blitz chess

It's exactly the same as other time controls. If you run out if time, you lose

Understood, But how is the winner decided when the timer runs out ?, that was my question

There are two timers, one for you and one for your opponent.  If your timer runs out you lose.  If your opponent's timer runs out they lose.  The draw is possible, however, if say you run out of time but the other player (i.e. the one with time remaining) cannot deliver checkmate with the remaining pieces on the board.  Note that this does not mean it has to be a forced checkmate.

thanks ChickenWings (what a name - ). I was also researching some other rules online from the chess federation and they were also saying someting to the effect of:

By - Checkmate
By - All of the opponents moves are completed in the allotted time (40 moves)
By- The person who has the most sufficient "mating" material on the board when all moves are made by both parties
So I am assuming with this:
You have to make "all" of the moves required withing the time limit (say 40),
If both parties have made all of their moves, and there is not checkmate, then the winner is decided based on the the whichever person has "better" "mating" material left.

Nice

 Not exactly, but pretty close.

When your opponent's clock runs out, there are two things that can happen:

A draw, or a win (for you)

It is only a draw when there is insufficient mating material left on the board for you:

Scenarios:

Bare king

1 minor piece (bishop or knight)

2 knights (I'm not sure about this one, but I'm pretty sure its included)

In order to win, you must have one of these things:

1 pawn, (or more)

2 bishops, or a bishop and knight

A rook, or above (a queen)

It's not exactly who has better mating material, but if both sides have a queen, whoever runs out of time loses, because there is sufficient mating material for both sides.

I have a feeling that you brutally misunderstood what was written there. It's hard to figure out exactly how.

If you play 5|0 blitz time control, it means that you have your own 5 minutes to spend for the entire game, with 0 seconds added after every move. The opponent has his own 5 minutes to spend. 

The only thing you need to remember is if your timer runs out, you lose.

The exception is when the opponent can't checkmate you with his remaining pieces. This means if the opponent has only his king left, or a single minor piece, or 2 knights, he can't force checkmate, so it is a draw if your timer runs out.

Forget that other stuff you've read. It will only confuse you. That 40 moves is something completely different. It is relevant in OTB classical chess, and it only describes some exact time control where you get additional time after 40 moves played. It makes no impact on the rule what happens when your timer runs out.

Thanks for all of the comments  (nklristic, NZoneX & chicken - waaaangss -), you guys have really broken it down the way I needed to understand -. I am first time chess player trying to learn the game (the correct way). The youtube videos / twitch and other content providers do help, but there are some things that are hard to figure out (even from the official docs). It can be a little confusing but you guys are have cleared it for me.

Thanks again
