Josh Waitzkin on trading pieces ('the art of the trade')
Rewan Demontay and I have already edited the above question. So far there are only 2 re-open votes (vs the apparently only 1 close vote needed. so much for 'Chess Stack Exchange doesn't see much questions per day or traffic, so we don't have the luxury to close questions', though I guess the context is different...which might be seen at the end of the sentence...)
Please make suggestions to further improve question, so it can be re-opened.
