HOW DOES WHITE LOSE THIS GAME????

https://www.chess.com/live/game/2588904620

Greed, and not knowing how to mate.

How does White lose that game? Obviously his last two moves. :)

All White had to do to win the game would have been to check the black king on f4 with ...Qf4+ on either move 40 or 41 (forking Black's king and queen). The queens would be traded off, and even though White would lose the knight, White would still have winning material.

ya big time, I blundered too much, and was left in desperation mode lol .... that opening is too aggressive and I rarely see it backed up by any defence if it fails

 It looks like white was trying to lose, I see no other explanation.

 He missed 36. Qh6 checkmate

Ha! I didn't even get that far...I started at the end of the game and only had to back up two moves!

He delivered 87 useless checks
