2013 Ohio State-Interesting Positions

Postby Chexhero on Sat Sep 14, 2013 9:37 am

Here are some of the most interesting positions that occurred for me in the Ohio State Open.

Red-Mark Sokolovsky White- Joe Moore

Red to Move and Draw!

This position is a PP draw shown in Basic Checkers. Mark Sokolovsky replied 16-20 which loses. Try completing the loss. Then, go back and try to complete the draw for red. Feel free to post solutions.

Red- Alex Moiseyev Whte- Joe Moore

White to Move and Draw!

I thought Alex M would have replied 11-16 the previous move, which seems to win for red. He replied 3-7, which surprised me. I replied 30-25, which loses. 31-27 is another move however, that draws for white. There are actually 3 very cool ways white can force a draw after 31-27. I will post one of the ways.

31-27, 13-17, 22-6, 15-31, 23-18, 31-24, 32-28, 2-9, 28-19, 9-13, 19-15 Draw! Try to find the other two ways white can force the draw!


Red- Joe Moore White-Louis Cowie

Red to Move and Draw!

This is another classic pp draw. I have studied it about 30 times in Basic Checkers. Guess what? I resigned! For some reason, for about the last 10 moves of the game, I was convinced there was something different about the position and it was not that same draw I studied over and over again. Instead of playing it out, I gave up and gave a free game away. So now you get to do what I was not able to do and find the draw!


Red-Joe Moore White- Rich Beckwith

Red to Move and Win!

I think I confused Rich this game and was why I was able to arrive at this winning position, though it should be pointed out that I had made a losing move earlier in the game. Fortunately for me, Rich did not play it right. However, I replied 7-11, which turns out to be a very strong position for white. There is a shot for red that I missed. See if you can find it!

Those are some really nice positions Joe. I have been able to play the Brooklyn shots a few times but the classic draw position you had with Cowie I remember only playing once in tournament play:

Yea, I can't really explain it... Any master class player whether they know the pp or not is going to see that man down draw in the Cowie game. Not so much I couldn't see it, I just gave up too soon. I was so focused on what I thought I did wrong, and not what I could still do right. But, I will just need to make sure it never happens again. Glad you enjoyed the positions :)
