Now let's talk about another category of deflection called interference. Interference is a form of tactics that disrupts harmony of the opponent's position, and cuts communication lines between enemy's pieces. And let's have a look at the simple position where white literally cuts communication between opponent's pieces. It's an endgame where black temporarily has a decisive material advantage. As you can see, it's extra rook. If nothing happens, extra rook wins. But it's white to move. And white could start by attacking one rook, and also preventing rook giving a check on f4 square. And black should be aware of danger. And to sacrifice rook immediately, eliminating all the pawns, and we, moving it into drawish endgame. Because if black doesn't feel the danger, and tries to keep both rooks on the board, then you can guess the move-- f4. Can you imagine, literally cutting communication between two rooks? One king attacks two rooks. Doesn't happen very often. Rooks are powerful pieces, but this time king has its day. And if black king comes to rescue, and our rook from a8 gives the check, and it's over. Because black, he has to move. And one rook was lost. And if black takes here, then it's a lost endgame. Because white pawn will be unstoppable. So this simple example shows you the power of interference. But of course, it's not as simple when you have practical games. But as an important tool, it could work well, if you know how to combine it with other themes. Let's have a quick look. So what do we see? Black king is in trouble. But how our queen-- that's the piece that can checkmate this king-- get to this diagonal? Because it seems at first sight that black queen protects this d5-square and protects this f7-square. That it protects both squares. But what if we use one of our pieces named the rook for interference and deflection? Beautiful move. Rook just moves like a pawn, once square up, Re7. And black is dead. Because if black takes this rook with the bishop, then queen no longer protects f7-square. That's a classic case of interference. And if black takes with the queen, then it's another classic case of deflection, because now our queen can appear on d5, and its mate, Qf7, we simply take on f7, because knight is also under attack. So that example shows the power of interference when it is being used to attack opponent's king. And now we're back in Linares, 1993, the last round. I already secured my first place in the tournament. But played Gata Kamsky, wanted to win the game. And it was a good game. Build up my attack. And as you can see now white is winning, it's still the same number of pawns. But black pawns are very weak. But most importantly black king is in desperate position. While white king is well-protected, black king is in danger. But to deliver the final blow, Qe7, we just have to close this d...

This class was well organized and full of material that I'll be spending years learning to master. Garry's generosity, spirit and passion for chess are truly inspiring. Thank you for making this Master Class. I enjoyed it immensely.

he taught me to look closely at my pieces throughout anything. He also taught me forks, skews, and pins and I can't wait to use all this knowledge on the chess board

What a wonderful experience! I learnt so much, thank you Garry K!

I am not a chess player (not yet). I watched every session carefully and enjoyed it a lot. Indeed I found myself thinking of a chess board while decision making. It came naturally. The inspiration I take with me: Discovering the power of small moves. So thank you for helping building up my software. It's been a pleasure.

Main exercise of interference is after promoting the queen. Since queen vs rook can be tricky if you do not use interference.

I finally could solve my first challenge !! I'm learning a lot from this masterclass

Kasparov is amazing as always, but why is every puzzle shown from black's perspective? Even when playing the white pieces, the board is shows from black's perspective. What's going on? It seems like quite the blunder on the part of the video editor.

On my computer each lesson has a pdf with exercises. Is this not available on iPhone?


what is most fascinating about human mind is that it tends to limit its posibilities by having the predisposition to resign to the impossible. It is why children look at the world with such wide opened eyes: in their imaginative games they tackle the impossible every minute. This lesson reminds exactly of that - a child's approach to things, overflowing with creativity and bringing the most simple solutions to surface. For us adults this looks like scratching your left ear with your right hand. Well apparently there is a reason why one should do that. :) Was it Einstein that said we should always remember to think like a child?

Problem 9.3 solution (in my opinion): 1. ... Re3; 2. fxe Qxf3; 3. Qc2 fxe3; 4 Re1 Bxg3; 5 hxg3 (there in no option) Qxg3+; 6 Kh1 Qxe1+; 7 Kh2 Qf2+

Tyler B.

9.3 has an interesting side line... 1. ... Re3 2. fxe3 Qxf3 3. Qc2 fxe3 where fxe3 doesn't hit the queen as in the line given in the workbook solution. 4. Re1 now if e2 trying to interfere, we can recapture with the queen. I had assumed 3 ... fxg3 4 hxg3 Bxg3... or 3 ... Qxe3+ Qf2 4. fxg3 might be the way forward, but its not clear to me.

Wow this is a powerfull lesson. I can rewatch and watch again. Thank you very much for the eye opening lesson

Seriously who in in the post production of this video series thought it made sense to display the chess board in reverse? When I play chess I move pieces upward away from myself. If you were fortune enough to sit in a room with Gary Kasparov and he put a small study on the board for you to ponder do you think he would orient the board so you moved pieces downward toward yourself? When every single game of chess ever played has people moving pieces upward away from themselves???

Great lesson. Once again you must be aware of your position. Be observant of the sacrifice.
