  technical draw: <russep> The queen is not trapped..The queen can take at d7.
May-19-07  notyetagm: Here Black makes an -incredibly- instructive blunder with 9 ... ♘f6xd5?.

Position after 9 ... ♘f6xd5?:

Let's see what Martin Weteschnik says in the chapter on <PINS> in his great book "Understanding Chess Tactics", page 48.

<
*) Every undefended piece is a potential candidate for a pin

*) Every attacked piece of yours standing in front of another of your pieces should be considered as pinned

*) Two pieces of the same colour on a diagonal or file should already be regarded as a precondition for a pin

>

Now we see why 9 ... ♘f6xd5? is such a blunder: it creates all the preconditions that Weteschnik indicates lead to a <PIN>! The Black b7-bishop is <UNDEFENDED>, the Black d5-knight is attacked and positioned in front of the <UNDEFENDED> Black b7-bishop, and the Black d5-knight and <UNDEFENDED> Black b7-bishop are <LINED UP> along the a8-h1 diagonal.

So naturally the tactical genius Karjakin (White) sees all of these tactical points and plays 10 ♕c2-e4!, <PINNING> the already attacked Black d5-knight to the <UNDEFENDED> Black b7-bishop.

Position after 10 ♕c2-e4!:

Now the Black d5-knight is <EN PRISE>, it cannot be defended again, and if it moves then the <UNDEFENDED> Black b7-bishop hangs. A very powerful <PIN> indeed.

This may all seem rather obvious but remember that Black here was Germany's youngest GM who totally overlooked the combined effect of all of these tacitcal nuances which the tactical genius Karjakin did not miss.

  whiteshark: I think only <10... Nb4> is the real mistake. Black should have tried <10... f5!?> instead, e.g. 11. Qc4! b5! 12. Qb3 c4 13. Qxb5 Nb6 14. Be3

Good idea. I like 10 ... f5!? 11 ♕c4!: instead of <PINNING> the Black d5-knight to the <UNDEFENDED> Black b7-bishop from d5, the White queen moves to c4 and instead <PINS> the same Black d5-knight to the Black g8-king along the newly-opened a2-g8 diagonal.

Yes, the problem with 10 ... ♘d5-b4? is that the b4-square is -not- an <OUTPOST>. After 14 a2-a3, the offside Black b4-knight is left with <NO RETREAT>.

This is yet another example of a tactical theme which I call: <YOU SHOULD NOT GO FORWARD IF YOU CANNOT GO BACK>. You just end up getting trapped, probably on the enemy's side of the board where you do not belong unless you are in an outpost.

Jul-11-07  jon01: Why didn't Bindrich play 12... Nc2+
Jun-14-10  SpiritedReposte: I agree <jon01>. Two pieces for a rook is better than nothing!
Feb-10-17  Wulebgr: With a different move order through the first five, I and my opponent played this game moves 6-11 tonight. I played Karjakin's move 12, but my opponent went for 12...Nc2+. My game lasted seventeen moves and was a victory for White.
