00:00Our king, forget about this pawn, it's already on h3, it's too close, but we go on e6, and our pawn now is protected, and our pawn will advance as well.
00:10Of course, black can try to win this pawn first, king b6, but then our king continues his journey, keeping an eye on two directions, king e5,
00:20and now if black takes this pawn, then our king is in the square, so that's where it can stop the advance of enemy's pawn,
00:30and if pawn goes on h3, then we change the direction.
00:35There were so many studies followed this famous rated position, and it all seems simple now,
00:42but I can tell you that when it was first invented and demonstrated, people couldn't believe their eyes.
00:47They were just learning about unlimited opportunities that could be offered by chess geometry.
01:01We can look at another position.
01:04Similar ideas, more complicated, and the study is a little bit less famous than rating.
01:17white pawn is on c7, just also one square from promotion.
01:26But promoting pawn doesn't help, because black gives a check, bishop comes in the game, king c7, bishop takes the queen,
01:35protecting the pawn, and after we take the bishop, black pawn is unstoppable.
01:40So what we can do?
01:46Can we try to prevent black bishop from appearing on f5?
01:52Doesn't work, because then black king comes close, and bishop still goes on f5.
