 {MM: This is an epic study, with a variety of good moves and an original zugzwang. The introduction is forced with Black to move. The finish lacks pointedness. SN: This begins like a grotesque monster. Two pawns waiting to promote with check and the rest of pieces thrown around the board (the pawn on a6 being particularly annoying). But then the study turns into a fascinating epic tale. Playing through the study one is in for a number of surprises. Having witness the zugzwang after 12. c5, one expects the study to end in some kind of prosaic fashion, but that is when the play becomes really fascinating with 15. Bf8, 17. c6!, 18...Qg7!} 1...

 {MM: I like it. A good flow with logical tries. SN: I love the idea of the eternal pin on the pawn (why didn't I find this idea myself?!), but the introduction (while containing many excellent moments like 3. Rc6!!)) is not thematically or logically linked to the finale. What are 2 rooks, a bishop and a knight doing in what is essentially a queen ending? In addition, the main idea can be expanded with further dance moves of the queens. I would certainly have preferred more focus on the idea compared to the introduction.} 1. Rf8 $1 ({Logical try :} 1.

 {MM: This is an amusing en passant trick, which has already been shown by Helmut Waelzel by in the 10th WCCT (HHDBVI #4576). In a logical try Whitea []s pawn is still on g2 before g2-g4 allowing Black to capture en passant fxg3. In the solution the pawn ends up on g3, so that Black cannot capture en passant after g3-g4. The exchange on d5 is a minus.} 1. Rg6+ $1 ({Thematic try-1:} 1. e5+ $2 Kf7 $1 2. Rg7+ Kf8 3. Rg8+ Kf7 4. Kb4+ Nd5+ 5. Bxd5+ {, but} Qxd5 $1 $11 ) 1... Kf7 2. Kb4+ $1 ({Logical try:} 2.

 {MM: The introduction is nicely connected with the finish. SN: A good logical study with the kind of natural position that tempts the solver to start solving. It is not easy to see that g5 is the dream square for the White king, but this becomes obvious on the very last move where is covers the rook on f4 and f5, saving the day.
