Today I have some important topic to discuss with you. Its about ‘chess calculation’

So, without further ado, let’s get started!

Example

Avetisyan – Anton Guijarro

Black to move

It’s Black’s turn now in the above position. Please spend some time thinking about the game situation and come up with how the Black player should have continued.

Yes, Black has got an amazing move – 28…Bxh3! Of course, this is a very obvious move.

But were you careful to look at White’s counterattacking move? Speaking about calculations, you MUST think of the consequences of your moves – you need to calculate the most important variations.

Yes, White has a counter-blow 29.f4!? Did you calculate this move, honestly? If yes, then accept my congratulations!  Now moving the knight is bad, as gxh3 will lose a piece.

[29.gxh3?? Nf3+–+ should of course be avoided!; 29.Rdc1 Bd7 Black has simply won a pawn.]

So Black plays 29…Bg4! [29...Ng6 30.gxh3 Nxf4 31.Qe3± gives White a good position.] 30.fxe5 [30.Rdc1 Ng6µ] 30…Bxd1 [30...dxe5 is also a good move.] 31.Qxd1

Black to move

[31.exd6 does not work because of 31…Qc3 32.Qb6 (32.Qxc3 Rxc3–+) 32…Rd7 33.Rxd1 Qxb3–+]

31…dxe5µ Black has two pawns and a rook for two minor pieces, but the most important thing is that the White king is weak and Black has a very active rook on c2. Black has a clear advantage and went on to win.

32.Nd2 f5 33.Bd3 Rc3 34.Nf3 Qc5+ 35.Kh1 Qe3 36.Nxe5 fxe4 37.Bf1

Black to move

37…Qg5 38.Qd4 Rc1 39.Rxc1 Qxc1 40.d6 Qxf1+ 41.Kh2 Qf5 42.Qd5+ Kh7 43.g4

Black to move

Qf4+ 44.Kh3 Qe3+ 45.Kh2 Rf8 46.Ng6 Rf4 0–1

Well, that was lengthy bit of calculation indeed. But remember, there is no limit to YOUR huge mind Now, I’m going to give you some practical exercises which you can try to solve yourself.

Maybe to motivate yourself, you can set a target and calculate. For instance, for a puzzle, you can set a target of 10 moves. So you will calculate 10 moves (this is just an example) from the given position, and finally you may check your results by seeing the whole game.
