-----

• Looking back, maybe 3bet sizing was too small
  
• Flop - I thought villain has some bluffs in his x/r range (Axs) but leans heavily to his value (AA, sets)
  
• Turn - Solver still has 72% call for my range (and 62% for AQs). Against this villain, I'm okay with the fold. But why is solver still calling so often in this spot?
