Study openings is important

@Mahith1708 i am sure that you have played many pawn endgames and rook endgames, and have had many instances where you had to decide whether or not it was favorable to trade down to an endgame or to keep the pieces on the board. studying endgames will certainly help you in all these situations and more. The endgame doesnt have to end with a lucena position for endgame study to be useful.

@Le_Patzer83 yes i have played many rook endhgmes and pawn endgame but i play the endgame on principles like cutting of the king rook behind pawn etc

I have played that Morra trap over the board, played one more move 8 Bxf7, and my opponent resigned in tears. Hard to see that diversion coming.
Morra is good for me because Sicilian players all have their pet lines. No way I can learn all of them. So frustrate with something different.

Funny how black players, faced with the Morra, will still try to use their pet line, Dragon, Najdorf, Sveshnikov, refusing to treat the Morra gambit as something new and different.

@sparowe14 Please post that game

@CanaryMelon It was not played on line, but at a tournament in Greensboro about 5-6 years ago. I don't know how to create a game on lichess from a scoresheet. (I could do it on ICC)
However, it's simple. It is exactly the same game as posted by Diego-Alexander with the addition of the finishing moves: 8 ... de5
9 Bxf7 Kxf7 10 Qxd8 1-0

My CAPTCHA was a mate with a pawn.

Studying openings is very useful but only the first 8 to 10 moves matter for U2200 as it's very rare both players will follow theory up to move 15 even in Najdorf, Gruenfeld and Ruy Lopez. If a player rely on Opening principles only, he will be behind in time after 10 moves. He will have less time to play the middle game and endgame.
