Wining tricks for black and white

In this position, white tricked black, and sac queen, but white checkmated black!                                                                                                         

Here,  black has  a better position, because black has a pawn on e4 square!                                                                                                                

It Halloween gambit, in Halloween gambit white sac knight for pawn, but white win a pawn and knight.  If knight will go back to c6 square, then d4 pawn will go to d5 square and it will be the same problem for black
    

Guys, I hope those thricks will help you! 🙏❤

Tricks, sorry for mistake ❤

I have a trick of my own that I use a lot. Can I share it?

I know a very useful caro-kann trick.1.e4 c6 2.d4 d5 3.f3 d×e4 4.f×e4 e5 5.Nf3 e×d4 6.Bc4 Bb4+? 7.c3! d×c3? 8.B×f7 K×f7 9.Q×d8 c×b2+ 10.Ke2 b×a1=Q . Here black has a material advantage, but there is a HUGE problem. Can someone find it?

No one? OK,here : 11Ng5+ Kg6 12.Qe8+ Kh6 13.Ne6+ g5 14.B×g5# cool no?
