Hand 1: Put him on a turn calling range and then I'll offer more detailed comments. List the actual hands.

Hand 2: Do the same thing here on the river.

Hand 3: Put him on a more realistic flop shoving range and refer to this: http://www.flopturnriver.com/phpBB2/...in-t87954.html If that was anywhere close to his real shoving range then you wouldn't be saying your c-bet was marginal.
