After looking at perrypawnpusher - hicks, 2 12 blitz, FICS, 2014 in the last post, I was playing over Philidor 1792 - Sauron 2005, 3 0 blitz, 2014, when I noticed an interesting contrast.
In the previous game, Black was done in by the fact that all but one of his pieces were on the back rank - a positional concession that had a tremendously negative impact. Here, the situation is completely different: Black can hold off White's attack by retreating - 18...Nh8 19.Kb1 Qd8.
Instead, Sauron 2005 counter-attacked, and lost.
