The delicate position, coming from out of nowhere. White is offering the pawn on e4 and is looking to then sac on e6, gaining attacking tempo.... but is this sound?

According to Fritz, taking was good for Black, and although White can take on e6, Black shouldn't panic and simply develop the sleeping Knight on b8

There is no need to take this Bishop.... Nc6 here and Fritz scores Black at -1.01

? But taking here actually swings the point around in White's favour

Here, Fritz suggests f4-f5 is best for White and scores the game at 2.87

? However Qd4 is a mistake... saccing with Bxg2+ is now the best move for Black, as then Nc6 can be played, hitting the Queen thus forcing her away from protecting the knight on g7

This was missed by both players, instead Black feebly tries to defend the position

This becomes futile, Black is losing lots of material and later tries for a swindle, with no joy

Purely to pull the Queen away from the f-file... there is however no perpetual, White can defend easily enough

This was 7 moves too late!
