Very good example!
Also 1... Rd5 does NOT lead to back rank problems after 2. Rc8 Rd8 3. Rxg7 Qb1+ 4. Kg2 Qf5 attacking rook and defending h7. Other lines like 3. Re8 also fails because of the queen check with tempo.
The ...Rd5 line fails for black. After ...Rd5 Rxg7 Qb1+ Kg2 Qe4+ Kg1 and black's rook is pinned with no good continuation.
Thanks GM Melkset verry good .
i would have never seen the 4th and winning idea if not for this video, incredibly instructive video
After going thru this series a few times, MSK chess: Has this great video 20/20 Calculation on Youtube that has helped me tremendously. Good for beginers and intermediate chess players understanding of the series of Calculation. Hope it helps, Here is the link- https://youtu.be/5ybeT02z39E?t=1m12s
Thanks again Grandmaster Melik.
Brilliant, thank you!
Instructive :) Thank you, GM Khachiyan! :)
Youre the best Melik
Maybe it was worth showing one more tactical issue of how to react after 3... d2 4. Rd7
Although Melik might thought this is too obvious that white can't take the rook by 4... Rxd7 because of 5. Qc8+ 5... Kg7 (5... Rd8 6. Qxd8+ Kg7 Qd7+ picking up the pawn) 6. Qxd7+ following by Qxd2. And that white doesn't have any tricks after 4... d1Q because of Queen-Queen-Rook connections.
In my opinion, it is no more and no less obvious than the majority of other tactical peculiarities of decision making in this video. But maybe I'm wrong, and it doesn't even worth mentioning. Or maybe I'm just missing something simple in my own calculations.
11:30 yeah even if I don't see the entire continuation, only the first 3-5 moves and it seems to be good, I'll make that move and figure out the rest afterwards. figured that must be what people do, nothing else seems practical or reasonable. problem I am having sometimes is finding the lines that actually give advantage rather than the lines that merely keep everything equal (with best play from both sides).
Great video Melik :)
@fanofcarlsen GM Khachiyan introduced the principles of critical squares and indirect response. These seem to be central notions to this video, notions that I would assume are largely foreign to (y)our decision making process over the board. Although I've appreciated nearly every video on this site, his structured approach to decision making and plan formulating has won my loyalty as a student.
I like it, Thanks GM.
I really enjoyed this video, but I do not understand how your way of calculating is at all "different". You looked at 4 candidate moves, and analyzed them and picked the best one. What is different about this approach from the usual way?
by GM Melikset Khachiyan
Today Grandmaster Khachiyan begins a new series on the subject of concrete, accurate calculation and how important it is to have this approach when trying to convert and advantage. Often when your opponent has pressure (as white does on the seventh rank in this game), only precise, deep calculation can save your won game. Learn from World Champ Euwe and enjoy the show!
