Sometimes, if you are nervous, it could actually turn out to be a manifestation of your exhaustion. The point is that any setback is bad, but if you see it from a perspective, you'll recover.

I think an important lesson from the game is that once you have made a move, you cannot take it back. You really have to measure your decisions. You think a lot. You evaluate your choices very carefully. There's never any guarantee about what's going to follow once you have made a decision.

If revenge motivates you, go for it! But the main thing is to set your game in order.

In the knockout tournaments, it's futile to prepare for a grand finale. You may have worked out many strategies for the final. But you may lose in the first round itself.

Sometimes an opponent stops breathing, and you realise something drastic has happened and they are trying not to let on. Or they go quiet, or they get fidgety. After a while you pick these things up and become more alert to them.

In chess, knowledge is a very transient thing. It changes so fast that even a single mouse-slip sometimes changes the evaluation.
