So basically... yeah. A true upset. Toady pulled the mad string and win it all in the end from the one of the very bottom position.
This has been a situation I tried to avoid (to ensure the advantages for the leaders of earlier rounds) , hence is the reason why I added the limit "betting maximum half of your chips". Everybody not in top 3 is likely to go all out last round, creating a huge pool for the winner who also bet their all too, which that makes it even more easier to achieve an upset than it already is.
That said, there isn't much I can do this time. Toady bet his all on 5 character and got 1 of them, while the leaders bet around 15-20 and were rewarded with only 1 or 2 winning chips. The upset, as the result, lies in an acceptable range. And thus, my congratulation to Toady once again for being the very champion of ISML 2017 emerald casino~
