NK jeugd met Tobias

Tobias deed vorige week mee aan het Nederlands kampioenschap voor A-jeugd (tot en met 18 jaar) in Almelo. Hij had zich een paar maanden geleden geplaatst voor de finale via de online voorrondes. Het was van te voren al duidelijk dat het voor Tobias een zwaar toernooi zou worden. Tobias heeft een rating van 1443.  Dat is wel een beetje laag ingeschat, maar toch: aan het toernooi deden negen schakers mee met een rating boven de 2000, met een uitschieter van 2292.
En het werd ook geen gemakkelijk toernooi. Uiteindelijk moest Tobias met een score van 1,5 uit 7 genoegen nemen met een plaats in de achterhoede. Toch: alleen al het feit dat je je plaatst voor het Nederlands kampioenschap na zware selectietoernooien is al een prestatie om trots op te zijn. En volgend jaar nieuwe ronde nieuwe kansen: met de opgedane ervaring kan het alleen maar beter worden.

Tobias was zo vriendelijk om drie van zijn partijen van commentaar te voorzien voor de website. In de eerste partij laat Tobias met zwart zien hoe je gebruikmaakt van het loperpaar in een open stelling. De tweede partij is een moeilijke positionele strijd, waarin Tobias lange tijd goed meekomt. Uiteindelijk laat zijn tegenstander zien waarom hij een veel hogere rating heeft. En de derde partij is vooral grappig omdat er vanuit een verloren stelling toch remisekansen ontstaan. In een eindspel met toren tegen twee paarden en een pion is het enige wat je hoeft te doen de pion slaan: met twee paarden is mat zetten niet meer mogelijk. Helaas kon Tobias de juiste weg naar remise in tijdnood niet vinden.

1. d4 f5 2. Nc3 Nf6 3. Bg5 {I find this move order of the Dutch very annoying}
3... d5 4. Bxf6 exf6 5. e3 Be6 6. Bd3 Nc6 7. Nge2 Qd7 8. a3 {This is the last
theoretical move, white's plan is b4, black can respond with Bd6, Ne7 and 0-0
with preparation of kingside pawn push} 8... a6 9. O-O Bd6 10. b4 O-O {There was
another game in the NK A two rounds earlier with 0-0-0 which ended badly for
black} 11. Qd2 Ne7 12. f3 {12 Pxd5 Pxd5 13 c4 Pxe3 14 Dxe3 c6 and I am happy
here with the bishop pair and plenty of resources ro defend any further pawn
breaks such as d5 or b5.} 12... b6 13. e4 {Whites whole idea of f3 and e4 will
backfire as het opens up the position for my bishops and I anticipated that so I
prepare a b6-c5 break for further opening of the position} 13... fxe4 14. fxe4

the king not ending up in check after Qxd5}) 18... Rfd8 19. Nf4 Bf7 20. Rf3 Qc7
{My position is open and I am really happy about the bishop pair, now I just
need to focus on the queenside pawns and push my soon a-pass pawn} 21. Qc1 cxb4

1. c4 e6 2. Nf3 d5 {[%xcpdao l,t]} 3. e3 {I wanted to avoid the deep theoretical
territories in the Queens Gambit} (3. g3 Nf6 4. Bg2 Be7 5. O-O O-O {This would
transpose into a Catalan}) 3... Nf6 4. b3 Nbd7 5. d4 c6 6. Bd3 Bd6 7. Bb2 b6 8.
Nbd2 Bb7 9. O-O O-O {Here I finished the principles of development and started
thinking for a middle game plan. I opted for a e4-break followed by d5 to open
up the diagonals for my bishop. The computers plan is to play Ne5 with f4 and
eventually do a Rf3 rook lift and move to h3.} 10. Rc1 c5 11. Qc2 Rc8 12. Qb1 {I
was anticipating any future dxc4 and cxd4 business that could lead to tactics
with the rook pointing at my queen.} 12... Qe7 13. Rfe1 {Now I am ready for e4
break but my opponent anticipated that.} 13... dxc4 14. bxc4 e5 {I can close the
position with d5 and e4 which gives me a comfortable positional edge with the
space advantage and the protected passed d-pawn.} 15. d5 Rce8 16. e4 Nh5 17. g3
g6 18. Nh4 Qd8 19. Re3 Bc8 20. Rf1 Ndf6 21. f3 Nd7 {The last 5-7 moves were all
closing the kingside and stopping any potential counterplay before I move my
pieces to the queenside and attack weaknesses in light squares and  a7, b6} 22.
Qe1 {Looking at a4-a5.} 22... Qc7 23. Nb1 {I really like this move as it allows
my knight to move away from my queens diagonal and maneuver to b5 via a3.} 23...

the king side}) 27. a4 Nb8 28. a5 f5 {My opponent decides for counterplay before
his queen side collapses[%xcpdao l]} (28... bxa5 29. Ra2) 29. Rb2 {I was getting
concerned about my time as I still had to do 10 moves till time control and my
opponent had a 15 minute edge.} (29. axb6 Qxb6 30. exf5 gxf5 {This would have
given me a big positional edge with new e5  weaknesses and c4 safe from any b5
undermining my passed pawns.}) 29... Na6 30. axb6 axb6 31. Bd2 Rf7 32. Bc3 Bf8
{[%xcpdao l]} 33. Qd1 (33. exf5 gxf5 34. Na3 Nb4 35. Bb1 Bd7 36. Re2 {This would
have given me big advantage with rook swinging back to target e5}) 33... Nb4 34.
Na3 Bd7 35. Qd2 Ba4 36. Nc2 b5 {My opponent playing too strong for me, fixing
his weaknesses with b5 and creating new counterplay against my king over g1-a7
diagonal} 37. Nxb4 cxb4 38. Bxb4 bxc4 39. Be2 {I had to use all my time to
calculate the last combination and making sure that I am not completely lost
afterwards. At this point tables turned and I was defending.} 39... fxe4 40.

continued a bit but at this point my position collapsed and black has a very
strong passed c3 pawn. I think this game was probably one of the better
positional games I played until the b5 break.} 48... Nxe4 49. Bd3 Nxg3 50. Rc1

from someone who plays 1. b4 in an agressive way} 9. Be3 h4 10. Qd2 (10. exf5

king.}) 10... hxg3 11. fxg3 fxe4 12. Bxe4 Bf5 {I could have kept the game calm
with g4 but after some time I decided on sacrificing the h3 pawn for some
counterplay on the uncastled black king} 13. O-O-O Bxe4 14. Nxe4 Rxh3 15. Nf4

sacrifice which would have given me an almost winning position} 17. g4 Qd7

my active pieces, g5 was also a good attempt the would restrict his pieces.}
