This depends a bit on runtime parameters. With default (faillow_early 0) this means that the best move at iteration 10 failed low at iteration 11. 11++ would mean, that the move fails high (with the aspiration search window, not with zero window, see below) >11t // PV changed working on 11 -- PV length was 11? This means, that this is a "true" PV, that was searched to end, and was inside the search window. >11t+ // ? The first move in the PV failed high in zero window search. A following "11t-" would mean, that this fail high could not be confirmed with a wider window. Well - a problem, I think we all don't like, but which happens >11. // full search depth 11 complete? Yep Regards, Dieter
