Retrograde pente puzzle
Posted: Mar 26, 2019, 10:46 PM

I'm trying to make some retrograde analysis pente puzzle. This is my first try:

Pente, tournament rules:

1. What was last move?
2. Please specify coordination of stones captured as last.






stone from F16 moved to D18

Very nice puzzle! My first thought didn't go far enough, my second thought was correct, my third was a second guess of my second thought and my fourth thought was to walk it out from K10 forward, which verified my second thought I sent you my solution.

I don't want to play non tournament rules games. If you take one of my unrated invites, play tourney

Next one:
1. Pente tournament rule. All moves was legal.
2. No information about captures
3. Its white move now.

Who has win in this position? Explain why?




I think this one is harder than previous one but I hope someone will try and give correct answer.
