Baku wins this round, If Lalo really understand the "law" he will fold this round.
Frequently using the number close in range will risk a "Calamity". Cards that have been deprecated Aces, 2s, 8s, 9s. Possible future calamities :
Lalo's card : 15(1st round), 8(2nd round), 47, 63, 44
Baku's card : 25, 45, 26, 36(1st round), 39(2nd round). Its still safe for the next round I guess.
