Pre is a standard call IMO

I think I'd rather raise flop than turn. As there's a lot of bad turn cards which either improve villains range to beat us, or scare cards for villains range. So we want to build the pot when we have (basically) the nuts on the flop. Raising turn also always looks stronger.

River: Obviously never folding. At these stakes I think the shove is probably better than calling as I expect villain to be making a weird value bet with an over pair/AK/ weak 2 pair some of the time. However, given the connectivity of this board, I'm not shocked to see villain show up with a flush here. JT,J9,T9,QJ, AT, A9, 67, A7 of spades etc all make sense

Pre: Standard.

Flop: We're going to have our opponent drawing dead here very often and when we raise we're going to get a heap of folds so I like the call IP.

Turn: Despite our raise looking strong here I think it is our best option. Villain can have c-bet a ton of Kx on the flop and we want to set up the hand to play for stacks if possible. I would go a bit larger here though, around $1.50-$1.60.

River: Pretty awkward spot here when villain donks into us. The runner runner flush is obviously not all that likely but it's hard to imagine villain donking out here with random Kx hands. I'm torn between flat calling and jamming here, given how odd villains line is I definitely don't mind the jam but it is possible calling is better here.

At these stakes I can't see that calling the flop will have better Ev than raising. Tons of pair plus draws out there. Not only that but there's 1/4 of the deck which puts a four straight on the board either giving us a losing hand or killing our action.

On the river I would just call once the flush comes in. I would have expected him to reraise a smaller set on the turn rather than take this line.
