Multiple thematic tries, with the play in each differentiated from the others by clever tactics; multiple echoes too. This is a fine study in any context, but in this particular theme tournament it is outstanding, displaying the theme to maximum advantage. Rook studies tend to have difficult, if not obscure, supporting variations that are not to everyone’s taste. However, one cannot but be impressed by the variety of play following the three moves of the  black Kh6 in reply to 1 Re6+. (GBR)  The basic known matrix has been elaborated with multiple 'thematic' tries. The important and interesting one shows knight annihilation by white to open a line for his rook. (ISR)  In total 6 positions A/B with minor differences. White has two main defences against the promotion of the h-pawn: either by playing Rb8 threatening Rh8+,which only works if the BK is on the h-file (A5/B5), but not too close to the 8th line (A1/B1) and if there is no WS on b5 (A3/B3). The other defence is playing Rxg1+ followed by a knight fork. This only works if BK is at g5 (A2/B2 and A4/B4). As a bonus there are positions A6/B6 where White only draws the rook ending if the BK now is as far off as possible. All this is accomplished by subtle checks (1.Re6+, 1...Kh7 2.Re7+), and a surprising sacrifice (3.Sa7!) in the 1...Kh5 main line, which turns out to be the thematic try in the 1...Kg5 main line. It takes some time to comprehend the study, but all lines are crystal clear. A thematic masterpiece.

Bxg6 {position A1} {An economical pendulum play, in which the black h-pawn is forced to move and to unguard the square g6. (FIN)  White must wait until the black pawn on h7 moves to h5 (A1/B1), but not to h4 (A2/B2). The play looks a little bit too mechanical and analytic. (GER)  This shows a complex zugzwang at move 9, and it seemsto be reciprocal zz, which is not allowed by the Theme. We nonetheless allow this study, because there are some differences in the play between the solution line and the tries. The play is interesting and the way White controls the black queen particularly so. There is a nonhuman feel to it – the justification of many of the moves is only comprehensible with extensive analysis. After 3 Rxb2+, there are seven men on the board for the capture-less main line all the way to move 18. What White does is invoke a virtual zugzwang by engineering a mating net, so Black ‘succumbs’ by advancing the onlooker pawn on h7 that is standing idle in the wings. That most insignificant chessman, the h7-pawn, decides the outcome. (GBR)  White loses a move to force …h5 which removes a future protection from the black queen. The RBB-Q domination is impressive and the economy is excellent. (ISR)  Interesting idea. For position A1/B1 White maneuvers to force black to put his h-pawn at an unfavorable square. This is echoed in A2/B2 with the difference that White should not perform this maneuver as black then puts his h-pawn at a favorable square.

The black rook has to move to h8 (instead of c8) in order to complete the nice pin model mate with selfblock on h8. (GER)  Exciting play, culminating in a mating finish and preceded by White sacrificing both his advanced pawns merely to clear the c7 square and then force Black to re-block the h8 square. The A3/B3 pair is not thematic, having two differences, but the A2/B2 pair is thematic and is also central to the study. Particularly appealing is the fact that White dispenses with the two pawns which seem to embody his winning chances. (GBR)  White checks the black king all the way to a mate withtwo active selfblocks. The general economy is good, but the thematic component is average and the black pieces hardly play, which make it feel more like a direct mate than a study. (ISR)  Three critical positions with very different points: A2/B2 with the bRh8 as a selfblock in a mate, A3/B3 with a WPc7 blocking a square for a fork, and A3/B3 with the WS or e7 or b6. The crucial difference between A1 and B1 is shown after 6…Qf1+ 7.Kxf1 Rxh8 8.Kg2 (WSe7), while in the thematic try 4...Qf1+ 5.Kxf1 Rxh8 6.Kg2 (WSb6) Black plays 6...axb6.But there is a cook in the line 6...Qf1+: also 8.Sg6 or 8.Rf2 win. So one thematic position (A1/B1) is lost. Otherwise a very good study when we only consider A2/B2.

