PostPost subject: Odd Stockfish output?    Posted: Tue Mar 20, 2012 4:58 pm Reply to topic Reply with quote

The output from Stockfish-2.2.2 shown below seems odd to me. In particular, it appears that the engine has completed the depth 39 iteration and started the depth 40 iteration, but has only returned a lowerbound score for depth 39.

I don't recall seeing this behavior before, though it may be perfectly normal. In addition, I'm not seeing any further output from the engine, though it is still running. Anybody know what's going on here?
