The hall(s) of the events will be inside the hotel. The hotel is only 20 min. drive from the center of Athens and Piraeus and 25 km away from the Athens international airport “Eleftherios Venizelos”, which is very well accessed by public transportation or taxi. Parking space is available in front of the hotel.

The Express Bus X96 departs right outside the arrival level of the Main Terminal Building at the Exit 4 of the airport. There are only one-way tickets and cost 5 €. Tickets are available from the bus drivers or from the ticket kiosk at the bus departure area. Express Bus X96 runs 24 hours every 20-30 minutes. The bus needs 35-45 minutes to reach the hotel. The bus stop that you will get off is called "4th station of Glyfada". The hotel is located just next to the bus stop.

Theme Elmgren

(Initial date of this post was 21/12/2015)

In this post we will see the Theme Elmgren under a different light. This theme is named after the Swedish composer Bertil Elmgren, born 25/05/1912.

In this theme, all the black pieces (3 or more), with a possible exception of the bK, are actively refuting white tries!
A try is an attempt by the White to win, but the Black has a unique defense.
The White has at least three such tries, and all the black pieces take their turn to refute.
With more black pieces on board, the probability all of them refuting a try diminishes, making it more difficult for the composer to achieve an Elmgren.
Likewise, the more the black pieces, the more are the tries, making the problem relatively more difficult for a solver.

Having all the black pieces struggling in defense, symbolizes a common battle where no one stays behind the trenches, waiting to see what will happen!
There are no idle pieces, simply blocking a flight or stopping an unwanted second solution.
Everything is useful and active!

I have published in this blog some problems containing the Elmgren theme.

We shall see now some rare compositions with theme Elmgren, with at least five black pieces refuting white tries.

5 black pieces

6 black pieces


Problem-810
Manolas Emmanuel (GRE)
original
dedicated to Kostas Prentos


rB6/1sK1S2P/2P2p2/1R1Pk1P1/6R1/1B4P1/6bQ/6r1 (12 + 6)
#2

Tries: {1.Sg6+? Kf5!}, {1.Bc2? [2.Sg6#] Sc5! (The square d5 is guarded by three white pieces Rb5 Bb3 Se7. One leaves making the try-move, one will leave to make mate, so the Black shuts off the third guardian : Theme Zappas simple)}, {1.d6+? Sc5!}, {1.Re4+? Kxe4!}, {1.Kxb7+?/Kd7+? Rxb8+!}, {1.Qxg1? [2.Qd4#] Be4!}, {1.Qxg2? [2.Re4#/Qb2#/Qe2#/Qe4#] Rxg2!}, {1.Qh6?/h8=Q?/h8=B? Rf1!}, {1.h8=S? [2.Shg6#/Sf7#] fxg5!}.

Key: 1.Rf4! [2.Sg6#]
1...Be4 2.Qb2#, 1...Bxd5 2.Qe2# (horizontal-diagonal transformation)

Theme Elmgren (here the bK is also refuting tries). In the phases {1.h8=S?} and {1.Rf4!} there is Anti-Dual with moves Be4 and Bxd5. (There are some more technical merits to examine: changed mates in two phases, a pin-mate, Urania, Bartolovic, Dombrovskis paradox, Anti-reversal, Anti reversal-menace).

Theme Elmgren. Multiple captures of the bQf6. 




Upgrade on 12-01-2016

Motivated by this post, the Italian composer Alberto Armeni decided to compose a problem with more than 6 black pieces, all refuting tries. He has initially set the record to 8 pieces, which we were glad to present here, but then he created a task with 11 pieces (see Problem-814 below).
