(1) Moldovan,John (1822) - Stoyko,Steve (2247) [E73]
Kenilworth Summer Tournament Kenilworth, NJ (7), 15.07.2010
[Moldovan, Deep Rybka 3 & Stoyko]

G/55+5 (increment) E73 King's Indian Defense Insanity Variation Deferred

1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4
The last time I faced Steve's K's Indian (2007) we discussed the Fianchetto Variation.

4...d6 5.Be2 0-0 6.Be3
[For 6.h4 see Chieu - Pawlowski : Ellner Memorial 2010]

6...Na6 7.g4
[>= the reserved, ...Ng4-stopping 7.h3 ; or the Gligoric-transposing 7.Nf3 but I hadn't essayed the text in quite a while (10 months) and wanted the benefit of theoretically-expert output.]

[For 7...h6 see my 2009 STC Championship win over "chessforlove".]

8.d5 Qa5

Threatening ...Nxe4. [RR8...e6 9.g5 Ne8 10.h4 exd5 Moldovan - "Ghosts" : G/16, Playchess 09/07/2009 11.Qxd5!= ]

[f3 was played previously: 9.f3 e6 (9...Nd7 10.Qd2 Ne5 11.Rc1 Bd7 12.h4 Qb4 13.b3= E. Fernandez - Camacho : Lorca 2006) 10.Nh3 exd5 11.cxd5 Re8 12.0-0 h5= Bouton - Chevallier : Montpellier 1991; ... But 9.Bd2 , feigning a discovery upon the enemy Q (I don't want to move the Nc3 until e4 is over-protected or Black has weakened d6 with ...e6) & looking to gain additional space with g5, probably improves.]

Now 9...Bxc3 10.bxc3 Qxc3 is the threat [If 9...Qb4 then 10.h3!= /\Qxb2 (or 10...b5 11.Rb1 bxc4 12.Nf3 + Nd2 & White will recover the P.) 11.Na4 Qa3 12.Bc1 Qb4[] 13.Bd2 Qa3 14.Bc1 forcing a draw.]

10.Qd2 e6
[>=10...Nac7 11.Kg2 a6 12.h3 b5 ]

11.Kg2 exd5 12.exd5!
[12.Nxd5 Qxd2 13.Bxd2 Bxb2 14.Ne7+ Kg7 15.Rb1 Bd4 16.Nxc8 Rxc8 17.Rxb7 Rc7 18.Rxc7 Nexc7 19.Nf3 Rb8! ]

[>=12...Nac7 13.h3 Bxc3 14.Qxc3 Qxc3 15.bxc3 f5= ]

13.g5 Nac7 14.Nh3

14...b5 15.Nxb5
[>=15.cxb5! Bb7 16.Nf4 Be5 17.Rhd1+/= ]

15...Qxd2 16.Bxd2 Nxb5 17.cxb5 Bb7 18.Nf4 Nc7 19.Bc4 Bxb2

This absent-mindedly hands-over an Exchange & ruins an interesting game. I must have given myself an extra tempo or skipped Black's turn during calculations. [Of course 20.Rab1 Be5 21.Rhd1+/= was correct.]

20...Bxa1 21.Bxc7
[21.Rxa1 Rf7 22.Kg3 was best.]

21...Be5 22.Ne6
[22.Nd3 Rac8 23.Nxe5 Rxc7 24.Nc6 was no better.]

22...Rfe8 23.Re1??
White wants to play Nxc5 but he's overlooking the pin against d5. [23.f3-/+ was required.]

White resigns Time left - Moldovan 33:44, Stoyko 33:19 Time used - Moldovan 23:11, Stoyko 23:36 Longest think by White - 4 minutes for 15.Nxb5 & 20.Ba5? Longest think by Black - 4 minutes for 13...Nac7 [After 23...Rxe6 White can recover the piece with 24.f4 Re7 25.Ba5 Rae8 26.fxe5 but he loses a P. So...] 0-1
