I guess that mindfulness and compassion, are not the real key to mastering chess. Chess is a lot about visualization, knowledge and patterns. What you can call mindfulness in chess is more like concentration and mechanical valuation of position. But mindfulness in Buddhism is (IMO) ability to observe even the slightest bodily functions and sensations to understand, how they begin and end to see the they are not I. So one shouldnt get distracted by them.

Developing Ability to win at Chess ~~ Generating Mindfulness & Compassion


I don´t think that being in a compassive state will help to win, you need to have the motivation to fight.
Otherwise if for example you are pawn less or with a worse position you will think: "i´m lost" and stop really trying to win, ok, the evaluation could be true, but you should even try to play.

I think you are seeking ways to increase concentration ability. Viktor Korchnoi practices Ananda Marga yoga and meditation.
Hoping your opponent doesn't see your attack is not a reliable method of winning. If he doesn't, good for you, but you need to enforce your assault so it works out regardless.
As for compassion, be compassionate before and after the game. During it, be ruthless for all I care, so long as you are not breaking rules or being rude.

Here is an audio about a topic which is highly relevant today:
Being at Peace in a World of Conflicts

Are chess players interested in what the Buddha said should be done by one who walks in the way of truth?
How does what Buddha said relate to "developing ability to win at chess". I mean, did Buddha even know how to play chess, let alone play it well?

Mindfulness in Meditation is awareness, and awareness is understanding, and understanding everything on the board is certain victory.

Awareness is understanding? Well, I suppose if you stretch the definition of awareness to the doctoral level.

Mindfullnes - yes, meditaion - yes, yoga - yes, but compasion = no. Compassion will make you not having the fighting spirit that you need to win. You sit there at the board and in front of you there is a human being that suffers from your moves. He is nervous, tries his best, and yet your moves are coming after him, setting him under pressure and finally crushing him. You think you will play better, when having compassion in this situation ? If you feel compassion, you'll either give him willingly a win or draw or you will do that on a subconscious leves by making a blunder. A peaceful compassionate mindset does not go well together with chess (=wargame). You have to defeat your adversary and not having commpassion for him, because he will not hesitate to defeat you whenever you show a weakness.

The Internet’s Own Boy is a great new film about the internet prodigy Aaron Swartz. We talk with filmmaker Brian Knappenberger about the impressive contributions of the young man who ended his life in January, 2013 while facing heavy-handed prosecution for a minor offense.

It should be common knowledge among chess players that "... playing 'hope chess' is losing chess."
I agree wwith IM Jeremy Silman when he points out that chess is all patterns. In order to become a master one must learn these patterns, and the only way to do this is through rigorous daily training, going through hundreds of thousands of master games quickly on a real board, studying masters' annotations slowly, and simply matching yourself against stronger and stronger opponents all the time instead of being a "... big fish in a small pond...."
I believe all areas of philosophy help to maintain this level of discipline, so The Buddha's teachings apply here as they do in all aspects of life.

So what is there to do?
please take < 3 minutes to listen
just listen and breathe.
That's it.

Becoming a Master at Chess is to learn and apply the art of Objective Thought. When we move is it about knowing we are increasing our dynamic use of force, or is it a matter of 'hope he won't see it' most of the time?
