After a big win in a cash game, I usually focus on my mental state, not just the amount of money on the table.
If I feel calm, keep making good decisions, and the table is still profitable, I continue playing and try to take advantage of the good situation.
But if after a big pot I start relaxing too much, becoming overconfident, or наоборот, getting afraid of losing the profit, then it’s better for me to take a break or leave the table.
For me, the main thing is not the fact that I doubled up, but the quality of my game and control over my emotions.
