The position after <12.Ne5> was reached 28 times (some by transposition) with a score of <+8 -4 =16>. The position after <12.b3> led to a score of +5 -1 =3> (again, some transpositions). <12.Rac1> led to +0 -1 =2> and <12.e4> led to <+0 -0 =1>.

There is much to like about reaching this position if we can.

cool stuff

He centralizes his pieces and keeps them centralized throughout while probing for weaknesses.

Once he hits on the right idea, he quickly pounces for the kill and wins:

<<8.Qc2 b6 9.Bf4>

[+0.06] d=26 9...dxc4 11.Bxb8 Rxb8 12.Nxc4 c5 13.dxc5 Bxc5 14.Rac1 Bb7 15.Rfd1 Qe7 16.Nfe5 Rbc8 17.Qb3 Rfe8 18.e3 h6 19.Nd3 Red8 20.a4 Ba6 >

Interesting that OE doesn't show any games where black plays <9...dxc4>. Anyone know why?

BTW, I have a hard time getting excited about playing Bf4 just so we can exchange it for the Nb8 (as shown in <RV>'s line), which arguably helps black by putting his rook on a better square.

So, I'm currently looking at the variant where it continues:

<10.Nbd2 Nd5 11.<Nxc4> Nxf4 12.gxf4>

<<<Rinus Award>>>

<<<Please nominate a <non-premium> member who is making a significant contribution to the World Team. There are many who are, so we hope that you will take a moment to nominate as many of them as you wish. You may post nominations at my forum User: hms123 between now and October 1. We will announce the winner of a one-year premium membership some time during the first week of October. Thank you.>>>

After Peter started this effort, User: zanshin headed it up for a while with help from User: kutztown46, me (User: hms123, and others. User: zanshin asked me to take on the leadership of this effort. I, in turn, asked User: WinKing to join us.

This is the original announcement from <chessgames.com>:

(Chessgames Challenge: M Umansky vs The World, 2009 ) chessgames.com: <The Rinus Scholarship>

For several years, User: chesstoplay (Peter) devised and managed "The Rinus Scholarship", an effort designed to give premium memberships to people who contribute to the World Team's success. The Rinus Scholarship is named in memory of the Chessgames member User: rinus who passed away in August of 2008. Rinus was the first recipient of this award, and remains a shining inspiration to the World Team.

Sadly, due to health problems Peter can no longer continue this effort. Fortunately, some members stepped forward to take over the job. To help ensure its success, we have now incorporated the Rinus Scholarship directly into our website, allowing anybody to donate a premium account directly to the fund. This fund will then release premium accounts to members of the World Team, at the judgement of the new managers.

From time to time you'll be seeing a small banner ad to the left of the board soliciting donations. The proceeds from donations made to this fund will not only purchase a premium membership for a deserving user who may not otherwise be able to afford one, but also will go into a special account used to finance future Chessgames Challenges. In this way, we hope to hire the very finest grandmasters in the world to step forward and take the challenge. So each dollar donated serves two purposes: you put a smile on somebody's face today, and in the future you put a smile on thousands of people's faces when a new Chessgames Challenge begins.

<By the way, keep up the good work - I am impressed with your input to this game.>

in the event of the desired 8. ... b6 and your recommendation of 9.Ne5 what do your engines give as best play, just out of interest? Anything along the lines of:

BTW, I'm also very impressed by your analysis of the position. You know your Catalan.>

Thanks - again.

I have been curious about "water-cooled" systems. But to convert mine to that would take a ton of cash, I'm afraid.

Thanks for those directions - I now have Stockfish operational!>

<Sep-15-10 chancho: I like the approach Razuvaev uses in this Catalan game.

He centralizes his pieces and keeps them centralized throughout while probing for weaknesses.

Once he hits on the right idea, he quickly pounces for the kill and wins:

Another good game, thanks <chancho> for pointing this out.

Check the engine room, I have posted a ton of stuff there. (And I am still working on it.) Believe it or not, as soon as we entered the Catalan, I identified this as one of the possible lines of play. We call it the "Bogo-Cat," some early opening books don't even look at it!!!

I was actually doing only my second or third "deep position analysis" (on possible ninth move alternatives - see a few of my earlier posts) when my box had a hiccup. (Had to re-boot. I actually shut down for half an hour ... following RV's <indirect> recommendation to let my tower cool off.)>

Aha! Nice one - I checked it out, our engines disagree but you searched much deeper than I, so it's no surprise. I posted my analysis in the analysis tree anyway at the node 9.Ne5 - you may want to update it with your better analysis or it might mislead people.

On that note I'd like to remind everyone of the importance of please posting your analysis in the analysis tree! One of the biggest advantages we have over GMP is our greater computing power - so it's imperative that we use this advantage effectively. Posting in forums is grand but it becomes very difficult to navigate when there are 220+ pages of commentary.

So, if you do some deep analysis - please update the analysis tree; there's a text box where you can cut and paste the line at each node (some may find entering every move to be a little tedious). Just a reminder, thanks!
