breakdown:

deepen: depth=1 val=1495 pv=[5b1>14] time=116.247µs total=116.736µs evaluated=71 tt=0 branch=71

The bot just completed its search to depth=1 plies. The value of the terminal position was val=1495, and the sequence of moves it found was pv=[5b1>14]. This iteration took time=116.247µs and the total time spent so far this move was total=116.736µs. We evaluated evaluated=71 board positions as part of the search, and we short-cut tt=0 positions by returning pre-computed responses from the hash table. This iteration searched branch=71 times more positions than the previous iteration (at one ply shallower)

stats: visited=1 scout=0 evaluated=71 null=0/0 cut=0 cut0=0(0.00) cut1=0(0.00) m/cut=0.00 m/ms=619.370822 all=0 research=2

We visited visited=1 nodes, in which we searched some children. Of those we searched scout=0 in "scout" mode, which means we did a less-detailed search to try to prove that they weren't relevant, instead of doing a full search to find the best move. null=X/Y We employed the null move heuristic in Y positions, of which we pruned X . We searched m/ms=619.370822 positions per millisecond.

cut/all/research are related to the alpha-beta search and likely not super relevant.

I could easily export other information --- what might be fun to visualize?
