Having never played this high, I don't feel like I can realistically offer my opinion, especially to a genius. However, I am curious as to a few things.
Stnd is no diff to a 1/2 game trust me. and genius is not the right word

$260 is significantly bigger than I would open to, but the way my table was playing was no-one else would put more than $200 in the pot without a mega premium hand, and the blind guy was calling 100%, calling near on 90% of flops and folding on near on 90% of turns - SO 1000 big blinds deep I had a pretty easy strategy to effectively print money as long as pots were HU. Normally I wouldn't pound on someone openeing blind so hard in attempt not to deter them from doing it but this guy was so arrogant I was having way too much fun just bashing on him

I personally think his entire value range is sets and he can have all 3 easily (although only one TT combo)
We have $10k back, anyone thought of bluffing ?

This genuinely crossed my mind
