well by move 29 you were not at all in a winning endgame, white just had too many pawns. You should have been happy to get a draw from that position
Tough end game ends in draw
after you grab the A pawn you can trade rook for pawn if white pawn gets too close to promoting
after that you should be able to get your pawn to promotion square and win
problem was that you didn't have rook in a good position
rook can't do anything on b7 or b8 except trade for pawn so that opponent cant get queen
b2 good square for rook it gives rook more space to maneuver and attacks a pawn
instead of 45. Rb5+, i would have just ran my king over and won all the kingside pawns, and then moved my rook behind white's c-pawn
42. Rb5+
move 45 was Kg4

oh yeah i'm dumb lol
I mean I hung a full room in rapid today sooooo
so you hung your "room" on the top of your house while playing rapid today?
ROOOK AUTOCORRECT!!!! 😡😡😡😡😡

No, I think he meant to say room. You don’t get “whole” rooks.
... I mouseslipped a rook in a rapid game when I could've hit 1800 (I was up a piece) and now I'm so look tilted so please don't troll me...
What could I have done differently to prevented a draw and win? Tough draw to take being up material.
