…is that they can’t really be played unless you save time for them.
I saw his 28..f4 coming as it was his only desperado to try, then I realized I could ignore it and play 29.Nd3 anyway, and after 29..fxe, 30.Ne5+ NxN, 31.RxRc8 e2, Re1 (and showed it after the game, kicking myself that I didn’t play), but I didn’t want to play too presumptously and felt that 29.Kf2 would be a safer endgame win.
I saw his continuation as well, after I played Ke2, but felt I could still win (and it’s still winning, yes).
After the game, I felt that 33.Nc6 is where I went wrong, and 33.Nb3 does win (I had only looked at 33.Nc4 during the game), but it’s a tricky win because 34.Rc5, trading rooks is the only winning continuation.
The natural looking 39.Kd3? is the move that throws away the win, and this is unfortunate since a second time-control would have saved me here as I only needed to get this last idea of 39.Kf3, and I would maintain the win (and have time to win the won game).
After this point, I was in extreme time pressure, such that I saw that 44.Rxb4 would allow him to cutoff my king with his rook, but I didn’t want to check his king toward my pawns, and having have 44 seconds or less at this point, I just couldn’t make a rational decision, which also explains my moving my king to the a-file.
This game should have been a win for me, but the ridiculous moves brought about by my time-pressure proved decisive. It’s my own fault though as I wanted to prove to myself that I could win it the endgame way, and should have kept bolting out the tactics with 29.Nd3. He spent a long time on 29…f4, and I hadn’t finished calculating it when he played it, so I over-respected his decision to play it since it is a move which either works or is a blunder, and he hadn’t tried any real shots of his own during the game up to this point. With more time, I would have simply played 29.Nd3.
I do realize that online chess is online chess, and OTB chess is OTB chess when it comes to time-pressure, but I was pleasantly surprised to play this game in just 2 min, 11 sec:
I spent 21 seconds finding the key move of the game …6.d5!
Speaking of time-pressure, I saw Life Master Brian Wall’s time-pressure meltdown/loss to Joe Ford <1900 from a superior rook endgame position, overlooking a move where he needs to guard his pawn with a rook, sort of a ??? move for a Master. So I know that I am not alone in time-pressure "the (sea-diver) bends" type reactions.
