(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
[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. ]
[This seems very artificial & will almost certainly saddle my foe with a bad B.
Moldovan - Sherry : G/5+5, Springfield 04/16/2006; or, if Black doesn't want to sac the e5 square, 3...b6
as in (with transposition) Mangion - Moldovan : Kenilworth Summer Tournament 08/28/2008]
[We're already on fresh ground. There have been 3 games with 4...Nc6
; 1 with 4...b6
; & 1 with 4...0-0
With the cheap threat of 6.d4 Bb4+ 7.c3 Ba5 8.b4 Bb6 9.a5 +-, trapping the oddly-developed cleric.
A simple way to nullify the elementary plot.
By going to the long diagonal, the good B will at least partially compensate for his scope-less sidekick.
is more harmonious yet only a marginal improvement.]
[White will soon regret not having P-control of d5. >=9.c4
[This isn't a particularly good spot for the dame but the more natural 11.Bd3
(+ Qe2); or 11.Qe1
are little or no better.]
(found by Rybka) 14...Nxe5
...Nd5 would've halted my e-pawn & maintained the balance.
[This is superfluous preparation. >=13.e4
& a slight edge.]
Again, ...Nd5 = was indicated.
This is even better than it was at move 12 since there won't be any pressure against f4.
would've given White a clear plus.]
was missed by both sides.]
avoiding another N for B swap & covering g7 ahead of Bb2.]
[This simply drops a P. 21.Nd4
, as pointed-out by NM Mark Kernighan, would've won one.]
[Black should have played 21...fxe4
(Kernighan) & forced White to prove he has compensation.]
[This keeps the Q active but >=23.Qd2+/-
, preventing the following, was correct.]
/\ Nf moves 26.e6, regaining the piece.]
[Lining-up opposite the White Q & on the c4-g8 diagonal is asking for trouble. The Ng6 fork was best avoided by >=25...Rfe8
; or 25...Kh7
[This thoughtless move throws away most of Whte's advantage. 26.Bc4
The text threatens to win with 27...Nxf4+ but is foiled by...]
[This loses. 27...Bxb5
was a better try.]
[In time-trouble and realizing that 29...Nd2
would be worse ( 31...Nfe4
), Renna makes lemonade.]
would've offered more resistance.]
[This drops heavy material & makes the mop-up easy. 31...h5
, forcing the Qs off & emerging 2 pieces to the good, settles the matter.) 34...Qxd5+
swindling a half-point.]
was even more decisive.]
Now this attempt fails because the e.p. capture comes with check.
& 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.
