       Q4 g and j

       Hi!
       I'm not sure I understand the solution for games g and j in
       question 4.
       In particular: what is "the a minor extension" for game g?
       Finally, I'm probably wrong but I see a contraddiction in the
       solution for j: at the beginning we delete column 3 because it's
       strictly dominated if column player mixes between 2 and 4 with
       probability q > 5/7.
       Then we delete the bottom row and we discover that now column 2
       is strictly dominated by 4.
       Fine. But this means that the player is not going to choose
       column 2, so the probability we assign to this column is now 0.
       But 0 < 5/7, so we cannot say that column player mixes between 2
       and 4... Isn't it a contraddiction?
       Thank you very much!!!
       Federico

       For (g), maybe my reply below (Topic Q4) helps?
       For (j)
       No, that's not a problem. The point of ITERATED elimination of
       strictly dominated strategies is exactly that:
       - you find a strategy that's strictly dominated by ANY other
       strategy -> it will never be played by a rational player -> get
       rid of it
       - you do not have to worry about strategies that you have
       eliminated at an earlier point
       - it doesn't matter if you won't play the dominating strategy in
       the end in equilibrium
       Here specifically, you'll see that column 3 will be SD by 4
       alone now (after having eliminated the bottom row), so you don't
       have to worry about column 2 now. It was only necessary in the
       first place to get rid of column 3, before you could delete the
       bottom row.
