First it checks each move with pn-search for easy mates, and finds that e3e5, f4g3, d4xd5, h2g1, and h2g3 all lose simply. Then the regular search takes 6 seconds to finish a 2 ply deep search, and favors Qxe6 with pv: e3xe6 g5xf4 d4xf4 f7xe6<q d3xd5<q d6xd5<q c4xd5<q e6xd5<q h2xg2<q h7xg7<q <q means the move was in the qsearch. after another 3 seconds it finished searching 3 ply deep and favored g8=Q with a huge score. This move remained the favorite for the next 4 ply until I got bored and stopped it after ply 7 and 630 seconds. pv at ply 7 was g7g8q h7xg8 e7e8q g8g7 f4e5 d5xe5 e3xe5 e6xe5 e8xe5 g5f6 etc Angrim
