  patzer2: <MissScarlett> Best play after 33...Rxc4 seems to go 34. Qxc4 Bxd4 35. Rxd4 Qc7 36. Qd5 e3 37. Qa8+ Ke7 38. Rd3 Qb6 39. Qf3 Kd7 40. Rxe3 Qc6 41. Qe2 (+0.83 @ 30 depth, Deep Fritz 14).

P.S.: Even though White appears to gain an advantage after 33...Rxc4, I still think it's preferable to 33...Bxc4?! as it gives Black a better practical chance of holding the draw.

Aug-29-15  epistle: <tpstar: Good Luck Wesley! Keep fighting. =) >

and losing! Yeah!

But did it find this from the original position, i.e., without you walking it through?

It will never happen, Carlsen personifies Hector and Wesley is Achilles.>

Now we know that Carlsen is Paris.

The problem with engines in positions like this is you have to be a pretty strong player to even benefit from their lines. Did Black really have nothing better than 38....Kg8, stepping into a pin? Did he have to play ...Bxf4 (making Re6-b6 possible)?

  patzer2: <MissScarlett> It took until 21 depth for Deep Fritz 14 to pick 33. Rxd6 as its best move with a slight advantage calculated.

After the program reached 25 depth it calculated 33. Rxd6 as a clear best move with a near winning advantage for White.

I did have to "walk it (the Deep Fritz 14 program) through" the line 33. Rxd6 Rxd6 34. Rxd6 Bc7 35. Re6! . Otherwise, Fritz kept wanting to pick the weaker 35. Rd5 to .

For difficult and unclear positions, I normally employ the "walk it through" process of checking the analysis to over 20 depth move-by-move.

P.S.: I'm running Deep Fritz 14 on an i7-4790 3.6 GHZ quad-core processor with 16 GB of RAM. So the program gets to 20 depth pretty quick. Yet after 20 minutes of calculation and reaching 27 depth, Fritz still hadn't found 35. Re6! from the original position (i.e. 33. ?).

Aug-30-15  ozu: <patzer2> Hey, thanks for looking into that!

  patzer2: <Did Black really have nothing better than 38....Kg8, stepping into a pin?> I think so, as the threats of 39. Rc6 or 39. Qb5 with the threat of a royal Rook fork are otherwise too powerful.

If 38...Bxh6 here (diagram below),

39. Nc7! Qa7 40. Qc5+! Kg8 41. Rxg6+ hxg6 42. Qxa7 wins the Black Queen with a clever discovered attack with check.

<Did he have to play ...Bxf4 (making Re6-b6 possible)?> According to Fritz, Black's next best alternative is 35...Bd8, but after 36. Qc4! (a move I had to "walk through") Black is busted.

Also futile is 35...Qc8 36. Qc4! (+3.12 @ 22 depth).

So it rated 35.Rd5 as 'near winning advantage'? 25 ply is impressive; what hardware do you have?

  patzer2: <MissScarlett> My hardware is an i7-4790 3.6 GHZ quad core processor with 16 Gb of 1600 MHZ RAM and a 1 GB 7200 RPM hard drive.

The software is Deep Fritz 14x64.

Sep-02-15  mrandersson: patzer2 1tb you mean? Out of all the engines to use and pick from ie houdini stockfish komodo do you find deep fritz 14 better to use or is it a case of use what comes with the software type thing?

With your cpu my old personal fav Zappa mexico 2 would run like a dream.

Feb-08-16  The Kings Domain: First got to know this game in a YouTube video, I wanted to know the source of So's dissapointment :-). Another fine classical victory by Carlsen.
