00:00of putting more pressure on this knight.
00:02So that's why all we need is just to make an intermediate check, rook e2.
00:08We're attacking the king, and if king runs on d4, then we do a fork.
00:12Remember?
00:13Fork.
00:15Double attack, king and rook, winning the material.
00:18And if king goes on f5, then we'll go rook e3, and then we'll win because of the pin.
00:23Black has no way without sacrificing an exchange and having a totally lost endgame.
00:28So it's important, just another important thing, intermediate move.
00:35Often happens.
00:36You can easily miss it because, you know, you look at moves like rook f3 to create immediate threat,
00:43but actually rook e2 wins because it destroys black's coordination, so pushes the king.
00:51So that's also quite a useful example.
00:54Very few pieces left, but I think it's quite instructional.
01:06Let's have a look at this position.
01:11White has material advantage.
01:13It has, you may say, extra piece because queen is roughly equal to two rooks, but white has an extra bishop.
01:20But the problem is that this bishop is pinned, and it's an absolute pin because there's a king there,
01:27and black's preparing to go rook c1 just to have a second rook attacking this bishop.
01:33And by the way, there's potentially there will be another attack from there.
01:37But no matter what, you know, if black rook shows on c1, it's an exchange on f1.
01:43Black recovers the piece, and it's at best for white will be drawn.
01:47Technically, white can go c6 by trying to bring the, for instance, bishop e6, bishop e3,
01:56trying to bring bishop back to protect c1 square.
01:58But, uh...
02:00But, uh...
02:00But, uh...
