Avoid sending info strings before 'uci' has been received Do not send the following info string on the first call to aligned_ttmem_alloc() on Windows: info string Hash table allocation: Windows large pages [not] used. The first call occurs before the 'uci' command has been received. This confuses some GUIs, which expect the first engine-sent command to be 'id' as the response to the 'uci' command.
