  Stonehenge: During the game I was looking at 16.Rac1 (or maybe the other rook) instead of Nxd4. Would that have been any good?
Jan-17-11  TheRavenPK: <Stonehenge> After a 5 second analysis I think Black can after 16.Rac1 play for example 16..Qxc4 17.Rxc4 Ne2+ 18.Khi Nxg3+ 19 hxg3
or 16..Nxf3 17.gxf3 (17.Qxf3 Qxe5 18.Rfe1, but black stays pawn up)..

anyway, I think White can achieve nothing more on 16th move than stay pawn down..

  Stonehenge: Thanks, I had a feeling something was wrong with Rc1 but I just didn't see it.
Jan-17-11  TheRavenPK: Btw, nice example of a won opposite bishop endgame.. Black a2-pawn cannot be taken and Black has all the time in the world to come here with his king, win the White bishop and the game..

  Stonehenge: I didn't understand 22.a4, why make that pawn more vulnerable? But I'm no GM ofcourse :)

  Stonehenge: <Smeets>: "I played 14. c4 with the idea to follow up with 16. Rc1 after 14. dxc4 15. Bxc4 Nxd4. Then I noticed, however, that 16. Qxc4! 17. Rxc4 Ne2+ would be winning, not for me, alas, but for black. So I had to settle for 16. Nxd4, just losing the pawn".

So if White insists on playing 16 ♖a1-c1??, he loses an *additional* exchange to the <REMOVAL OF THE GUARD> tactic 16 ... ♕c7x♗c4!.

<Jan Smeets spoiled a fine performance in the tournament so far when he made a serious mistake early in his French game against Ruslan Ponomariov of the Ukraine. Playing white, Smeets sacrificed a pawn in the hope of obtaining good chances only to discover too late- that he had just squandered a fine position. <<<I played (see diagram)

. c4 with the idea to follow up with 16. Tc1 after 14. dxc4 15. Lxc4 Pxd4. Then I noticed, however, that 16. Qxd4! 17. Rxc4 Ne2+ would be winning, not for me, alas, but for black. So I had to settle for 16. Nxd4, just losing the pawn.>>> Ponomariov eagerly rose to the opportunity, exchanging queens and easily winning the end game at his 40th.>

So the 16 ♖a1-c1?? line involves the tactics 15 ... ♘c6xd4! <DISCOVERED ATTACK>, 16 ... ♕c7x♗c4! <REMOVE THE GUARD>, and 17 ... ♘d4-e2+ <ROYAL FORK>.

A lovely tactical sequence, showcasing the power of a <CENTRALIZED KNIGHT>.

Jan-18-11  TheRavenPK: <notyetagm> Nice, I admit I didn't see it.. thank you, but still my line is winning :D yes, I did NOT see it further, but still I think I deserve at least... let's say 70% :P
Jan-19-11  Chesschatology: <The RavenPK> Credit deserved, you <ANALYSED> a <VARIATION> with a correct <ASSESSMENT> which <NotyetaGM> supplemented with a <TACTICAL FINESSE> using his system of <CAPITALISED CATEGORIES> to systematically label every <TACTICAL MOTIF>. What a splendid example of <GROUP ANALYSIS>.

  Stonehenge: Well, after 16.RFc1 Qxc4 17.Rxc4 Ne2+ 18.Kh1 Nxg3+ 19.hxg3 white doesn't lose the exchange. But his position is still nothing to Twitter home about.
Feb-04-11  ReikiMaster: 14.c4 looks like an unforced error.
