Board 1 Time Control: 40/80+15/30... B41 Sicilian Defense Kan Variation (by
transposition - 7.e4) 1.Nf3 c5 2.c4 Nf6 3.Nc3 e6 4.d4 cxd4 5.Nxd4 a6 6.a3!? (?! HIARCS 14's opening book) 6.e4 ∆Bb4 7.Qd3 Holub -
Barta : Prague 1955 6.g3!? Qc7 7.Bg2 Qxc4 8.Bf4 (Friedman -
Bodisko & Friedman - Charmov : correspondence 1975) does not impress. 6...b6 6...d5 7.cxd5 Nxd5 Holm - Sznapik : Nordic Team Tournament, Oslo 1983 7.e4
This is the 3rd time in 10 days that I've transposed from the
Symmetrical English to an Open Sicilian. 7...Qc7 7...Bb7!? Skreno - Likavsky :
Ilichevsk 2002 ∆8.e5N Ng8! was an option. ≤8...Ne4?! 9.Nxe4 Bxe4 10.Qg4 8.Be2 8.Be3! Bb7 9.f3 ∆d5?? 10.cxd5 exd5 11.Rc1 (Barrio - Hernansanz : Eibar 2013) is precise. 8...Bb7 9.Qd3 9.f3 ∆d5? As in the previous note, this "freeing" move is mistaken. 10.cxd5 exd5 Ernst - M. Carlsson : Swedish Championship, Gavle 1982 11.Bg5± (TN) was a good, more solid alternative. 9...d6 /\ ...Nbd7 + either 11...
Ne5 or 11...Nc5. So, White has to find a way to prevent &/or neutralize both. 10.f4 Nbd7 11.Nb3 11.b4 Queimadelos - S. Kovacevic : Pedrido 2004
but I was worried about weakening c4. 11...Be7 12.Be3 0-0 13.0-0
These Hedgehog positions are very demanding & not my cup of tea but I didn't
think a draw-offer was in order. 13...Rac8N 13...Rfd8 14.Rad1 Rab8 15.Kh1 Bc6 16.Nd2 Nc5 17.Qc2 was played in Jacobsen - Nogues : London 1927. 14.a4 14.Rad1 14...Qb8 15.a5 Nc5 16.Nxc5 bxc5 17.Bf3 Bc6 18.g4
/\ 19.g5, dislodging the Nf6 & relieving some of the pressure against e4. h6 We've played well to
this point but have used an inordinate amount of time - 42:24 for me, 49:50
for my foe. Of course 18...Qxb2?? loses to 19.Rfb1 19.Rfd1?! Indecisive. A full K-side commitment with 19.h4 would've maintained the balance. 19...Nh7 Now Black is better. Daniel
Girsh's 19...Nd7 was a good alternative: 20.Qe2 Rfd8 ≤20...g5?! 21.Rf1= 21.Qf2 Bf6 21...g5?! 22.Rf1= 22.h4 Bxc3 23.bxc3 Nf6 24.Qg2 Qa8 25.g5 hxg5 26.hxg5 Nxe4 20.Qe2? 20.Rab1 20...f5? 20...Rfd8 21.exf5 Bxf3 22.Qxf3 exf5 23.Nd5 Bf6? 23...Rce8= 24.Nb6?
24.g5± 24...fxg4?? 24...Rce8= 25.Qd5++- Kh8 26.Nxc8 Rxc8 27.Qxd6 Qxb2 28.Qxa6 Re8? 28...Rg8 29.Rab1? Much 29.Qb5! Rxe3 ≤29...Qxb5 30.cxb5 Bxa1 31.Rxa1 Rxe3 32.a6 30.Qxb2 Bxb2 31.Rd8+ Nf8 32.Rxf8+ Kh7 33.Ra2 Bd4 34.Kf1 29...Qe2?! 29...Qa3 30.Bf2 Bd4 31.Bxd4 cxd4 30.Re1 Qd3
30...Qf3 31.Bxc5 was little or no better. 31.Bf2?! This covers g3
but 31.Bxc5 Rxe1+ 32.Rxe1 Bd4+ 33.Bxd4 Qxd4+ 34.Kh1 31...Rf8 32.Qe6 32.Qc6 Qxc4 33.Qd6 /\ Rb8 32...Bd4 33.Bxd4 Qxd4+ 34.Kh1?! 34.Qe3! Qxc4 35.Ra1 34...Qf2? 34...Qc3 35.Qxg4 Nf6 36.Qg2 Qxa5 35.Qxg4 Rxf4 35...Nf6 36.Qg2 Qxf4 36.Qg3 Qd4 37.Rg1?! 37.a6 ∆Qxc4 38.Rb8+ Rf8 ≤38...Nf8 39.a7 39.a7 37...Ng5 38.Rbd1??
38.a6+- 38...Qe4+? 38...Ne4! 39.Rxd4 Nxg3+ 40.hxg3 Rxd4 41.a6 Rd7± 39.Qg2 Qxc4 40.Qd5? 40.Qb7+- 40...Qxd5+? 40...Qa6± 41.Rxd5+- Nh3? 41...Ra4 42.Rxc5 Ne4 & White has to show technique. 42.Ra1 Now, the win is easy. Rg4 Threat:
43...Nf2 mate. 43.Rd2 Defending. c4 44.a6 c3 45.Rc2 Black resigns.
Time left - Moldovan 28:08 (for 10 moves), Ahuja 27:00 (for 11) Time used -
Moldovan 81:52, Ahuja 83:00 Longest thinks: White - 8:48 for 9.Qd3, Black -
12:12 for 17...Bc6 Game length - 2:44:52 After 45.Rc2 Kh7 /\ 46.Rxc3??
Nf2 mate 45...Rc4 46.a7 Rc8 46...Nf2+ 47.Rxf2 c2 48.a8Q+ Kh7 49.Rxc2 Rxc2 50.Qe4+ Kg8 51.Qxc2+- -> 47.Rxc3! or simply 47.a8Q Rxa8 48.Rxa8+ Kh7 49.Rxc3+- 47...Rxc3 48.a8Q+ Kh7 49.Qe4++- -> Kg8 49...g6 50.Qe7+ Kg8 or 50...Kh8 etc. 51.Ra8+ Rc8 52.Rxc8# 49...Kh8 50.Ra8+ Rc8 51.Rxc8# 50.Qe6+ Kh8 50...Kf8 51.Ra8+ Rc8 52.Rxc8# 51.Ra8+ Rc8 51...Kh7 52.Qf5+ g6 53.Qf7# 52.Rxc8+ Kh7 53.Qe4+ g6 54.Qe7# 45...Rf4 46.a7 Nf2+ 47.Rxf2 Rxf2 48.a8Q++- -> 45...Rg5 46.a7 Kh7 47.a8Q+- 46.a7 a8Q follows. 1–0
