00:00But our problem is that a part of threatening to our rooks,
00:06black queen also threatens mate, mate in one,
00:09because pawn on a4, you know, creates these mating threats.
00:13So what to do?
00:15There's only one way to escape from all the threats,
00:18is to create a bigger threat.
00:20In our case, it's a check.
00:22Rook h2, check.
00:24By giving a check, we force our opponent to move the king.
00:29So nothing else can happen.
00:31So the king moves on d1,
00:33and now there's still two threats, you know,
00:35taking the rook on a8 and mate on b3.
00:38We take this pawn by just, you know, eliminating both threats.
00:42Again, our rook escapes and takes the pawn,
00:45and there's no more mate here.
00:48It seems for a moment that we could be in danger
00:50because black makes another double attack.
00:54Queen from d5 goes to d6.
00:56Remember, queen could attack on both sides of the board.
01:00Queen d6 is check, but also rook is hanging now.
01:03But now we use the power of our rooks.
01:05We protect against this check.
01:07Rook goes on b4.
01:08And if black loses its guard and it grabs the rook,
01:19then suddenly, you know, we use a new theme that we'll learn later.
01:24It's a skewer.
01:25We give a check.
01:27King moves to the second rank, and then another check.
01:30And now you see black's king and black's queen,
01:34and then the same line, the same row, and we're winning the queen.
01:38So that's why, you know, black in this situation should be cautious
01:42and just keep checking, you know, accepting draw as an inevitable result.
01:47So even for very strong players, it's sometimes very challenging
01:53to actually look at your own tactics, but also to be on guard about opponent tactics.
01:58That's one of the key tests.
