Hand 1: Wow that is some fucked up bet sizing by your villian. Notice how he bet less on the river 'scare card'. I'd definately raise this here, but IMO you probably should have shipped it on the turn. I don't really like raising the flop all that much because he overbet and we need to at least get worse hands putting money into us on later streets since if we come over the top on the flop he may actually fold a weaker pair. Do you have any aggression stats or reads on this guy?

Hand 2: After bet/raise/call your hand is no longer looking so nice so definately fold here. Of course after opening preflop with KT here you can't fold to that donks min raise with the muiltiway action. Just look to flop 2pair+ otherwise dump the hand. A pair with this hand multiway is almost never good, especially with all the action.
