Stockfish resigning

I tried to make a long chess game, so I would check the black king and every 50 moves I would take something to prevent a draw. But on move 151, the bot resigned... Is this normal? The bot has never resigned against me before this. lichess.org/jqCay8KXx1L4

yes , is normal . computer cant play more movements of 151 here in lichess.
at least I saw that in a post a while ago

Oh thanks! :) I didn't know that. Then a good way to win a drawn position against stockfish is just to play on until move 151 and the engine will resign 😂
