How to avoid stalemates in winning games?

The most common draw I have is stalemate due to no legal moves which is because all I have is a rook and a king and I’m trying to corner the opponents king but I end up putting them in a spot where there are no legal moves forcing a draw which is the worst feeling in the world.

I have gotten a checkmate a couple of times in this situation too but I wanna learn how to get one every time since this is a common end game for me and it feels like throwing a winning game.

How do I avoid this?

Inaccurate. If you give checks all the time, this can happen. Ok, but it's true that a stalemate cannot happen as a result.

Takes some talent. You're managing to find one of 68 positions in a total of 399,112.

Not possible to checkmate giving checks all the time in KR v K unless it's mate in 1. You don't need to corner the opponent's king at all - there are mates everywhere on the perimeter. 

Usually faster to just push the king to a side - any side - as quickly as possible when mate becomes straightforward.

E.g.

That's assuming you don't stalemate. Just make sure you're not going to stalemate before you move or work out where the stalemates are. They only happen with the opponents king in the corner and there's only two types, so you don't even need to think about it unless the king's next to a corner.

But your chances of needing to mate with KR v K are about as slim as finding yourself in KBN v K, because your opponent will invariably start with 1. Resigns.

Search Youtube for checkmate with king and rook so you'll understand how to do it, then practice that scenario against a bot.

Better still work out how to do it. If that fails play it as the lone king against Syzygy and see what it's doing to you. Then practice it against Syzygy because the bots or Stockfish are likely to be flaky on accuracy.

Yes, good. Why read the opening post, it is just a waste of time, you can crack a lame joke without it just fine.

Always look to see if the opponent's King has somewhere to go. Don't move until you see it. Try to box them in and push them to the corner. The last move is usually the tough one.

I would say just make sure every move puts your opponents king in check

This wins the prize for the worst possible answer, congratulations.

This is what happens when you don't even bother to read the opening post.

I may have misunderstood the post but aren't they asking how to avoid stalemate when using the rook and king to trap the opponents king? Would making every other move a check not work? I haven't been in this scenario before but It should work no?

Always putting the opponent in check may avoid stalemate, but that often won't be enough to avoid a draw.  Constant checking may end up in a draw via the 3-repeat rule or the 50-move rule unless you use some non-check moves to position your pieces correctly for the checkmate.

I probably should have clarified about avoiding the repeated checking rule but you are right.

I try to leave them with at least one additional piece, rather than completely wiping them pout

I started leaving them with a Knight, they are the easiest to avoid and can pretty much always move. The King/ Knight versus King checkmate is just something you have to practice. It's not hard, I figured it out on a board, but I should look at the videos.
