Perpetual check anyone?
Opponent is losing, keeps putting me in CHECK

perpetual check isn't rude or cheap. often it's the best available move for a player to make in their situation. are you honestly going to say you would want your opponent not to play their best legal move?

Don't feed the (very obvious) trolls,
Not a troll. Just an idiot. See his game against piterak.

If you "clearly are winning" then set him mate and take the win. If you aren't able to do that then accept the draw or the loss.

Even running with your premise, this post is still not worth responding to. The username, creation date, and "come hither to teach the woefully uneducated" posting all reeks of bad trolling, though.

Parfois, la partie d’échecs ne s’achève pas sur une victoire, mais sur une partie nulle. Il existe 5 manières d’arriver à une telle situation :
- Le jeu aboutit à une impasse quand l’un des deux joueurs ne peut effectuer de coup légal à son tour de jeu, bien que son roi ne soit pas en échec. C’est ce qu’on appelle le pat.
- Les joueurs peuvent se mettre d'accord pour faire nulle et arrêter de jouer.
- Il n’y a pas suffisamment de pièces sur l’échiquier pour forcer un mat (par exemple: un roi et un fou contre un roi).
- Le joueur peut demander la nulle lorsqu'une même position est répétée trois fois (mais pas nécessairement trois fois de suite).
- Cinquante coups ont été joués sans qu'un pion ait été déplacé ni qu'une capture de pièce ait eu lieu.

For the above, I would suggest Google translate but it is not very good in specific domains
Tu put it simple:
-stalemate is when the player whose move it is does not have a legal move
-draw offer accepted (anytime)
-no mating materiel left on the board (e.g.: two king and one bishop)
-same position occurs 3 times (not necessarily in a row) and you request the draw on your move
-50 moves without a capture or pawn movement

lol i forgot that thing existed thanks

It's a possibility to repeat, so... It's okay for him. But it's Clear it's a poor player to use this kind of tricks.

No but the game has to be interesting and aesthetic
ChessieJackson2010: And you are very lucky! Sometimes, we have lots of pieces and the other guy has King, Queen, Knight and a few pawns. More, he offers the Queen and wins with a lonely Knight and a few pawns. He doesn't respect our material advantage!

If it has happened 3 times or more - in the same position - press 'Offer a draw' and it will declare a draw by repetition.
This! But also not it is the same position reached 3 times with the same person having the move each time and with no changes in the ability to castle or capture by en passant.
I had likely situation once. Drawish endgame with only 4 pieces on the board: K+Q vs K+Q without pawns. My opponent made carousel of checks around my King with intention flag me on time. He lost connection and lost the game. Chess Karma is a b*tch
