Result:

2 other moves !

With Ponder play Crafty move 19 in
0:0257 (bad time controling with ponder)
And without ponder Crafty play this move
19 in 5:24 !!!

This is an good example for my opinion !

Pros and Cons for Ponder and for not Ponder !

The other move is move 25 !
OK not relevant for this match !

In the analyses for move 19 you can see
that crafty will play Kh8 (more than 10
sec.) !!

Of course not enough analyses, but I make
this analyses with many programs and I can
not see that ponder is 50-100 ELO !

Not more than 20-40 ELO (ponder = off) and
10 ELO for an other time manangment !

Time managment ...
Good example move 16 and 17 !

I see not problems in the Crafty time managment
without ponder !!

In move 24 use Crafty more time with ponder
and play the identical move !

I mean that Crafty play in this game better
without ponder, because move 19 play Crafty
in an bad time for an move with ponder = on !

I think that I have in an eng-eng game 5 other
moves with ponder on. But this 5 moves which
the engines play without ponder must not been
bad !

Kind regards
Frank
