{I am happy about this game. It was played in the penultimate round of the
Olympiad and before the 10th round the Polish men's team was somewhere around
25th place, which was definitely not the position of our dreams.  Therefore,
in order to finish the tournament well we had to win the last 2 matches. That
day our opponent was the solid team of Iceland. We managed to win this match 2,
5-1,5 with 3 draws and my win. However, the match was very unclear and it was
actually thanks to my win and heroic defence by Kacper Piorun that we made it.
} 1. d4 Nf6 2. c4 b6 {Surprise, I did not expect to see this line on that day
and I was not prepared for it. What is interesting is that the same line
appeared on 3rd board in the game Kjartansson-Piorun.} 3. Nf3 (3. Nc3 Bb7 4. d5
e6 5. a3 {was played in the aforementioned game and (also) in my game against
Jaan Ehlvest from World Rapid Chess Championship 2015. This time I decided to
choose another (less known) line.}) (3. f3 {is most probably critical, but I
think that the line I played with Ehlvest is also promising.}) 3... Bb7 4. Nc3

Defence, but quite an interesting move, aiming to get some kind of quite good
version of the Queen's Gambit Declined. However, it has some drawbacks.} Ne4 {
The correct reaction.} (5... dxc4 6. e3 e6 7. Bxc4 {should be slightly better
for White}) (5... e6 6. cxd5 exd5 7. Qa4+ $1 {looks very unpleasant for Black.}

move is} Nxc3 ({if} 6... Nxg5 7. Nxg5 e6 {Black seems to force White's knight
to retreat and level the material but...} 8. Nxf7 $3 {(great resource)} Kxf7 9.

maintains superb compensation for a piece and a strong attack.} Kxe6 (9... Kg8

Practically Black's position is about to collapse.}) 7. bxc3 Qxd5 {where Black
still is not commited to developing his bishop to g7 and can still play in
Queen's Indian style e6 and develop pieces in this way. White is maybe still
slightly better but the position is full of play.}) 6... Nxc3 {I think that
this move is inaccurate.} ({It was much stronger to play first} 6... dxc4 {
and in the event of} 7. e3 ({It is maybe better from a practical point of view
to take back the pawn immediately} 7. Qa4+ Qd7 8. Qxc4 Nxc3 9. Qxc3 e6 {
but Black should not be that bad there.}) {then} 7... Nxc3 8. bxc3 b5 $1 {
just trying to stay a pawn up! White should have some compensation obviously
but a pawn is a pawn - White still needs to prove compensation. A similar
position appears sometimes in the Grünfeld. For example,} 9. Be2 $5 (9. a4 a6

behind in development but so far he is a pawn up and the position has a closed
rather than open character.}) 7. bxc3 g6 {Transferring to a Grünfeld-like
position, where actually I felt comfortable, as I play this opening also with
Black. But this version seems to be pretty good for White.} ({Now, in the
event of} 7... dxc4 {White would have had additional resource:} 8. e4 $1 {

possibility to play c5. But White still is slightly better.}) 11. O-O O-O 12.

should I continue?} 13. Qe2 $6 {This logical looking and developing move
appears to be inaccurate. It gives Black good chances to equalise!} ({A
stronger move was} 13. Bb5 {with the idea that} a6 {is followed by} 14. Bd3 $1

difficult for Black to play c5 in the future. White maintains a pleasant
advantage:} Na5 15. Qb1 Qd8 16. Rd1 $14) 13... e5 $1 14. d5 Ne7 $6 {Returning
the favour. This backward move is very dubious.} (14... Na5 $1 {was correct

but I don't think that is so bad - after the exchange of those bishops White
continues with play on the light squares and the initiative on the queenside.}

position (or overestimated my position). Now White is just very close to
winning. Instead of this Black had some other options.} (18... Bf6 {was bad:}

already drawn his game with Hannes Stefansson) and there were still 2 games in

positions but they finally managed to save their games and we won the match.}

{This game from the 9th round of the open chess tournament in Bogota (Colombia)
was the most important for me. The win in this game allowed me to win the
tournament on tie-break. My photo report from this tournament was published on
the ChessBase site: German - http://www.chessbase.de/nachrichten.
asp?newsid=11182. Spanish - http://www.chessbase.com/espanola/newsdetail2.
asp?id=9064.  My opponent in this game was the talented young player Anton
Kovalyov. Born in Kharkov (Ukraine), for a long time he lived in Buenos Aires 
(Argentina), where he learned to play chess. Later his family moved to
Montreal (Canada), where they live now.} 1. Nf3 {Usually my opponent doesn't
go for the principled main lines with White, preferring the positional 'no
theory' play. Another of his favourite moves is 1.c4.} Nf6 2. c4 b6 3. g3 Bb7
4. Bg2 {This order of moves has been played against me very frequently - 58
games played since 1986 with this move order so far. Usually I play 4...e6
here, which remains my main answer here. But in this game I decided to choose
a much more complex continuation with less theory. It is more risky, but also
gives more winning chances - an excellent choice for a game which you want to
win!} g6 {I played this move for the 1st time in 1986, winning that game
against V. Zvonitsky. Later I almost stopped playing this move, concentrating
on different plans after 4...e6. The most famous is my setup with Nb8-a6 which
brought me lot of nice victories. Another plan was with c7-c6 and d7-d5
tranposing into the Catalan. But nowadays it seems that both lines are
exhausted with too much theory. So I have returned to the old move 4...g6. The
main advantage of this move is, that the bishop on g7 is better placed than on
e7 after the typical white advance d4-d5. It becomes very, very active. As we
see precisely in the present game, the dark-squared bishop helped me to win
this game. The drawback of this move is, that it takes 1 extra move for Black
to finish the development, because in any case he has to play e7-e6 at some
point. Thus White has 1 extra move to try to seize the control over the centre,
playing d4-d5 and e2-e4. So White's main strategic idea in this position is to
try to seize the centre. If he manages to do so usually he gets the advantage.}

1. c4 Nf6 2. d4 c6 {At least this is a move order I can understand! Far more
curious to my mind are the considerable number of games which reach this
position via 1 d4 Nf6 2 c4 c6. I can see ways in which the early ...Nf6 rather
restricts Black's choices in the Slav, but none in which it harms White's. I
did have one opponent early this year who employed this move order, but I put
this down to a desire to provoke the Trompovsky(!?) something I rather
respected after a string of opponents trying to do the opposite!} 3. Bf4 $5 {
Just about the only attempt to use Black's move order to get 'something
different'. However, this game provides further evidence that the cost may be
a bit high.} Qb6 $5 {This looks likely to cause a healthy degree of
inconvenience. Indeed, after this, the whole game rather smacks of White
responding to her opponent's threats rather than creating any of her own.} ({
White's unusual third move is all about the fact that after} 3... d5 4. e3 {
Black is not guaranteed any familiar Slav patterns. One successful example of
White's idea leading to a pleasant QGD:} e6 ({Others look more combative eg.}

I like this move. It looks much more fun to try and exploit White's dark
squared liberties by playing ...e5 than to settle for a static centre. I must
admit, when I saw this curious, mildly Trompowskiesque position on the
database I assumed it to be quite original. How naive! Its not that easy to
break new ground these days. Of the alternatives:} ({Of course not} 5... Qxd4
