The 2013 Alekhine Memorial chess tournament game between the young exceptional Chinese talent, Ding Liren, and Armenia's longtime #1, Levon Aronian, was an excellent example of positional chess. We can clearly observe in this game how a space disadvantage invariably influences the relative value of the pieces. I believe Ding's 28th move had been played with a significant amount of calculation behind it. Aronian's reply to it netted him the exchange, but a serious lack of space persisted. The finishing tactical sequence was both stunning and accurate right to the very end.
