(4) Moldovan,John (1811) - Renna,Joe (1304) [A02]
5th Checkmate Championship Springfield, NJ (1.4), 18.01.2009
[Moldovan & Rybka 2.3]
G/40 + :05 delay
A02 Bird's Opening
1.e3
[With at least 3 Whites in the next 4 weeks (between this event & the KCCC), I probably should've opted for 1.e4
& kept my flexible Van't Kruys in reserve. ]

d6N
[We're already on fresh ground. There have been 3 games with 4...Nc6
; 1 with 4...b6
; & 1 with 4...0-0
]
5.a4
With the cheap threat of 6.d4 Bb4+ 7.c3 Ba5 8.b4 Bb6 9.a5 +-, trapping the oddly-developed cleric.
5...a5
A simple way to nullify the elementary plot.
6.Bb2
Bd7!
By going to the long diagonal, the good B will at least partially compensate for his scope-less sidekick.

...Nd5 would've halted my e-pawn & maintained the balance.
13.Rae1
[This is superfluous preparation. >=13.e4
& a slight edge.]
13...Nh7?
Again, ...Nd5 = was indicated.
14.Ba3!
This is even better than it was at move 12 since there won't be any pressure against f4.

21.e4?
[This simply drops a P. 21.Nd4
, as pointed-out by NM Mark Kernighan, would've won one.]
21...Qf7?
[Black should have played 21...fxe4
(Kernighan) & forced White to prove he has compensation.]

[Lining-up opposite the White Q & on the c4-g8 diagonal is asking for trouble. The Ng6 fork was best avoided by >=25...Rfe8

[This thoughtless move throws away most of Whte's advantage. 26.Bc4

[>=33.Re7

33...g5
Now this attempt fails because the e.p. capture comes with check.
34.fxg6+
Qxg6
35.Nxg6
& Black time-forfeited.
With Joe recovered from his cold & me feeling more relaxed, this was a much better game than Thursday's KCCC opener; my many middlegame mistakes (5) notwithstanding.
