It is clear that stockfish has some fail low for e6-e5 at depth 2 because the score for Qg7-g3 is worse but stockfish never show a score that is worse than 1.05 for e6-e5 at depth 2


Depth 2 !?!?!?!

PV info in case of fail/high low is printed after 2 seconds of search because before is useless given that the correct resolved score is given just fractions of seconds later.

This is the actual code

Code:

                // Send full PV info to GUI if we are going to leave the loop or
                // if we have a fail high/low and we are deep in the search.
                if ((bestValue > alpha && bestValue < beta) || SearchTime.elapsed() > 2000)
                    pv_info_to_uci(pos, depth, alpha, beta);


This fail high/low infor could be sueful for analysis, but you don't analyse a position with 2 seconds time. Please avoid me the embarrass to read that _now_ also the first two seconds are important to you.
