Post subject: | Another game against Queenchess |
Dedicated readers will recall my mild moaning about mismatches in a recent BGA tournament, and the hope that the upcoming Welwyn Garden City tournament would provide more even (not "even more") matches. In the event, the draw matched me against two of the same players I had played in the previous tournament: Queenchess (who always wins) and A.N. Other11 (who recently always loses). the underlying pronblem is that I entered at 4kyu, and nobody entered at 2 or 3 kyu, so there were no beatable stronger players to target. As before, I am posting the defeat against Queenchess and inviting comments from stronger players. The other two games from Welwyn are also posted in case they may be of interest to players of 6kyu and weaker. There is another tournament this weekend. I have been feeling a little stronger recently, and will enter at the dizzy heights of 3 kyu instead of 4 kyu. I will not then spam the forum with more of my worthless games (just yet). The time limit this weekend is 35 minutes per player followed by sudden death, with AGA-style rules that require filling all the dame with the clock still running, which means there will be no time to keep records. For one thing, 5 minutes must be kept in reserve in case the opponent decides to play out all the ko threats with the clock running after the 'regular' dame have been filled. Here is the win by Queenchess. At least I made him think this time before the inevitable collapse when the multiple issues of life, death and connection overwhelmed my aging brain.

@thirdfogie, you are of course correct the result after the first danieleki is great for black, but you were wrong with one thing: white has 3 points not 2. ![]() |
