We start back next Monday! We have a lot of fun events planned for 2015, so tell all your chess playing friends to get to LCCC!
Now a game from our league. Special thanks to Gene McClure for running it thru Rybka and adding his notes. I ran it thru my Igor3000 also (see I3 notes).

10.Ne2?!
Gene: Vince said after the game he was glad I
offered to trade my dark-squared Bishop, and I agree it could have helped
defend f4 from his incoming Knight.
Rybka gives 10. a3 Bxc3, 11.Bxc3 0-0, 12.Re1 Bd7 (+0.3).

R:
Black has a cramped position I3: Not that cramped (.1). If Black had castled
last move, the game is EVEN.
12.c4?!
(= Rybka)
Gene: Rybka gives Ng3 or Qc3. I agree it would have been preferable to put
the question to the h5 Knight with Ng3 at this point, avoiding some upcoming
questionable defensive moves.

I3: A blunder! Castling was the move
to shut down all counter play. Now after Kd2, Whites a1 rook now can come in to
help out. (-2.7)

34.Qxg2²] I3: (-2.6)
Gene:After 33.Re1?:(-2.0 Rybka).Two other moves: (1)
33.Ng5! removes the Black Bishop threat to the White Knight while also forking
the Black Queen and f7 Pawn. Black can
then play either ..Qg6 defending f7 (+0.6), or ..Qf4+ exchanging Queens
(+0.8).(2) A club observer suggested 33.Rg1? after the game as it appeared
White would win the exchange, but Black quickly obtains a Knight and two Pawns
for his Rook, and the White King is left open to repeated Queen checks: 33...Bxh3, 34. Rg8+ Ke7, 35.Rxa8 Qxc4, 36.Rg8
Qxd5+ (-2.5 Rybka). I3: after 33. Ng5, see the mate threat.
33...Qf3? forfeits the advantage [33...Qg4 34.Rg1 Qxh3