Qa8+ $1 {A clear-cut solution and the try is beautifully shown. (FIN)  Amusing trip of the white king across the board in order to open the long diagonal. However a very forced play. (GER)  A fine work throughout. 1 Rd5+ is unexpected, allowing the eventual king-fork of the two white rooks; the white king marches to the queenside just to force the apparently-irrelevant move …b6+, and then marches all the way to the h-file. The reason for forcing the move …b6+ is only revealed on the last move of the solution. That forcing of Black to play b7-b6+ opens the a8-h1 diagonal. Long-range foresight sets up a long-range skewer.  The claimed anticipation by Rossi is a marginal anticipation at most. (GBR)  Foresight to open a diagonal has been accomplished even in pawn studies (Rossi 1961). Here the foresight distance is extended at the cost of three rooks, a bishop and two pawns. (ISR)  Excellent thematics. White forces black to open the a8-h1 diagonal for a queen skewer 14 moves later. Further merits are: a long WK march from kingside to queenside and back, and a remarkable BK forking two rooks.

Every man has a critical role in this quite game-like position with play over the whole chessboard. Tightrope play strung between an otb Master Class and thematic artistry… somehow getting away with it! Only at move 9 do we enter tablebase territory. (GBR)  In the solution 12...e5 appears at the end and allows an immediate winning en-passant capture. In the try the move order is different and 8...e5 happens 4 moves earlier, so by move 12 white's en-passant opportunity is long gone.

Fully thematic, with the apparently trivial difference in the a-pawn position being what allows a mate. The ‘anticipation’ in Claims seems tous irrelevant. Neatness upon neatness. Pelion on Ossa. The very unexpected reciprocal zugzwang is acceptable  because it is not thematic. (GBR)  White wastes a move with his queen, so he does not have to move his pawn, which would lead to mate. Highly original. (ISR)  Excellent thematic study with apparently small difference between the move of the solution and the TT. The central idea is a zz, which forces WTM to advance a pawn, which is an active self-block in the stalemate. The fact that the mate in the try is anticipated (see Claims) is not very relevant indeed (replies) as there is no such active self-block.

The logical content in A2/B2 is not clear. (GER)  This is a good example of a study where BTM is justified. The Foresight Theme is shown at great depth – White’s choice at move 2 is justified at moves 13 and 16, and the reason is most unexpected. The play is somewhat ‘database-ish’, but doesn’t go beyond comprehension at any stage. The study is devoid of sacrifice or embellishment, but is an outstanding example of the WCCT10 Theme. If Magnus Carlsen were to annotate and comment the play, wherewould he place exclamation marks?(GBR)  Pretty setting, active play, and great foresight to avoid a future obstruction on e7. The try is slightly less natural than the solution but one must respect what is possible. A high quality study. (ISR)  Distinct point A1/B1: the WK must leave square e7 unblocked for the WB.

(FIN)  A logical sacrifice of the WPg4 in order to create a stalemate only 17 moves later. Unfortunately there are too many captures; in particular 2.f5xSg6 is a real weakness. (GER)  Confusing initial position, but necessary to set upthe complex tactics that are the heart of this study. The foresight is long-distance. The stalemate finishrounds it off in good style.  In the diagram, the white king is already stalemated, but this is an illusion, shattered as an artillery battery’s barrage is met by a counter-barrage, making nonsense of barbed wire. All hell is letloose. When the smoke of battle clears, the white king emerges into no-man’s-land until a surprise Armistice is declared. (GBR)  Another early pawn sacrifice, this time for stalemateavoidance. The play is refreshingly double-edged with interesting moments like the knights dance on moves 4-8 and even a knight promotion. The 10 non-thematic captures are a lot, but they are spread over 18 moves. (ISR)  Surprising key, featuring active removal of WPg4, so that no less than 18 moves later, white is stalemated. Capturing the passive BSg6 is a drawback, the S-promotion a bonus.

In both instances the move choice (2.Re1+! 12.Kc5!) is not so obvious. As an extra the composer gave 1.Bf2? as a thematic try, but this rather distracts from his great idea.

Мартин, с победой! В чемпионате было несколько отличных этюдов. И я рад, что победил один из них. Было бы печально, если бы первым стал компьютерный этюд 012.

Судьи оценили этюды следующими баллами:

Финны судили отчаянно – одних обожают всей душой, других искренне ненавидят. Немцы судили сдержанно, раздав всем этюдам от 2.6 до 3 баллов. Самое бездарное и черствое судейство в чемпионате. Британцы считали звездочки в этюдах (то есть, непонятно что), не обращая внимания на идеи и мастерство. Израильтяне считали объем вариантов. Необычное их привлекает больше, чем качественное. А голландцы искали эмоцию и масштаб.
