[In the Wb Adapter] Engines, that are not specially prepared for the WB adapter, will show this problem. Nevertheless, to me it seems rather easy for the engine author to avoid this problem, when he is aware of the technical documentation of chessbase about he WB adapter. But there are many more problems in this environment. I.e. implementing learning features under the CB WB adapter is IMO an order of magnitute more difficult, than under the real WB of Tim Mann. It is doable. But doing this, cost much more time for me, than to make my engine work under WB. Then there is the pondering issue. Engines, that don't implement the CB specific ponder command, will have a disadvantage. But even engines, that implemented this (I am only aware of Gandalf and Yace, that implemented this) will have a disadvantage. The CB interface "lies" to the engine. It will make the engine search with ponder mode set and unset. With ponder mode set, probalby most enginse will allocate more time. This is (almost?) impossible under CB. Even if permanent brain is set, the WB adapter will tell the engine somtimes, that it shoud search, and no PB is set. Also, saving killer moves from one search to the other is much more complicated under CB, than under any other GUI. Sometimes, an WB engine may hang under CB without having a chance to do something against it. My engine Yace will hang, when it detected a 3-fold reption in the early game. It will send "1/2-1/2" to CB, (as defined in the WB protocol). But CB doesn't seem to respect this, and waits ... You may ask yourself, why I post this here. The reason is, that bug reports to CB are mostly ignored. I am not a customer of CB. Perhaps a few customers of CB will complain, and things might get better.
