Hi Mark


>Thought I better repost this move since apparently you did not see it.

Sorry I didn't catch your last message. This has already happened to me
several times. Really sorry. I thought you were on vacation...


>See if Radio Shack can cause Tiger to use 10 seconds more clock time...
>For Tiger, is this version 11.4 ?

In fact this game has been played with Chess Tiger version 11.1 thru
11.4, as I work on the program every day...

All the moves played in May were played by 11.4.


Tiger 11.4 plays:
51...Qg2+ (time=0.49s, score=+17.32, time left=10.12s)

Tiger has not been able so far to compute deep enough to see the forced
mate...

There was a mate in 6 in the position begining with 51...Qf3+. Tiger
would have seen it with a little more time (4 seconds to announce mate
in 7, 34 seconds to find it is mate in 6).
