On 4th street you have 48 big blinds invested in a hand that has 3 outs that will win you the pot and 9 that might. I see villians range here as AdTd,AdXd, 6d7d, 2d3d, 44,55,TT, or air and because of the smaller turn bet I am leaning toward the first 2. Considering he has half his stack in the middle, you have no fold equity with a shove, so a shove here would be total spew.
1. Fold preflop unless you want to making more of these posts.
2. Bet/fold Flop
3. "It's definitely not a bad card for me, as now I can spike a J for the straight" = rationalization for bad call which profitable players love.
This is a huge leak.....
