C50 Hungarian Defence and Giuoco Pianissimo (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Be7 5.c3 Nf6 6.e5 Ng4 7.cxd4)

C50 Hungarian Defence and Giuoco Pianissimo (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Be7 5.c3 Nf6 6.e5 Ng4 7.cxd4)

This is one those lines that may not be that good all the way through, 6...Ng4 is a move that creates problems for Black. If it were possible that the knight could continue on taking on e5, then the move Ng4 would have been justified, but because Gluecifer7 could just reply with 7.cxd4 and prevent me from taking the pawn on e5 in favorable circumstances, my knight was very poorly placed at g4. I tried to be clever and played 7...d5, so that I would provoke the move 8.exd6 in reply. Had that worked, I could have taken back with my bishop and if need be, I would have been able to retreat with my knight to f6. Gluecifer7 did not want to allow me to the improve my options, so my opponent played 8.Bb5 instead.

Then I moved my pawn to h5 in order to protect the square h6 with the rook, so that when my knight needs to move, I would have a decent square to retreat to and I could keep my pawn structure intact. Gluecifer7 then played 9.Qc2, which seems like a logical move that threatens to take on c6 twice and perhaps to win a pawn in case that Black does not properly respond to the threat. The threat was not at all severe, since I was able to reply with Bd7 and the position was only slightly in favor of Gluecifer7. The next time when I chose a path to ruin was when I played 14...Qb4.

The queen was moved to b4 in order to add pressure towards the pawn on d4, but it was a rather futile move, since it was replied with Bd2 and my queen had to retreat. Therefore I just basically gave my opponent a free move to catch up on development. The game continued with the moves 15...Qd6 16.Bf4 Qd7 and then Gluecifer7 played 17.Nbd2, after which the position should be roughly even again. It did not take long for me after that to make the game losing blunder, which was 18...Re7.

The move 18...Re7 may seem quite harmless at first, but it was a rather unnecessary move since I was not going to double my rooks on the e-file, nor was I going to need further defence of c7. Gluecifer7 played 19.Nc5 and the rest of the game was rather smooth sailing for my opponent apart from maybe the move 21.Nd3, which was unnecessary retreat of the knight. The knight was placed there in order to prevent the loss of the exchange, but there was a better way to do it, which started with the move 21.Rxe7+. The rook trade would have given the rook from f1 time to move and not be in the bishop's scope anymore.
