Max Dietrich vs. Anton

Q1. Max has just played g4. It look suspicious should we take it?

Q2. A few moves later Max captured Anton's pawn on e4 with his knight. How could Anton have taken advantage of this error?

A1. Anton castled his king onto an open file - always a bad idea. If he takes the poisoned pawn on g4, Max will play Rg1 pinning it to the King. The game continued 15. ... Nxg4 16. Rg1 h5 17. f3 and the knight is lost.
A2. Not learning from the first position, Max captured a pawn on e4 with his knight (he should ahve taken with the d-pawn) Now Max's knight is pinned and all Anton has to do is ATTACK THE PINNED PIECE WITH THE SMALLEST PIECE POSSIBLE !  (Yes, I was shouting.) Because Anton attacked it with his bishop instead of playing the simple d5! He could have just about evened up the score here, but I'm guessing Anton had already given up and was no longer thinking.
