The new type of chess compositions
& the celebration of the 21^st year of Bruno’s chess problem daily

Dear visitors of ‘Bruno’s Chess Problem of the Day’ website! Several months ago you and I have congratulated very warmly dear Bruno Berenguer with 20 years of his chess problem daily! His noble, titanic work was started in the 16^th of October, 2000, so his chess composition daily became the FIRST such daily in the whole world! Now we have the 21^st century, the year 2021 and the 21^st year of this daily!

Although this website is the oldest alive chess puzzle daily website, it is a little younger than this start, and Bruno Berenguer’s work was continued very successfully here. Its fame has always been grown, although the 21^st century created later an ocean of chess puzzle daily resources which have the common one “oldest father”.

Dear Bruno! I’m extremely thankful, and I wish a further prosperity to ‘Bruno’s Chess Problem of the Day’ for a lot of years!

Here are my chess problem presents. Thus, I have invented some chess compositions (chess problems) of a new type, which is my invented type. It can be named as ‘Requirements-Let-Win’ (‘RLW-compositions’). These compositions reflect chess opening theory and traps.

Chess composition no.1.

Its position for solving is my invented theoretical position of the Jerome gambit, where my new opening idea is marked by ‘AN’ (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bf7? Kf7 5.Ne5 Ne5 6.Qh5 Kf8 7.Qe5 d6 8.Qg3 Nf6 9.b4 AN Bb4 10.Bb2 Qe8), and its question is: “What is White’s next move, which can lead to White’s win if Black is submitted to the two requirements?” These requirements are the following (the term ‘a blunder’ is about chess theory which knows no requirement):

1. Always, except after a possible blunder, Black chooses the move only, which makes Black’s material advantage in the moment of this move maximum, without a decrease of Black’s true material advantage*.
2. Always Black makes a capture if in result Black can’t lose by mate immediately.

[*Comment about the term ‘a true material advantage’: If Black captures some material and White captures an equal material immediately after it, then it’s an exchange of an equal material so Black receives no true material advantage, but only a material advantage in the moment of Black’s move.]

Here is its solution. White’s winning move is 11.0-0! Qe4 (the capture 11…Ne4 is impossible: 12.Qg7#) 12.Nc3! Bc3 13.Bc3! Qc2 14.Rac1! Qa2 15.Bf6! gf (15…Qf7 16.Bd8!, and White has enough advantage to win) 16.Rc7!, and White wins. (It should be added that it’s very easily to find the further White’s moves: 16…Qg8 17.Qd6; 16…Qe6 17.Qg7 etc.)

[Here are my analytical notes about a usual game (it can be played):

1. Note to 12…Bc3. In a usual game the response 12…Qc2 is possible and is better.
2. Note to 13…Qc2. In a usual game this move isn’t good, although it isn’t a blunder: even after the best response 14.Rac1! Black keeps enough advantage there.
3. Note to 14…Qa2. In a usual game this move is a 1st Black’s blunder, which transforms Black’s won position into a lost position.]

Chess composition no.2.

Its position for solving is a well-known theoretical position of the Jerome gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bf7? Kf7 5.Ne5 Ne5 6.Qh5 Ke6 7.Qf5 Kd6 8.f4 Qh4), and its question is: “What is White’s next move, which can lead to White’s win if Black is submitted to the two requirements?” These requirements are the following (the term ‘a very strong move’ is about chess theory which knows no requirement):

1. During the whole opening stage (WOS) Black chooses the very strong move only, which makes Black’s true material advantage maximum, can’t make Black’s piece unprotected at once or as a result of a forced sequence of moves and can’t make it captured.
2. After the end of WOS Black accepts White’s “Wing gambit”.

Here is its solution. 9.g3! Qf6 (on another way - 9…Qe7 - White wins after the same moves; the ways 9…Nf3 10.Kf1 Qh6 11.Qd5 Ke7 and 10…Ne7 11.e5 Kc6 12.Qe4 d5 are impossible in this solution, because they make Black’s piece unprotected) 10.fe! Qe5 11.Qe5! Ke5 (it’s an end of the opening stage; after 10.Qe5? Qe5 11.fe Black must not play 11…Ke5?, because 11.fe is already an end of the opening stage here) 12.b4! Bb4 13.Bb2! and then 14.Bg7!. White wins.

[Here is my analytical note about a usual game (it can be played):

1. Note to 12…Bb4. In a usual game this move is a 1st Black’s blunder, which transforms Black’s won position into a lost position. (This blunder creates the theoretical position of the Bona fide master attack as a result of its moves’ transposition: this White’s attack is my invention, its analysis was published in 2020, August 24, on Rick Kennedy’s blog on the Jerome gambit).]

It’s very important that in these initial positions Black has a very large advantage in usual games and that Black makes then only one blunder on each possible way of these usual games, if these games and these solutions are the same: it should be considered as the common property of all possible compositions of this new type. Moreover, there are three Black’s moves between the initial position and the blunder on one way (or more) of each game, and this number should be considered as a recommended minimum for this type.
