im not sure if u knew it urself but i think they get slightly worse except for the last one which is horrific and will never succeed against a thinking opponent. the first two are fine and pretty hard to defend against so long as u play ur made hands the same way. the third is sure to get someone thinking because the turned K and rivered Q are pretty obvious cards to bluff and the flop is pretty dangerous for AK/AA so they might well expect u to check that river. the last IMO is horrendous and will never work against a good hand reader i'd suggest having the goods in the 4th situation and giving up otherwise
