Here are some games from round 3. I used Fritz 13 to help me evaluate thepositions and also comments I heard from the players after the games. Thegame Suhas Kodali vs. David Herscovici includes comments provided byDavid.

� Colwell, Andrew (1995) July Knockout Swiss 2018� Castaneda, Nelson (2356) Nimzo – Indian – E44

In the variation of the Nimzo - In-dian played here white has devel-oped the king-side knight to e2 tobe able to recapture with this knighton c3 in case black responds 6. ...Bxc3. So white would like to havethe pair of bishops without damag-ing the pawn structure. However, itis not clear that the pair of bishopsis an advantage because the struc-ture of pawns in the center is yet tobe determined. The move I played6.... Be7 is a common alternativeto the exchange in c3. The fight inthe middle game is about the center.With his next move Andrew aimsfor some space advantage with d5.Black first plan is to undermine the

center of white attacking it with e6and c6.

7. d5 d6 8. Ng3 c6 9. e4 Re810. Be2 a6 11. 0–0 Qc7 12. Be3

My move 10... a6 does not seem tobe that good according to Fritz 13.I was aiming to get a pawn struc-ture alike the one from the Benonidefence capturing e x d5 at somepoint and playing g6. I wanted tohave the queen on c7 and a6 was toavoid jumps of the knight to b5.

Instead of 13. Rc1 it was better toplay 13. dxe6. Then white couldhave played with the advantage ofspace incorporating moves such asf4, and b4. It would be difficult forblack to advance any of the pawnsranging from the a to the e file with-out creating weaknesses.

After the move 14. f3 white hasto be alert to tactics involving thepotential capture of Rxe3. This isnot obvious now but it could havebeen a decisive factor later on in thisgame.

18. Qa4 Nb6 19. Qd1 Bg720. Qd2 Nbd7 21. Na4 h522. Nb2

rZbZrZkZZ0lnZpa0pZ0o0mpZZ0oPZ0Zp0Z0ZPZ0ZO0Z0APM00M0LBZPOZ0S0ZRJ0

White pursued an interesting planof improving the knight from c3 toc4. But there is a problem with

the execution. After the game An-drew told me that he was worriedabout the knight on b2 being indanger. It turns out that he wasright but we both missed the tac-tics that the computer immediatelyshows 22....Nxd5 The point is thatafter 23. exd5 then black can takeon e3 23....Rxe3. I dismissed 22....Nxd5 on the grounds that the queencaptures on d5 attacking the rook ofa8. What I didn’t realize is that af-ter 23. Qxd5 Bxb2 24. Qxa8 thequeen is trapped after 24....Nb6.

So 22. Nb2 is a mistake that loosesa pawn and black’s next move is amistake that misses the opportunityof winning a pawn.

The last move is a standardmanuever that occurs often in theBenoni. When (or if) white cap-tures on b5 then the rook from a8attacks the pawn of a3.

White’s knight on g3 was not doingmuch so Andrew tries to bring it tothe queen side. Unfortunately forhim the knight on e2 is on the wayof the queen which is made clear bythe move 32. ... Rb8.

David Herscovici has provided some comments to his game with Suhas. Ihave inserted some of his comments in blue.

� Kodali, Suhas (2100) July Knockout Swiss 2018� Herscovici, David (2117) Sicilian - Dragon – B70

rZbl0skZopZ0opap0Zno0mpZZ0Z0Z0Z00Z0ZPZ0ZZNM0Z0Z0POPZBOPOS0AQZRJ0

This position is very similar to theposition in Mario Guevara – SuhasKodali from the previous round.There the game started as an En-glish opening but the treatment theplayers gave was the one of a Sicil-ian dragon with the colors reversed.Now that David is playing the Si-cilian Dragon we could say that theposition is one of the English open-ing with the colors reversed.

After the game Suhas, David, Rick,and other players analyzed the gamethoroughly. Unfortunately I missedtheir comments regarding this po-sition. This position is studied inthe book of Gufeld and Stetsko onthe Sicilian Dragon. In my opin-ion black has equalized. The crit-ical moves 11. e5 and 11. f5 havebeen thoroughly analyzed. Gufeldand Stetsko point out that at thispoint black is threatening not onlyto jump to c4 with the knight butalso the exchange sacrifice Rxc3that would be good is black canget the e pawn for it and damagethe structure of white pawns in thequeen side.

The book I have of Gufeld and Stet-sko is quite old. I am aware thatthere are newer probably deeperbook on the dragon but I am notfamiliar with them.

13. Bd3 is a standard manuever inthe Sicilian. It is not convenient forblack to take on d3 because after c2x d3 the pawn of e4 gets a good de-fender and the Knight from a5 can-not jump to c4. Now white queencan be brought to the king side viaf3.

I don’t understand the point of themove Re8. Perhaps it is to defendthe pawn of e7. Gufeld and Stet-sko recommend 13.... b5. It makessense for black to try to get space inthe queen side.

White has won a pawn and isthreatening to exchange queens. Toavoid this simplification David putsthe queen in a bad square. Itwas better to play 21....Qb6 withsome counterplay. White couldhave gained a decisive advantagewith 22.Bb5 Nc6 23.Rf4!h intend-ing Rf4-h4-h8m

Black has two pawns for a piece.Now Suhas forces the exchange ofone rook and with good techniquewins the game. Observe how heimproves the postition of the rook,knight and king. He blocks thepawns of the king side with theknight, brings the king as far as itis safe and penetrates with the rookthrough the only accessible openfile.

It seems that black wishes to clearthe h1 - a8 diagonal of pawns to takeadvantage of the fact that white hasno light square bishop. It would be

good for black if he could play c xd4 and advance the pawn from c6to c5. However, this is not so easyto accomplish as the game shows.White on the other hand wishes toblock the pawn of c6.

This endgame is difficult to play forblack. 46. ... d3 is a concession. In-stead black should have traded thed pawn for the h pawn with 46....Kg5. Then the game could haveended in a draw.

Now Joe gets another object of at-tack that is the penetration with hisking to the queen side via b4. Ricktried to oppose white’s king with hisking but that was a lost battle.

White will win another pawn andget passed pawns on both sides.Very well played endgame by Joe.It was very difficult to find the rightmoves for black with limited think-ing time.
