Little Beast is a powerful bullet and blitz engine for slow computers! I developed the engine for my laptop playing at about 2500 kns on the game servers. The engine has a very fast search and an active playing style. The network is embedded. In my ENET-2023 test, the engine still manages 99 out of 110 solutions. If you play with a slow computer, you should choose aggressive openings and an aggressive style. Fast computers are stronger in positional play. In a short test with Ponder ON, Little Beast was able to stand up to Stockfish dev in Bullet 2 min + 0.1s
