[Moldovan & Houdini 1.5a]

#2 of 2 simultaneous games G/55+5 (delay) B40 Sicilian Defense

1.e4 e6 2.Nf3 c5 3.Bd3
The Kopec treatment against ...e6? It's playable but there are better options: [3.c3 ; 3.d3 ; & 3.Qe2 , for examples.]

3...Nc6 4.Nc3
[4.c3 /\ 5. Bc2 usually follows Bd3 but here 4... 4...Nf6 (or 4...d5 ) 5.Bc2 d5 , as in Van Dyke - Moldovan : Springfield 08/05/2001, gives Black a good game.; ?4.e5 Qc7 5.Qe2 a6 6.0-0 Nge7 7.Nc3 Ng6 8.b3!? Ngxe5 9.Nxe5 Nxe5 10.Bb2 BRABRU10 - Moldovan : G/30 ChessJam.com 04/11/2010 10...Nxd3=/+ ]

4...a6
[For 4...Nf6 see Azzarello - Moldovan : Checkmate Championship 2008]

5.b3

5...b5N
[5...Nb4 6.Be2 d5= was played in Perez - Hernandez : Las Palmas 1996.; However, continuing in Taimanov-style, with 5...Qc7 6.Bb2 d6 7.0-0 Nf6 is probably best.]

6.Bb2 Bb7 7.e5 Nge7
[>=7...f5 , trying to deny White the e4 square.]

8.0-0 Ng6 9.Ne4 Nf4
This allows White to sac on f7. [9...Qc7 , putting additional pressure against e5,; & 9...Nb4 were safer alternatives.]

10.Nfg5! Nb4
Diagram



11.Nxf7! Kxf7 12.Qf3 Nbxd3?!
[>=12...g5!= /\13.Nd6+?? Bxd6 14.Qxb7 Nc6-+ & White's Dame is trapped.]

13.cxd3 Bxe4 14.dxe4 g5 15.g3 Rg8
Diagram

Without this move, which enables a possible ...Bh6, Black would be in deep trouble. [An immediate 15...Bh6 would have been bad, due 16.gxf4+/- gxf4? 17.Qh5+ Kg7 18.Kh1+- ]

16.gxf4?!
This lets my Q into h4 and allows my B to keep protecting c5. [>=16.Kh1 Bh6 17.gxf4 gxf4 18.Qh5+ Rg6 19.Rg1+/= ]

16...gxf4+ 17.Kh1 Qh4 18.d3 Be7 19.Rg1
Chris has played very well to this point. The tempo-sac at move 16 being his only blemish.

19...Rg6 20.Rxg6?!
This improves my P structure and makes my heavy pieces superior to his. [>=20.Rg3 Rh6 21.Rg2 Rg8 22.Rag1 Rxg2 23.Rxg2 Rg6 24.Bc1 Rxg2 25.Kxg2 Qg5+ 26.Kf1 Qxe5 27.Bxf4= ]

20...hxg6 21.Rg1 Rh8
Threatening ...Qxh2 mate.

22.Rg2 g5 23.Kg1?
Diagram

A big mistake that goes unpunished. [>=23.Qe2=/+ ]

23...Qh5?
[23...Qh3-+ , putting lateral pressure on d3 and forcing White to cough-up a P, was the right way to offer the Q-trade.]

24.Rg3?
This leaves h2 hanging. [24.Qxh5+ Rxh5 25.f3=/+ was required.]

24...Qxh2+ 25.Kf1 Qh1+ 26.Ke2?
This keeps material on but White won't get any play on the K-side and he can't survive on Q-side. [Going into a P-down B-ending with 26.Qxh1 Rxh1+ 27.Rg1 Rxg1+ 28.Kxg1-/+ was the only try.]

26...Qb1 27.Bc3?
[>=27.Bc1 ]

27...Qxa2+?
This succeeds... [... But >=27...Rh1 , threatening 28...Qd1#, was much stronger.]

28.Bd2
Diagram



28...c4!
This is better than taking on b3. Why bother with small fry when there is bigger fish to catch (the pinned B & vulnerable K)?

29.bxc4
[29.Rg1 Bb4 30.Rd1 c3 was no better.]

29...Bb4 30.Rxg5
This allows mate in 3 but White was lost, regardless.

30...Qxd2+ 31.Kf1 Qe1+ 32.Kg2 Qh1#
White checkmated. Time left - Constantino 23:38, Moldovan 10:08 Estimated time used - Constantino 34:02, Moldovan 47:29 Longest think by White - 6 minutes for 18.d3 Longest think by Black - 9 minutes for 15...Rg8 With this victory, I clinched the 2nd place and finished with a +8-4=4 record. 0-1
