Rules for blitz chees

Hi, I'm inreresting in rules for blizt game. I play offen with friends 5' games, and we often argue about the outcome of the game in a situation where someone's flag falls. When the game is draw, and when it is won for the player whose opponent has dropped the flag?

Thank you.

If a player's clock runs out, it is a loss unless their opponent does not have sufficient material to mate. If you're playing by FIDE rules, then if mate is possible by any series of legal moves then the side with time wins

That rule is more than unreasonable because it means that if a player has, for example, a queen, two rooks and, for example, two knights, he loses the game because the opponent has only one pawn with which the "weaker" side's winning position can be formed

I can't find FIDE rules, explained in details for such situation.

I think it's perfectly reasonable, if you agree to play with a clock. And why else would you want to play Blitz? And you can still play with an increment to avoid such losses.

jvuyff is new account played only one game .. how come his rating is >1700 ??????????????????????????????????????????????????????????????????

Poor time management, not my fault

@snovic as already mentioned under FIDE rules it would depend on if a mating position can be constructed or not by any series of legal moves. So if you had only a knight or bishop, it would depend on what material the opponent had (if any)

If you’re just playing with friends then the chess.com

rules may be simplest, lone knight or bishop would be a draw.

Basically, if the side with time can set up the material on the board on a mate, then it's sufficient, under FIDE regulations, as long as the moves to get there are legal.

If the side with time has a lone king, that's insufficient material to mate or win on time, so it's a draw

A king and bishop or king plus knight against a lone king, is insufficient material to mate in general, so as soon as that material is reached, it's a draw

In most cases, as long as the side with time has at least a pawn, there's going to be sufficient material. One exception is if the side that runs out of time has a king and queen and the other side just has a king and knight or king and bishop, since there's no way to set up a mate with that material as the queen will always be able to intercede or take the checking piece.

King and knight for the side without time versus king and bishop is also insufficient.

What about king and knight with time, against king and 1 pawn? I think mat picture can be achieved only with pawn at a or h kolumn and if he isn't moved , and with bishop is always draw.

And, I think this is last question, what if you set mat picture, and in retrograd analysis can be proved position can be achived?

Under FIDE rules the side that flags loses, as a mate can be constructed with a knight against a pawn (pawn promotion to a knight etc.). There is a famous incident Socko vs. Foisor with KN vs KN where the arbiter thought it is a draw, but Socko appealed and won.
