Fortress Theory

I was playing a game with my friend and it became a draw by the fortress theory

. However, as soon as we reached the position of unavoidable draw the timer continued to run. The game did not say anything like "draw by insufficient material." I, as white lost on time although i had an extra pawn. It should have been a draw.

well it's not a draw by insufficient material because you have material for win, but yes its a drawn position, next time just spam premoves and hope that you reach 50 move rule by the time your clock runs out or just agree to a draw

According to the FIDE laws of chess, this position is an automatic draw. You do not need to repeat the same position 3 times, nor do you need to play out 50 moves:

"The game is drawn when a position is reached from which a checkmate cannot occur by any possible series of legal moves, even with the most unskilled play. This immediately ends the game."

yes it's a draw, but doesnt your clock still run on chess.com? i might be wrong

Chess.com doesn't always match FIDE.  It's a draw in FIDE but not on chess.com

This is certainly true.

Sometimes on this site, you have to click the "draw" button to actually claim the draw. Like if the position repeats 3 times, the server doesn't always give you a draw until you click draw.

It's also possible (I'm not sure about this though) that the chess.com servers aren't programmed to recognise these kind of draws, where checkmate is impossible to occur, due to a fortress.

The server never automatically gives a draw until it is a fivefold rep. This is the same as FIDE rules.

True.

Yes ,it is draw if you play OTB with a qualified arbiter .

Unfortunately, if you play online, you are lost!!

Then why?

Because, it is quite exceptional and programmers dont care in writing a program to recognize such deadlock positions. 

So, web GUI wont recognize it as a draw and you are lost.

Alternatively, to solve this problem, programmers already introduced pre- move , you just need to move your king left to right 50 times.

In chess.com one premove cost you 0.1 sec, so you need 5 secs to get 50 moves.However in other site, 1 premove cost you 0.01 secs and 0.5 sec is enough for you to claim draw.

Exactly, just stack premoves and you'll get a draw easily.

Plus, if this were your friend, ideally they would agree to a draw if you offered one.

It's where you use quantum fluctuations and advanced maths to predict drawn positions in any number of dimensions.

Also llamonade I was the one playing against cfna. We just wanted to test to see if chess.com would recognise it as an unavoidable draw. However it didn't. This was just for fun.
