OTB game - should I have continued as Black?

I played Black and received a draw order, and took it. Only afterwards, I came to know that my opponent was rated 100 points lower than me. Then I regretted having accepted the draw, and regretted not knowing on beforehand about the rating gap.

I could have played on, and go to the bottom testing his tactical and end-game abilities.

The best way to tell, is to hit the finish against computer button, and see if you could play it out.  But other than that, taking a draw here was a very resonable option. 

Draw was best. White is actually winning a pawn. ...Ba6 Nd2 wins.

True.

Wait, you received a draw ORDER? Must have been a rather inexperienced TD.

what time control are you in? classical / rapid?

i once got a drawn KRP vs KRP ending in a classical otb tournament, my opponent offered a draw and i rejected it because i'm pretty confident that i could win the endgame. i blew it pretty fast and lost. and only after the game i knew my opponent was a NM.

the lesson is always investigate your opponent rating before the match

Damn spelling check 

The draw was a gift.  You didn't play that great and could benefit from analyzing the game.  

The OP most likely learned English as a second lanquage. He almost certainly meant draw offer.

Caesar49bc:  Are you sure it's his second lanquage? 

How about, we all just relax a little with all the grammar correction.  

I am telling that sometimes my phone is 'correcting' my text and, while I intended to post an English word, it replaces it with a known Dutch one.

Anyways, thanks that chess.com is not only offering chess lessons but also English lessons.

That's illegal now. It's advice.

But white is much better.

White will soon be up a pawn.

And therefore, white is much better. I hesitated to say that white has a won game, because it's an edge pawn.

Edge pawns are outside passed pawns. It’s a winning advantage.

I'm sorry but I didn't bother looking, because the question was whether black should have played on. Incidentally, some of us were looking at a topic where one side could have created two outside passed pawns, one on each side, and still it was a draw, although it was K+R vs K+R+p+p. The only possible win is if the superior side could have created a passed f pawn.

This is the thread. There was some discussion as to whether Stockfish discovered a winning solution that was over 40 moves deep but it wasn't demonstrated. It may be there but probably beyond anyone except top GMs if it is.

I was only reacting to the apparent claim that all outside passed pawn advantages are winning. I'm very bad at endings unless I happen to be playing very well, when I'm extremely good.

Then it's obviously a sign of natural brilliance.
