q (1...Nd4+ 2.Nxd4 g1Q 3.Nb3+ Ka2 4.Nc1+ Ka1 5.Bf6+ Qd4 6.Bxd4#) 2.Bf6+ Nd4+!! 3.Bxd4+ Qxd4 4.Rxh1+ (4.Nxd4? Be4+) 4...Ka2 And here comes the star move:  5.Ra1+!! Kxa1 (5...Qxa1 6.Nb4#) 6.Nxd4 From here, we use our knowledge of Stamma’s mate. 6…Ka2 (6…a2 7.Nb3#) 7.Ne2 Ka1 8.Nc1 a2 9.Nb3#

Another intriguing checkmate is Lollis' mate, named after the Italian player and writer Giambattista Lolli (1698-1769). The checkmate involves infiltrating Black’s fianchetto position using pawn and queen. Often the pawn is on f6 and the queen lands on g7 to checkmate the king via the h6-square. The following example is a case in point:

 

Domenico Ponziani 1782: White to move and win.

This is the earliest example of Lolli's mate that I have been able to find. There is a flaw in the study as the solution shows:

1.f6 g6 (Other moves lead to immediate disaster on the dark squares: 1...Qf8 2.fxg7+ Qxg7 3.Qd8+ Qg8 4.Bb2+ f6 5.Bxf6# or 1...gxf6 2.Qxf6+ Kg8 3.Bh6+–) 2.Qh6 Qg8? (Here is the flaw: 2…g5+! 3.Qxg5 Qg8 and Black saves himself and is better) 

3.Kg5! (3.Bf4? again allows 3...g5+!) 3...b4 4.Bf4 (Black is completely helpless in the face of the bishop transfer to f8.) 4...b3 5.Bd6 b2 6.Bf8 b1Q 7.Bg7+ Qxg7 8.Qxg7# 1–0

I haven’t been able to find Lolli’s checkmate by Lolli himself, not even in his most famous work from 1763 (in English: “Theoretical-practical views on the game of chess”). Other sources could produce no such mate either. So, I will have to conclude that the naming of this checkmate is of the previously mentioned “false notion of legacy”: It was named after him because he was deemed a great player or writer.

Here is a puzzle from the above-mentioned work by Lolli that comes the closest to a Lolli mate setup. Solution plus other details will follow next time.
