Nc3 d6 4. f4 Nf6 ({I still play} 4... a6 {, now and then,  but I was in a solid mood that day.}) 5. Nf3 O-O 6. Bd3 Nc6 7. e5 dxe5 8. fxe5  Nh5 9. Be3 Bg4 10. Be2 f6 11. d5 $5 ({The main line goes} 11. exf6 exf6 12. Qd2  Ne7 {, when White has to decide which way to castle.}) 11... Nxe5 ({This was a  decision driven by the fact that the alternative did not attract me. I felt  that} 11... Bxf3 12. Bxf3 Nxe5 13. Bxh5 gxh5 14. Qxh5 {, followed by 0-0-0,  would just be better for White.}) 12. Nxe5 Bxe2 13. Qxe2 fxe5 14. O-O-O {So  far it is pretty forced.} Qd7 ({In case you evaluate 15.Qb5 in the game as  better for White (as the engine does at first), then} 14... a6 {makes sense.  However, I belive 15.Qb5 is nothing to worry about.}) 15. Qc4 ({On} 15. Qb5 {  I was planning} Qg4 (15... Qxb5 $5 16. Nxb5 Rfc8 17. Nxa7 Rxa7 18. Bxa7 b6 19.  Rd3 Nf4 {is far from clear.}) 16.

I only  considered ideas where White tries to keep the knight away from f4.} ({After}  16. g3 {my plan was to continue like in the game:} Nf6 17. Rhe1 Ne8 18. Qe2 Nd6  19. Kb1 Rae8 {and Black is doing fine.}) 16... Nf6 ({I did not like the fact  that White will be able to install his knight on e4 after} 16... Nf4 17.

Bxh6 Bxh6+ 21. g5 Bg7 22. h5 {I had a feeling that I would survive this,  but it was not clear to me exactly how. Houdini considers} Qf5 23. hxg6+ Kg8  24. Qh5 Qf4+ 25. Kb1 Rf5 $19 {to be completely winning for Black, but this was  far from easy to evaluate during the game.}) ({There is something to be said  for} 20. Kb1 {, renewing the threat of Bxh6 (since the g5-pawn does not fall  with a check). I would probably have played} Kg8 {when} (20... Rad8 {is better  according to H. since} 21. Bxh6 Bxh6 22. g5 Bg7 23. h5 Kg8 24. hxg6 Rf5 {still  defends}) 21. Qg2 Rad8 {leads to an unclear game.}) 20... Rf4 $6 {This move  has the advantage of leading to a position that is easy to understand (and  defend). At this stage I was still quite happy with a draw and tried to steer  the game towards positions where I felt comfortable, rather than trying to  find some kind of advantage.} ({With a more aggressive mindset I might have  gone for} 20... b5 $1 {, forcing Nc3 to explain it self.}) 21. Bg3 Rxg4 22.  Bxe5 Rf8 {So, all my pieces are active and I still have an extra pawn. My  kingside is in fact quite solid, since there is no way to attack the pawns  without trading more pieces.} 23. Rde1 Bxe5 ({The engine prefers} 23... h5 {,  when the h4-pawn will become very weak in the endgame. Also, it is easier for  the rook to defend g6 than it is to defend h6, after the exchange of h4-h5 for  g6-g5.}) 24. Qxe5+ Kg8 25. h5 ({The endgame after} 25. Qxe7 Qxe7 26. Rxe7 Rf7 {  is very unpleasant for White. Partly due to the weak h-pawn, and partly  because Black is much better coordinated.}) 25... g5 26. Rhf1 Rgf4 27. Rg1 ({  It is better to play} 27.

I do not know.} ({The stronger line goes  } 31... Qd7 $1 32. Rh8 Qd6 {when Black is winning.})) 29... Rf2 {Now I thought  I would win easily, but that turns out to be an overstatement.} 30. Nd1 $1 Rc8  31. Qxc8+ Nxc8 32. Nxf2 Qxf2 ({The engine prefers} 32... Qf4+ 33. Kb1 Qxf2 34.  Rgf1 Qg2 {,when the circumstances seem to favour Black.}) 33. Rgf1 Qc5 34. Re6  $2 ({Here} 34.

The point is that I will win the pawn endgames if I get to  exchange my queen for rook and pawn on d3. Without the b3-pawn, this would not  be possible.
