Podgaets Memorial Odessa UKR (10), 29.11.2010

Never say never - but already in 2009 I decided that 2010 will probably be the last year that I'll play in the classical/long tournaments. Additionally since I'm still in the top 1,000 players it is a good time to go. I'm glad then, that there were a couple of well played King's Indians in the November Odessa event.
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.Ne1 Nd7 10.Nd3 f5 11.Bd2 Nf6
Calmer is 11...Kh8 and, especially, 11...fxe4. There is also 11...f4 which is usually considered to be dubious but maybe things are not that clear.
12.f3 f4 13.c5 g5 14.cxd6
Topical here is 14.Rc1 Ng6 and now 15.Nb5!?. The old main line is 15.cxd6 cxd6 16.Nb5 Rf7 17.Qc2 Ne8 18.a4 h5 19.Nf2 where dubious for Black is 19...a6?! 20.Na3! as in Ivanchuk-Golubev, Armiansk ch-Ukr jr 1983, this game, which is not yet in databases, opened my 2006 book on the K.I.D.
14...cxd6 15.Nf2 Ng6
The alternative 15...h5 invites White to insert h3 or to switch to positions with an early Ra1-c1, because 16.Qc2? is answered by 16...g4!. After the text White possibly has a larger choice, which is not necessarily good in a practical game.
After 16...h5 17.Nb5!? (usual is 17.h3) it can be dubious for Black to go for 17...g4 18.Nc7 g3 19.Nxa8 Nh7 though it deserves to be checked.
After 17...Ne8 18.a4 h5 the unusual 19.Ncd1!? led to a long manoeuvring fight in Aronian-Nakamura, Bursa 2010. Eventually, White won that complex game.
18.h3 leads to the main position of the Rfc1 set-up. (It occurred, as I remember, in my 1982 Ukrainian junior championship game against M.Gluzman, now an IM and chess coach in Australia ... During the last few years, I've been collecting all my preserved games at my web page. Alas, the majority of games from the junior tournaments have been lost). After the text, Nc7 must be prevented.
Not 19.Nxa7?! Bd7! (much stronger than 19...Rc7? 20.Ba5) 20.Nb5 g4! with Black attacking (as in B.Maksimovic-J.Todorovic, Yugoslavia 1991).
A move, which can be useful in attack and defence (still, in some lines Black may regret that the bishop interferes in the development of the queen to h4 or g5). Premature is 19...a6?! 20.Na3!; 19...Bf8 is, generally, more typical than the text; 19...Nh4?! is also a typical move, but here it allows 20.Nxa7! Rc7 21.Ba5 Rxc2 22.Bxd8 +/-. After 19...Bd7 there was a recent game, as the database shows: 20.h3 N (I was not sure about 20.Ra3 a6 21.Nc7 but 21...Bxa4 is maybe OK for Black) 20...Bf6 21.Ra3 Qb8 22.a5 Bd8 23.Nc3 Matlakov-Baryshpolets, Chotowa Wjun 2010: it looks playable for Black who could have tried 23...Nf6!?.
A tempting move. White correctly avoided the line 20.Nxa7 Rc7 21.Ba5 (a better chance is 21.Nc6! bxc6 22.dxc6 which is quite unclear at first glance) 21...Rxc2 22.Bxd8 Rxe2 (it is good for Black to have a bishop on f6 here!) 23.Bxf6 Bd7-/+ where Black wins a piece. Other options were 20.a5 and 20.h3 and a shift to a position from Matlakov-Baryshpolets is not improbable.
20...a6 21.Rc3 Bd7
Not 21...axb5? 22.Rxc8 +-.
In the variation 22.Nc7 Nxc7 23.Rxc7 Bxa4! Black should be OK.
The start of the attack which at least gives Black serious practical chances. The line 22...Qb8 23.a5 Qa7 24.Nc4 Bd8 did not attract me (but maybe was playable?). There were 'short' moves like 22...Rb8 where White cannot play 23.Nc4? (23.h3!? is normal) because of 23...b5 -/+.
A curious idea was 23.Rc6 - sometimes White can play like this.
Already here White had a complex choice.
After 24.Nxb5!? g4 25.fxg4 Black can consider 25...Bh4 (after the obvious 25...hxg4 26.Nxg4! Black cannot win a piece without losing an exchange. For example, 26...Bxb5 27.Bxb5 Qb6+ 28.Kh1 Qxb5 29.Nh6+ Kg7 30.Nxf7 Kxf7 and White can be somewhat better here) where 26.g3 can be checked (Avoiding 26.gxh5 Bxf2+ 27.Kxf2 Qb6+ 28.Kf1 f3!). If 24.Bxb5 Black plays 24...Rxa3! and should be OK as I thought. Again possible was 24.Rc6!?.
I also examined 24...b4 25.Rxb4 g4 26.fxg4 Bh4 but was afraid that it can be too much. In particular, I was far from sure whether Black has enough after 27.Be1 Bxf2+ 28.Bxf2 hxg4.
