(2) Moldovan,John (1797) - Mazzillo,Pat (1353) [A16]
21st Kenilworth CC Championship Kenilworth, NJ (1), 12.01.2012
[Moldovan & Houdini 2.0]

G/85+5 A16 English Opening Anglo-Gruenfeld Variation

1.c4 Nf6 2.Nf3 g6
[In last year's Ellner Memorial, my opponent played the weak 2...d5?! ]

3.Nc3 d5 4.cxd5
[4.d4 & a Gruenfeld was considered.]

4...Nxd5 5.Qa4+
! Salceanu in Corr Database 2011 Diagram [5.h4 is a more offbeat option.]

[For 5...Bd7 see my games against "adingod" (STC Championship 2005) and "GMChessy" (STC Gauntlet 2008).]

I thought for a long time here - probably longer than for any opening move I've ever played otb - but my records indicate I had made the very same move against the same opponent before!

[>=6...Qd6 7.Nxc6 Qxc6 8.Qxc6+ bxc6= as in Gelfand-Svidler : Dagomys 2009; In CBM 90, Postny (whoever he is) claims 6...Ndb4 is "the best continuation" but 7.a3 Bg7 8.axb4 Bxe5 9.b5 Nb8 10.d3 /\ Bh6 10...Bg7 11.g3 0-0 12.Bg2 gives White an edge.; 6...Bd7 7.Nxf7! Kxf7 8.Nxd5+/= ; and 6...Nb6?! ? Ribli, Postny 7.Nxc6 Nxa4 (or 7...bxc6 8.Qxc6+ Bd7 9.Qc5+/= ) 8.Nxd8 Nxc3 9.Nxf7 Kxf7 10.dxc3+/= (Krasenkow - Azmaiparashvili : Groningen 1997), both of which drop Ps, are also wanting.]

[>=7.dxc3+/= ]

This avoids doubled Ps but gives me the B pair and an advantage. [7...Qd5 8.Nxc6 Qxc6 9.Qxc6+ bxc6 would have re-established the balance.]

8.Nxd7 Qxd7 9.Rb1
[This unconsiously improves upon the 9.e4 of our 2008 Kenilworth Blitz game.]

This is okay but weakens Black on the a4-e8 and h1-a8 diagonals. [9...Rb8 10.g3 Bg7 11.Bg2 0-0 12.0-0 b5 13.Qa3 Damljanovic - Prada : La Coruna 1998 13...Rb6 was an alternative.; but not 9...0-0-0? 10.e3+/- ]


This loses a piece and the game. [>=10...Na5 11.Qxd7+ Kxd7+/= (H. Olafsson - Kekki : Aabybro 1989 & Lindenmaier - Pomm : Wuerttemberg 1993) was right.; 10...Qd5?? 11.e4+- ]


A tactical defense to the double attack? No!

12.Qxe5! Qxh1
[The 12...f6 intermezzo doesn't win the Exchange, because I have 13.Qb5+- saving the R and forcing a trade of Qs. Pat must have missed this counter-intermezzo when choosing ...Ne5 over ...Na5.]

What a wacky position! The Qs on KR8 are the only pieces off the back row.

[>=13...h5 but Black wants something, rather than nothing, for the piece.]

This brings my Q back into play and stops Black from castling... [.. But the engine says 14.Rb4 was best.]

This drives my Dame to a better spot and gets his R pinned. [>=14...e6 ]

15.Qa4+ Rd7

Ignoring the irrelevant a7P, I look to trap the enemy Q with 17.Rh4, 18.Qc6 and 19.Rh1 or mate Black with 17.Rd4 and 18.Qxd7. If my foe defends against these threats, I can be happy with exchanging Qs or Rs.

This covers d4 and hits my R... [... But >=16...Qh1 17.Rd4 c6 18.Rxd7 Kxd7 19.Qxa7+ Ke6 20.Qxb6 f5 though the 2nd player would then be a B+P in the red.]

17.Rh4 Qg1 18.Qc6
[>=18.Rxh7 -- /\19.Rh8 -- 20.Qe4 -- 21.Qxe5+ Re7 22.Rxf8+ Kxf8 (22...Kd7 23.Qd5# ) 23.Qh8# ]

[>=18...h5 19.Rh1 Qxh1 20.Qxh1 Bd6 ]

This forces the Qs off... [... But much >=19.d4 /\exd4? 20.Re4+ (20.cxd4 Bb4+ 21.Bd2 Bxd2+ 22.Kxd2 I stopped analyzing here 22...Qxf2 (22...Qxf1 23.Re4+ Kf8 24.Qf6 & # in 3.) 23.Bh3 f5 24.Qe6+ is good, too.) 20...Be7 Again, I looked no further. (20...Kd8 21.Qa8# ; 20...Kf8 21.Bh6+ Kg8 22.Re8+ Bf8 23.Rxf8# ) 21.Qf6 Qxf1+ 22.Kxf1 Kd8 23.Qh8+ Bf8 24.Qxf8# ]

19...Qxg2 20.Bxg2 Ke7
If Black tries to save the h-pawn, he drops an Exchange to Bc6-xd7.

21.Rxh7 Kf6 22.d3 Be7 23.g4 g5 24.Be4 Bf8?
[>=24...Rd8 25.Rh5 Rg8 26.Bh7 Re8 27.Bxg5+ Kg7 ]

And with the g5P about to fall, Black resigns Time left - Moldovan 38:51, Mazzillo 35:40 Time used - Moldovan 48:14, Mazzillo 51:25 Longest think by White - 13 minutes for 6. Ne5 Longest think by Black - 8 minutes for 10...Ne5? 1-0
