Has anyone had this happen before? - I just played a game where my opponent hit my bomb with his General. Not uncommon, of course, but he went on to hit the same bomb a couple of minutes later with his Major. Not content with that, after another two minutes, he went on to hit the same bomb with his Marshall.
I have a of theory here. Firstly, he thought he had hit a bomb somewhere in that area and wanted to check it was a bomb with his Major. Yes, it definitely was a bomb. After a couple more minutes he (or she) wanted to make absolutely sure it was a bomb, so checked again with his Marshall. No doubt about it. Now he knew for sure it was a bomb. There was no denying it after checking with three pieces.
It would interesting to know if that is a record, or if other players have been in games where their opponent has hit the same bomb multiple times. On a more serious note, I did feel sorry for the player as it is demoralising when you lose one large piece to a bomb. But that's the game.
Merry Christmas everyone
