{This is one of my earlier efforts and a personal favourite. How does White win a titanic battle to secure promotion?} 1. b7 Bc5 $1 {A surprising defensive resource to open up the eighth rank, whereas all the rook's direct attempts to get there are instantly refuted.} (1... Re6 {loses to} 2. Nc7 $1) ( {while} 1... Rc6 2. b8=N+ $1 { catches the rook to obtain a decisive material advantage.}) ( { The alternative is not any better:} 1... Ra6+ 2. Ba7 { and the promotion is unavoidable.}) 2. Bxc5 (2. b8=Q $2 { loses the newborn queen after} Ra6+ 3. Kb7 Rb6+) (2. b8=N+ $2 Kc8 3. Bxc5 { is a theoretical draw. The simplest way for Black is} d4 {in order to give away the d-pawn. White will never be able to weave a mating net, as the black rook will threaten to sacrifice itself for the bishop, in order to leave White with a useless knight pair.}) 2... Rh8+ 3. Ka7 (3. b8=Q $2 {is met by} Rxb8+ 4. Kxb8 Kc6 {with a royal fork.}) 3... Kc6 {This not only forks the bishop and knight, but also threatens a pin along the seventh rank.} 4. Bd4 $1 { A vital switchback.} ( {Quite a few solvers fall here for} 4. Nd6 $2 Kxc5 5. Nc8 Rh7 {with an easy draw.}) 4... Rh7 (4... Rf8 {or any other move of the rook along the eighth rank allows White a vital tempo for} 5. Ka6 {followed by 6. Be5 to win the rook by promoting and then mate with a bishop and knight. After the text move Black is poised to eliminate the vital pawn. How on earth is White still winning?}) 5. Bg7 $3 { A brilliantly unexpected bishop sacrifice masks the pinning line.} Rxg7 { The rook has been lured just a single square from its previous position, making a vital difference after:} 6. Nd4+ Kd6 ({and} 6... Kc5 7. Ne6+) 7. Nf5+ {are deadly forks, while retreating to the seventh rank would unpin the b-pawn, allowing a triumphant promotion.} 1-0