Also a serious move is 25.Bxb5 where I intended to continue 25...Bh4!?.
Critical was 26.g3! where after 26...b4!? (I disliked 26...hxg4 27.Nxg4!?; after 26...fxg3 27.hxg3 which was what I intended to check first, maybe Black can even try something like 27...Nf4) 27.Nc4 (avoiding 27.gxh5 fxg3 28.hxg3 Nf4!) 27...fxg3 28.hxg3 Ba4 29.Qd3! is engine's suggestion for White. All this is very compex.
26...Bxf2+ 27.Kxf2 Nh4
Probably correctly abstaining from 27...Qb6+ 28.Kf1 Nh4.
It is tempting to involve the rook in the defence, but after this move the white pieces lose co-ordination and things are getting even more dangerous for White. 28.Kg1!? could have been preferable, after which Black has a number attractive options.
Again abstaing from the check 28...Qb6+ 29.Kf1 Kh8 (or 29...Ng7).
29...Qb6 ('very strong' - Bogdanovich) was not clear to me, so I activated one more piece. 30.Bd1!? is a suggestion by 'Fritz' then (30.Bf3? Nxf3 31.Rxf3 b4 -/+; 30.Be1 f3 31.Bxf3 Nxf3 32.Rxf3 Rxf3+ 33.gxf3 Bh3+ 34.Rg2 Qe3! =/+) and if 30...f3 31.g4.
It is at least logical to exchange rooks before pushing ...f3.
31.Rc3 Rxc3 32.bxc3 f3!
32...Nxd5? 33.exd5 Nf5 34.Bf2 Ne3+ 35.Bxe3 fxe3+ was considered by me as an alternative, but I could not see the full compensation there. In fact, even 36.Bf3 (36.Ke1! Qh4+ 37.Kd1 +/- was the main reason why I did not go for that line) 36...Qh4 37.Qe2! turns out possible, because 37...e4?! (37...Qa4!?) fails to 38.Qxe3 with the idea of 38...exf3 39.Qh6+ +-.
Not 33.gxf3?? Bh3+. After 33.Bxf3 Nxh5!? Black has a strong attack for not so much sacrificed material.
33...Ng4?? is nice, indeed, but it does not work at all: 34.Bxd8 Nxh2+ 35.Kf2 Ng4+ 36.Kg3 +-
34.Kxe2 b4! -/+
Sacrificing one more pawn (in order to have access to the d4 square) is the key move, otherwise Black might have had problems. For example, 34...Qb6? 35.Rf1 Bg4+ 36.Kd2 Nxd5 37.exd5 Rxf1 38.Qg6 where Black should fight for a draw by 38...Rf2+! 39.Bxf2 Qxf2+ 40.Kc1 b4!. Or 34...Bg4+? 35.Kd3!.
After 35.Qd2 bxa3 36.Qh6+ Kg8 37.Qg6+ Kf8 38.Qh6+ Black, importantly, has 38...Ke8 -/+. My main intention after 35.Nc4 Bb5 36.cxb4 was 36...Qc8 (36...Rc7! -/+ and if 37.Rf1?! Qc8!! 38.Bxf6+ Kh7) 37.Bxf6+ Rxf6 but here it is not clear whether Black can win after 38.Rc1! (my idea was 38.Kd3? Rf2!! -+).
Stronger than 35...Bg4+?! 36.Kd3 Qb6. After the text it is hard to suggest anything for White.
The Engine at least for a while prefers other moves, but the text is certainly good enough.
37.Qd3? loses instantly to 37...Bg4+! 38.Kd2 Nxe4+!; After 37.Nc4 my main idea was to continue 37...Nxe4!? 38.Qxe4 Rf4 39.Qxf4 exf4 40.Bd4+ Kh7 41.Rc1 Bb5 42.Kd3 and here White is firmly lost: for example, 42...Qa2 should win a piece for Black (42...Qa3+!? can be even stronger).
Or 38.Kd2 Qa5+ (for example) and wins.
38...Qxa3+ 39.Qc3 Qxc3+
I did not expect that White would try to resist, being two pieces down. After 39...Be2+ 40.Kc2 Qa2+ 41.Kc1 it is not hard to see that 41...Nxe4! decides, so it could have been a shorter win under the circumstances.
40.Kxc3 Nxe4+ 41.Kd3 Nxf2+ 42.Ke3 Nd1+ 43.Kd3 Nb2+ 44.Kc2 Na4 45.Ra1 Rf2+ 46.Kb3 Nc5+ 47.Kc3 Bf5 48.Ra8+ Kg7 49.Rd8 Rc2+ 50.Kb4 Rb2+ 51.Kc4 Bd3+ 52.Kc3 Rb3+ 53.Kd2 Bxb5 54.g4 e4 0-1
