Had a game yesterday where I played a bad evans gambit vs this bot, was down like 3 pawns for nothing, gave up a piece to prevent casteling and another to get fully developed, then he let me skewer his queen and king and give my last rook for 2 minor pieces, he then hung a rook by checking, a move I sadly overlooked at first, but was able to take it after a few moves exchanging the last minor pieces, I then play a move thretening to take the last rook, winning a pawn, he saved the pawn and lost the roock.
I've also noticed since I started practicing the St George defense that Walley apparently breaks and just give a bishop move 3 with e4, a6, d4, e6, Bg5, Qxg5 this happens I would say around 20% of the time, so it is quite consistent.
i've been playing this bot in the last recent days
its doesnt play at 1800 level and blunder pieces like the lowest rated bots
for example see this game:
https://www.chess.com/game/computer/58716449
he blundered a two bishops, rook and many pawns
i also notice that in some endgames wally would bring a bishop instead of a queen when advancing a pawn to another piece
i never seen such play from other bots such as isabel or boxbox
