Never give up!!

This is a game that I should not have won. I'm posting it to encourage other beginners like me not to quit even when all seems totally lost. I made some bad mistakes in opening and it went down hill from there. By turn 35 I was down to 3 pawns playing against two rooks and two pawns and my opponent should have easily won. Yet at turn 46 I realised he was relentlessly pursuing mate and not watching or even attacking my pawns. I couldn't have predicted what followed.

If all seems totally lost, if I don't quit. I always got checkmated. As a 1300.

I suppose the point is that over confidence in a winning position can lead to a blunder or two. In this case I should not have been allowed to promote a pawn and it wasn't hard to stop. Maybe at your level that is a lot less likely!

I can't seem to load the game on the Android app, am I doing something wrong? It just shows 1. e4 and no other moves.

yes it is interesting game and you are right 

Fortunately the promotion 50...h1=Q+ comes with check. It was that saving moment for Black.

Sadly 40. Rxh4 is the simplest move I would have played, which many lower-rated players would hesitate to play since the rook would be lost to the weaker pawns, not realising that White is already pieces up,

Your opponent must have laughed in evil fashion when he realised how slow the Black pawns were, until the pawn got promoted on move 50.

I can watch only one move. e4
