Sally Simpson: Hi Diademas,
As I said he missed the b5-b6 move all together.
Common trait, we have all been there, we get so wrapped in our own schemes and miss completely what the other guy is up to.
it's a nice cunning idea but flawed.
Remember once writing a piece saying one should not seek ideas in chess. Just play reaction chess. Makes moves to cover your opponents threats. Let them have the ideas, all you need do is find the flaw.
It requires a lot of patience, something I do not have, but I often write telling people to do things what I can't, especially when it comes to endings. (those can do...those that can't teach!)
Tarrasch said something similar about plans.
Wait till your opponent has a plan, it will be wrong and you can react against it.
Would like to have seen a vid of Navara's reaction when Giri played b6.
