What do you feel about players that do perpetual checks when they are losing?

you need to shift your perspective. If your opponent allows a position where you the losing side can land perpetual check, he wasnt winning to begin with. ( he was only winning prior to allowing that possibility to happen).

Just like stalemate is a fact of life in chess, so is the threat of perpetual check. You have to learn to take advantage of it when it is in your favor

Regardless of points on the board, you're never winning when your King can be chased endlessly. Perpetual check is somewhere between checkmate and safety. A draw is the appropriate result. 

As it turns out, the OP has several draws by perpetual since then - and in one instance in 2015, the OP, who was on the materially disadvantaged side, had to give checks repeatedly using the queen to save the draw.

Giving perpetual checks is what you are supposed to do if you are losing. 

All these fiery posts where beginners moan that stalemate, winning on time, draw by repetition, etc. are all somehow wrong..... I don't remember any of these ridiculous discussions taking place in an actual chess club.  Chess.com seems to have a gigantic block of newbies that think the rules should be changed to suit their first impressions.  It's like being overrun by a mob of zombies.

GOOD FOR HIM, HE AVOIDED A LOSS .

I just drew a game with a perpetual check my opinion of them is high right now.

If someone has sacrificed material for attacking chances but can't achieve checkmate, they might have no other choice than going for the perpetual check to avoid a loss. If someone has a winning position but leaves their king without sufficient protection in order to bring another piece into the attack, leaving an opening for the perpetual, why expect the opponent to pass it up and take the loss?

Good players use this trick to avoid losing, stale is better than losing. It perfectly allowed and accepted by GMs. 

It takes Two to tango

yeah the game was terrible but about past move 37 we both have around 30 seconds

and i win on time (anything for a win)

Here's a pro tip: If the can force perpetual check, they weren't losing!

Somebody once checked me 18 times before checkmate... Like bro you're not the TSA

If they have the option to force a perpetual check, then your position was never a winning one - it was a draw.

I'M trying to get a draw in one of my games . . .

I think perpetual checks is the best tactic in chess. There are many powerful tactics in chess, such as fork, pin, skewer, double check, discovered check, etc. These tactics are used to win the game. But perpetual checks is the tactic to smartly make a draw. When a player is down materials, or in a bad position, or may get checkmated in several moves, they can make a draw by perpetually checking their opponent's king, provided there is a perpetual check existing on the board. Also, this mechanism gives the weaker side a chance to make a draw (at least not lose the game). If perpetual check is illegal in chess, then when one side makes a blunder or mistake, mostly they just click the "resign" button. Finding perpetual check encourages them to fight until the end. Also, finding perpetual checks is not easy at all. When your opponent's king is well protected, there's no way for you to perpetually check their king. Sometimes you need to sacrifice some of your pieces to force a situation of perpetual check. This tactic also includes perpetual attack, perpetual threat of checkmate, and all kinds of repetition. By the way, stalemate is a great tactic to make a draw too, because stalemate and perpetual checks are often relevant. When you are playing an endgame, and you know you are losing, then you can force a perpetual check or a stalemate to make a draw.

If the opponent has a perpetual check available, then they AREN'T losing.

One of the best chess quotes of 7/22/23.

This sounds so ridiculous #1 chess isn't won by material I've seen many games where the winner was down 5+ points material it means nothing because you don't play chess for pieces you play to check mate and in a situation where I'm unable to mate but you make the mistake of falling for my sacrifice and allowing me to engage in a perpetual check then you sir aren't winning anything that is a drawn game that you may have been in a winning position of until you made a mistake that cost you the win don't be a sore lower instead learn how to prevent it. Nobody is going give you a game because you were up material if there's a way to draw that's what a skilled player is going to do if he knows he can't mate its part of the game bro has been since it was created
