Chess Checks

Certain positions in a game of chess offer some tricky possibilities from which a person can wriggle out of a difficult position or get a winning position from a benign appearing one.

These moves are not the obvious looking ones and many a time, are discarded without giving a moment’s thought. However these moves suddenly appear to come out of nowhere and are termed as tactical shots.

In the game which follows, Black misses one such fine tactical shot by which he could have tried to initiate quite a few exchanges to let the fizz go out of the position. However after missing this tactical shot, it is downhill all the way for Black.

White:  Suat Atalik (2549) –  Black: Kamil Miton (2443)
