Round 5: Riordan-Slive 1-0

Charles Riordan

The players follow 13 moves of theory which, unfortunately for Alex, lead to a position which is much better for White. In a difficult position, he misses a Zwischenzug and rapidly goes down to defeat.

[The psychology behind this mistake is understandable. Black realizes that he is going to have to play Kf7 and wants to make sure queens are off the board before he exposes his king. Based on his facial expression during the game, Alex realized that the e6-pawn was coming off with check just after he captured white's queen. Interestingly, Fritz considers 14...Kf7!? roughly equal]

My apologies Charles, but I can only work with what I can find on the net. If you would like, please feel free to send me a digital photo you prefer.

Since I only post pictures of the game winners directly on the page, you do have an alternative though probably not a particularly palatable one.
