Sorry. I realise I was poor with my wording. I don't normally like to write essays on video postings. However I dont see any major mistakes from scott here. Though he might not have considered each option when making these moves.
Ouwesok you were right when you commented on my QA game, and I said as such. Here I will try and explain why using a colonel here was not a bad idea.
11:18 that piece [sergeant] was stood next to a known luey (that a miner found earlier in the game). and it didnt take the luey at any point during the game. It's a reasonable bluff to call. The other two options aren't as good:-
-Let a likely lower ranked piece capture a miner and discover a major. This is bad because it exposes more pieces, and it will be easier for a (skilled) opponent to trap.
-Let a sergeant take two miners before revealing the luey. Also a bad idea because you lose two miners (you want to preserve those) and you give away information about your bomb structure.
Letting sergeant discover major/luey for two miners is a bad idea here. Therefore it's OK to take the piece coming down, which we deduced to be likely to be a bluff. If it isn't a bluff then...:-
-General is revealed: Assume colonel is protected by marsh. Go to right hand side and take the two moved pieces there. And likewise with a col for the piece next to col towards the middle.
-Marsh is revealed: take the col with gen.
12:56 Col is taken, so it's okay to lose general for info here.
personally I wouldn't have made that move. I would have retreated general from there and scouted it with a sergeant. However, it's not a disasterous move as we have compensation for the general if it is lost.
Why did opponent trade generals?
This was a serious blunder from rttrdm. Means you've lost a col AND your information advantage.
This principle applies to all situations, even the opening:-
-e.g. You scout a captain at the start of the game on I7. Trading captains with yours would be a terrible mistake. It means you lost a scout for nothing. You should either hit I7 (captain) with a higher piece, or hit J7 with your captain.
I think rttrdm was relying on his opponent hitting one of those two middle pieces. I don't think his intention was to try and exchange generals (but I may be wrong).
13:55 Known colonel attacking unknown
If a marshal WAS there, that would be the optimal play if he traded generals. If the marsh was there optimal play is to hit the col. It would make the position equal, or exchange the col disadvantage for a marsh disadvantage. Neither situation is bad for him. Since he didnt take after trading generals, we knew that piece can't have been the marshal, with over 95% certainty.
Deciding NOT to take the col, then immediately move down between a col and a possible spy, with Marshal would be a a very strange move from rttrdm. This was almost certainly not the case.
Revealing your marshal for a possible scouting piece is not a good idea.
