Fritz 13 Let’s Check Feature

Fritz 13 is adding a new feature that is called “Let’s check”. The feature allows to share engine analysis with other users and upload it to the “cloud”. Such analysis would be easy to look at in one of the Fritz panels:

The benefits of this kind of feature seem very exciting:

  • it will allow fast access to all previously made engine analysis
  • reduce the need to redundantly run engine on positions that someone else has analysed
  • encourage sharing between chess players on an unprecedented scale
  • it actually has a UI that is easy to understand. Convekta’s IDea still seems very complicated to me when I read explanations of how it works

The Video tutorials are brief and to the point:

But the scary aspects of the feature seem a lot more obvious:

  • spying on each other – sounds like the option is on by default!
  • in perspective, this takes us much closer to chess being completely solved
  • ChessBase may control data contributed by many chess players, many engines and so on. While games are now being shared in databases produced by more than one vendor, ChessBase having billions of extra positions stored in their private databases will give them a monopoly over most of chess data, data contributed by their own users, who would now have to pay yearly membership fees to access that data.
  • focus is on engine analysis, although I think this kind of system should have put emphasis on people’s verbal commentaries (Comments Network feature does seem to go in that direction though, although why not instead use existing GM comments that are spread out through their MegaBase already?)

Yes, this is just a tool to help players with what they do – use best engines to solve mysteries of various chess positions. Some would argue that this is inevitable anyway, but I find this tool more disturbing than anything else.

The biggest question I have though – for how long are they going to have enough storage space to maintain trillions of possible chess positions??

Online tactics: a typical sacrifice I missed

DDT3000-Chanchar, 2009, White to move

White won the exchange in a typical IQP/hanging pawns structure, but Black has broken through on the queenside by just capturing on c3.

I played 21. Nxf7 and later failed to win the game. But another typical sacrifice (which I did not have time to calculate) was much stronger.

21. Bxe6!! was winning. If black takes on e6, he loses the f6 knight and is under attack. If Black takes on h3, White takes on f7 with check, and then recaptures the queen, remaining up an exchange and a pawn. There was not all that much to calculate, but I missed this chance in my 3 0 ICC game.

blitz game - rook endgame

Do you analyze your blitz games? I do sometimes, especially when I can't tell what's going on. I played a game on ICC today, where I was Black and in a sharp endgame my opponent ran out of time - my last move was 52. ... g3.
the position is unclear, computer keeps changing it evaluation as well. I can't prove that either side is drawing or losing, but here is how it could have continued if White is not careful: 53. Rf8 h4 54. a8=Q Rxa8 55. Rxa8 Kf7 !! Despite being a rook for a pawn down, Black is just on time to win this game!
56. b5 g2 57. Ra7+ Kf6 58. Ra1h3 59. Kc7 h2 60. b6 h1=Q 61. Rxh1 gxh1=Q 62. b7 Qc1+ -+ Queen wins against knight pawn on the 7th rank.

Chess metrics - monitoring personal progress - Part 2

Here is another graph I generated based on my personal collection of games - this time it's my rating fluctuation on chessplanet server in the year 2007. And that's something that Chessbase or similar products I am aware of don't even support. It's interesting to see that the peak comes in May - the time when I was preparing for the Keres Memorial in Vancouver, so I put a bit extra time into studying chess - and I suppose that extra effort caused my blitz rating to go a bit up as well.
