1)Not sure whether to donk or c/j? Not really a fan of giving a free card, but then maybe its better to attempt to c/j here? Villain is pretty much unknown, running 37/23/3 (vpip/pfr/af) from 23 hands.
#1 I know small sample but he looks like he could keep barreling, and randoms do love to barrel here light, so I think I like the c/r on turn more.
I don't like ur sizing on the turn if you are going to donk, I'd try to make it look like we have a draw not a made hand and bet 1/3, that way we get his value hands and some spew to come over the top, whereas if you bet 2/3 he just flats or gives up.
Hand 1: I really like the lead ott, especially because people are using way too much that "pot control" idea and cb most turns to get 2 streets of value w/ 1 pair hands. Given that, I use pretty much this lead ott to avoid V to cb turn w/ hands he would call even both streets, but would prefer to pot control if possible.
If you check turn and V cb, I think you should go for the c/j otr, because V is either giving up oh the hand and is not calling a river bet or he has those kind of 1 pair hands that are trying to get value otr, and end up calling your raise a lot as your play doesnt makes much sense in their mind.
Hand 2: Everything seems pretty ok for me... just a cooler...
