Body: <p>Houdini Chess engine is said to have a calibrated evaluation in which engine scores correlate directly with the win expectancy in the position. A +1.00 pawn advantage gives a 80% chance of winning the game against an equal opponent at blitz time control. At +2.00 the engine will win 95% of the time, and at +3.00 about 99% of the time. If the advantage is +0.50, expect to win nearly 50% of the time.</p>
  
  <p>Looked around the net but couldn't find a table? Ideally I'd like to see material difference calculator where I would plug in "1 pawn and 1 knight" down.. what is my win/loss expectancy. </p>
