Aikhoje played the first moves relatively fast till we reached the following critical position. He then played this move after only two minutes thought. I am sure he thought he was creating a flight square for e6 Bishop when f5 arrives in future. Is there any other move he could have played that could have saved this position. This move was played due to loss of concentration but I cant think of lasting solutions for him. 16. f5! decides the game
