early and allows black to equalize quickly.} Bxc5 {[%csl Rf2][%CAl Gc5f2] [#]}

this would become a critical issue later on.} a5 $5 {Stops any idea of white

[#] Did black make a mistake? Suddenly, the knight on b4 is pinned. Caleb
ponders for a few minutes belts out...} d4 $1 {While the engine still likes
white, this move has a lot of psychological venom. White may have thought he
was winning a piece, but this move totally disrupts white's forces. It also
frees black's knights for d5 and the bishop on the a8-h1 diagonal.} 14. cxb4 $4

This simple capture not only wins the exchange, but cannot be recaptured and
thus prevents the knights from the d2-square. Black threatens Rc1+ and e2.} 15.

moved his queenside rook and knight. The thematic d4! sacrifice opened up the
position for black's pieces and the position flowed nicely.} 0-1
