Yes, clearly he would reach draw by repetition well before 50 moves, even if perpetual has never been added.

"Oh, and my game is currently still going if anyone would like to see it. It's the one in the 40+ moves."

You are discussing an ongoing game. I don't think you have benefit of it but you could be punished by the staff. Discussing an ongoing game is agaisnt the rules.

Another word of advice - easier said than done - the excitement of having a won position against a stronger opponent is something that used to lose me a lot of games!  You got away here with a draw, so cheap lesson!

A good player advised me that won positions don't win themselves and converting the win often requires a huge amount of technique, patience and hard work.  Sounds obvious but I was a slow learner!

It's never fun to draw a game you thought you would win. But it seems as if you got a very cheap draw against cew57 in a previous game, so why not just look at this as an equalizer?

Draw by perpetual check and draw by threefold repetition are different things, in the laws of chess.

If you can show the arbiter that you can keep checking the opponent no matter what he replies, you can claim a draw. Alternatively, if the current position has occurred for the third time and it's your move, or it's your move and you can make a move that would repeat the position for the third time, you can claim a draw. Two different rules.

The first is hard to implement automatically, the computer would have to check if there really is no way to avoid the checks (that may in the process chase the king all over the board forever). That is why usually only the three move rule is hardcoded into online chess servers.

In this case Black obviously has perpetual check and could already claim a draw in a real life game, but on here the position will have to be repeated three times before he can claim. Common courtesy would be for White to offer a draw.

Anyway, this is a perfectly normal drawn position, White has let go of the winning position he had earlier. So it goes. Better than missing a checkmate...

Fantastic play by ambach. Although he was in a difficult position he defended as best as he could and then when you made the error (38. Nd7) he pounced. The only thing I don't understand is why the game is still going on. Can someone from staff of chess.com explain - surely it is a draw now because the same position has occured three times?

Why no one claims draw?

Good spot pling.

Why not resign in this position. Black did the hard bit and has really been cheated out of this game.

(I'm only messing majere - that was really great chess - forced all the way)

I agree. Like ambachs endgame - strong play! The previous move: c3 proved fatal to blacks winning hopes. Just like majeres slip at 37.

Win, Lost or Draw the fun part for me is trying to make the best moves i can and get beter each time.  In fact, defending "losing" positions or playing from behind to get a draw can be some of the most fun games.

Well done as White to get a 1/2 point.

You didn't have a winning position if it allowed your opponent to force a draw, did you?

Oh brother rules are rules So thats all there is to it. 

Ok After some thought I would not play for perpetual check Just seems Tacky  HMMMM An intereting question

I think I would put is slightly differently.

Would you like the rules of chess to be changed for all of us? Or may be just changed for you?

Would you argue the same if you did a lot of work etc and your opponent managed to make you stalemate him?

It is frustrating when you do a lot of work etc and then make a blunder but that is your fault not the opponent's. If any grandmaster was losing and could only draw by perpetual check I believe they would take it. The object of the game is to win and if you can't win to draw.

Agree with all. You let him have the perp. It's a fair draw.

You shouldn't feel so bad. You were likely lost after move 15 down the exchange. Back and forth games like this are common. Get used to them.

You're frustraded that you couldn't turn a good position into a win , a win against somebody with a higher rating , even better . Hey your oponent  did well too , instead of loosing he gets a draw  , but he still looses  points you get a few .

 Can you explain what exactly you found wrong with anything I wrote rather than just calling me a twat, or would that be beyond you?

Majere,

on the flip side.....

I had a game recently where having built a big lead, suffered a hallucination that allowed a perpetual check. My opponent obviously didn't know how to claim, and didn't ask me. So we played out the repetitions till he lost on time. I had plenty of time to think about the ethics and decided it was his responsibility to know the rules.

Eventually he suffered a mouse-slip and gave me his Queen... harsh but fair imho!

I once lost a win that way, I was even ahead in material by a queen, but an ingenious perpetual check forced me to draw. I didn't think it sucked the fun out in any way, in fact, I enjoyed the finish because it was a novelty I hadn't seen coming.
