Re: Exact TT scores and alpha/beta
Strangely doing PV TT-cutoffs in Stockfish causes a huge regression. You make the cut-off under the assumption that searching the node again would give you the same result as you found before, thus wasting time.

@Larry
Congrats with you improvements.

Re: re: win adjudication/Re: New Houdini
My theory of the strong engines having too many draws is that they simply outsearch most opponents, and they assume the opponent's will see the draw too.
