Omg look at this Black Magic

That is literally some black magic right here xD I didn't even see that until the move I played it o_O Need to share

Nah. Your opponent seemed to lose the defense on g4 by playing 14.Qf2, allowing 14...Ng4 and the tactic. In other words. Qf2 was a blunder by your opponent, and Ng4 justifies it :D Your opponent really should've played something like Bd7 to Add another defender to the e-pawn and to get out of that nasty tactical opportunity.

@Classicler It's just funny how I was about to lose and then this happened ... xD Neither me nor my opponent saw that coming. It's fascinating because the bishop is hidden behind the knight and the diagonal to the king is well protected at the moment. I didn't expect such a pin to be possible.

@SucheSchachfreund Yes it is quite hard to wrap around the tactical sequence because there are many tactics at play:

1.) Before the tactic even started, the bishop was x-raying the d4 square (blocked by the knight), which is a square to consider for a future plan or tactic whenever possible since it lines the bishop up with the King on the same diagonal.

2.) 14...Ng4 forks the queen and bishop.

3.) 15...Nxe3 forks the two Rooks, making it rather imperative to take the knight.

4.) 16...Bd4 pins the Queen to the King, making use of the d4 square which was earlier mentioned to be x-rayed by the Bishop.

At first, it is a little difficult to understand, but tactics with similar concepts to the above-mentioned could appear in one of your future games, so it's always good to recognize these and similar patterns :D

@Classicler you don't need to explain my own tactics to me, I know how it works lol...

Also the d4 square isn't something you would usually consider, as the bishops stays in its fianchetto in most games.

@SucheSchachfreund Oops, sorry about that :(

It seems like you have got ego

@Thecaa ?? It's supposed to be a joke because the pieces are black and I didn't see the tactic it more or less happened by accident as it was a blitz game... what do you mean?

Be6 and exf4 i'd say are questionable. Be6 gets in the way of f4-f5, and it's best to hold onto your center. i think c3 instead of either move would be an improvement. In the position before Qf2, obviously h3 is called for. h3 is used in many positions where f4 is pushed to prevent that very knight jump. from there, white can proceed to reinforce his center pressure and bishop pair, meaning when eventually he opens up the position in the center, he will be at a significant advantage. Black lacks meaningful pawn breaks after h3. Nh5 is trivial, but Black's best bet imo is to play c5 and aim to control d4/ the long dark square diagonal.
