(1) Renna,Joe (1304) - Kern,Jack (1246) [E61]
USATE Parsippany, NJ (4), 15.02.2009
[John Moldovan & Rybka 2.3]
E61 King's Indian Defense
Instead of advancing his attacked P to d5 and giving the enemy his desired Benoni formation, Joe prosaically protects d4 with a developing move. [3.e3
, which aims for 3...cxd4
& a Panov Caro-Kann, is another way to play.]
[A solid choice. The space-gaining 4.Nc3
is more ambitious but more demanding.]
/\ Be2 or even Bb5 (following 5...cxd4
- another Panov line).
At d3, the B interferes with the Q's watch over d4 & is at risk. Trust me on this one. I've been playing similar positions in the Symmetrical English for 18 years.]
Black can yield the B pair in exchange for play against d4. For example : 7...Bg4
, investing a tempo to avoid the pin, also seems wanting as 7...Nc6
threatens to win a piece & the game.]
was more consistent; but Kern's selection does improve upon the 9...Nf8
of Bezler - Eiler : Austria 1999; where 10.dxc5
would have been +/=.]
Diagram White opens the diagonal for his QB & tries to limit the scope of Black's.
[Closing the position hurts Black's clerics more than the Bb2. >=11...e6=
looking to free the Bb7.]
[This strengthens d5 but makes White's light-squared B as bad as Black's. >=12.Nd2+/=
although the thematic ...f5 or ...b5 break would still be far away.]
This delays or stops Black from redeploying his dark-squared B.
[This doesn't help the B any. It will be a spectator here, too. Again >= ...Nh5 or 13...h6
Stepping out of the pin.
/\...Nf4 was still best.]
would've restored the balance.]
Black corrects his errant 13th.
[This exposes Black's K & asks for trouble. He should've played 26...Nf6+/=
; or 26...g5+/=
Threat 30.g3 Qe7 31.Rh5 29...Ng5
Rybka 1.41/20 ]
[This seems to be the losing move. >=29...Ng5+/-
[Tripling against f7 is natural but 31.Qe3+-
was even stronger.]
was a better try.]
The Dame isn't safe here. She should gone to d8 instead.
This vacates f5 for the N, threatens to fork the royal couple & starts focusing on h6 which cannot be successfully defended.
[This loses another tempo & makes Renna's attack overwhelming. >=35...Kh8
/\ 41.Qh5+, etc.]
was best. The unnecessary R check makes White's mop-up more difficult but the victory is still at hand.]
The Rg6 is overloaded.
Black resigns. 1-0
