Tuesday Night Marathon: Status after round 3

I decided to give the Tuesday Night Marathon another go even after my heart-breaking finish in my last attempt. I am 2/2 as white so far which is slightly out of the ordinary for me lately, but these games were both playing down so we'll see how things go in future rounds. I'm 3/3 after 3 rounds overall, this tournament is one of the few FIDE-rated events in the bay area so I figured I should be playing in it with any attempt to get more rated games, starting next round I should get a crack at some of the stronger opponents, I just need to keep winning like I did last time so I can keep playing them. I would say my nicest game so far was a quick win in round 2 where my opponent played an inaccurate move order in the opening which I responded to with the best move and then my opponent overreached a little bit by playing moves which somewhat attempted to refute my opening which was a pretty good sign I would have resources to get a better position. I did, which he followed up by letting his queen get trapped so he had to sacrifice it for a rook and knight, but being behind in development and not having a reasonable place to castle he was doomed and resigned a few moves later. Round 1 I showed an amazing ability to miss the same idea multiple times as part of a tactical sequence to only amazingly see it later when it somehow still worked, I wasn't too proud of this performance, but hey, it got the job done.

Round 3:
This game I played okay, I think I missed some early opportunities to get a very large advantage, but I did manage to go into an endgame with a large positional edge and quickly won a pawn. After this I will admit I played somewhat inaccurately, but then something happened which isn't entirely new to me, my opponent, clearly being the defender and being a pawn down offered me a draw. Now, I will admit, I'm not 100% sure the position was winning at that point, but I'm positive it was not a trivial draw either. I've seen people do this and I think once you're above 1800 it's an absolutely rude and ridiculous thing to do, especially to a higher rated opponent. I even saw my good friend offer a draw to a grandmaster in a 4 vs 3 rook ending from the defending that may have been defensible from the defensible, although I have my doubts, but was certainly no clear draw. But I think any player above 1800 should at least follow this rule: if it is clear that your opponent is even nominally better and it's clear that you have 0 chances to win, do not offer a draw, it does not show your understanding of chess, what it does show is a lack of class. I especially love when these players then after the game tell you the position "was an obvious draw" after they go on and lose the game. I mean it is known that King + Bishop + Rook vs King + Rook is a draw, I expect 99.9% of players to make the defender play it out. It doesn't matter how trivial the drawing technique is by the way for an endgame, let the attacking side offer the draw, you show you understand what's happening on the board that way.
