Award of 34th TT Chess Composition Microweb C 4.4.2014

(preliminary award by Sven Trommler)

The 34th TT Chess Composition Microweb required fairy selfmates with at least two antibattery mates.

I received 12 anonymous selfmates in 2 .. 7 moves.

The level of the tournament wasn't very high. The following problems I excluded because they were not rich enough in content: No. 34-01 (Ka1/Kh7) (Also there are some weaknesses in construction, e.g. RLa8 to a7, -bBb8), 34-05 (Ke8/Kd4), 34-06 (Kh8/Kf7), 34-12 (Ka1/Ke4).

No. 34-02 (Ke5/Kh3) didn't meet my acceptance because there was no harmony in the conglomerate of nocapture and fairy pieces (locuste, black supertransmuting king and grasshoppers).

Because there were no problems of sufficiently high quality, I did not decide to award a prize.

Many thanks to Juraj Lörinc for the good collaboration and congratulations to the honoured composers.

1...Gf8 2.Sf7+ Ke6 3.Sd8+ Gxd8(Gd1)#
1...Gd2 2.Sf3+ Ke6 3.Sd4+ Gxd4(Gd1)#

The time-hounored Siers-battery in an Anticirce selfmate! We find the Siers-Battery five times, once in the threat and four times in variants. All four moves of the bGd8 refute the threat and require another way of the w knight.

I decided not to give a prize because the first white move is obvious (It vacates the fields c1 and e6.) and the Anticirce condition is only used in the last black move.

s#3 (14+5)
Anticirce type Calvet
1+0 grasshopper, 1+1 rook lion

1.PAb5? th. 2.Qf4+ Sxf4(Sb8)#
1...NAxb5(NAb1) 2.Qg5+ Kxg5(Ke8)#

1.VAb5! th. 2.Qg5+ Kxg5(Ke8)#
1...NAxb5(NAb1) 2.Qf4+ Sxf4(Sb8)#

The first problem with Le Grand theme. The Anticirce-effects are interesting, e.g. the play of wPao/ wVao to b8 and e8 and the construction bPaoa8-wKg8-bRh8.

Additionally we find a Pao/Vao-Grimshaw on b5 in order to realize the Le Grand mechanism.

The refutation of try is less typical for Anticirce.

s#2 (7+11)
Anticirce type Cheylan
2+1 pao, 1+0 vao, 0+1 nao

1.RLd2! th. 2.f8B+ BLc1#
1...e3 2.Sb5+ BLg1#

I like the Anticirce-effects on c1 and g1 in order to realize the Le Grand theme. However the use of white rook-lion a2 is not satisfying. It is only a hurdle for the black bishop-lions.

s#2 (6+6)
Anticirce type Calvet
1+1 rook lion, 0+2 bishop lion

1...Kh2 b 2.g3+ B Kc2=G 3.NHe2 Gd3#

We find changed continuations after 1...Kg1 and 1...Kh2. Also there is some additional synthetics between different moves; but in my opinion the balance between the use of fairy pieces/ fairy condition and content isn't satisfactory.

1...f5 2.Ba4+ K3h5#
1...f6 2.Sa4+ K3h6#

A nice idea with a rare fairy piece. Also the tries are convincing. But because the fairy piece needs three hurdles the play looks clumsy.

s#2 (13+8)
2+3 kangaroo with 3 hurdles

The advantage of this five-man problem is the try. But such "puzzles" are not to my taste.

s#7* (2+3)
1+0 zebra, 0+2 nonstop equihopper

Three variations by the play of black king and white nightrider lions. The play is a little bit symmetric.

3+3 lion, royal nightrider lion d4
supertransmuting king a1, 2+0 nightrider lion
