Subject: Chess and 2bit EGTBs (win/loss/draw info only)

If I wanted to play with EGTBs with only win/loss/draw information and no
DTM/DTC information where would I place the probe code in the search routine?
Taking crafty as an example it has the TB probe code placed next to the hash
table probe code and if the current position is in a TB file it returns
immediately because is has perfect/complete information. But with 2bit/entry
EGTBs it just doesn't seem right to place the code there. It seems logic to me
to place the TB probe code in the evaluation function and if a leaf node is in a
2bit/entry TB file give it a bonus. Another possibility would be to place the TB
probe code before calling the qsearch.
Could someone tell me if I'm thinking correctly?

Best regards,
Alvaro Cardoso
