FIFA World Cup 2010 goes on with more drama. Brazil lost after an excellent first half, followed by a poor second half, while Ghana could not convert the chance they got at the end of the match. This just shows that nerves of steel are needed to win games; also in set positions (such as penalty kicks) repetition until it becomes second nature can overcome the emotions when stakes are at the highest. One more reason to continue solving puzzles over and over again, no matter how simple or easy they seem. A penalty kick looks like a sure goal; still players are missing them!
It is your turn now, even if the stakes are not as high; however the players involved in this position are World class. Please practice to make it perfect:
a) Analise the position for both sides
b) White to move and get the best out of this situation
Total available points for this puzzle is 20. The answers will be published next week together with puzzle #125.
Puzzle #123 solution:
Canada Day and the end of the school year has probably stopped most of you from solving this brilliant puzzle. It has remain in history as a highly entertaining and educative one after been made public by Ponziani in 1782. Remember there was no endgame theory at the time and chess books were as rare as flights to the Moon. Still I am proud of all 4 solvers who did their best to work out the best solution; to my total surprise this included some very nice alternate winning lines, showing that you guys know a lot more and can do much better than your results are showing so far. See solution for the best answers of the week. Excellent work guys!
