hand 1- im at least potting it to sacre off any diamond chasers

hand 2- i'd probably fold cause at beast your up against ak so its a coinflip, i prefer avoiding those

Hand 3- i agree with kevster anything too big will scare him off and if you check i think he'll happily check behind you rather than raise you.

hand 4- i'd assume one of them had ace 2, probably mp2, but you have him covered by a lot so i'd probably push the turn here, where you checked.

Hand 5- would they maybe be playing something retarded like 67s or 78s or something, idk, i guess id probably call it while crying
