Baku's plan here is ingenious. Not only is he forcing Lalo to waste air as well, but more importantly, he's managed to force Lalo's next card, although I don't know if he himself can recognize that (it's Baku, he probably did).
This game is shaping up to be something of an inverse to the tower gamble. We as the viewers know more than the players, and yet the question remains trying to follow their thought process. What an exciting game!
