hey ich started playing PLO100 a few weeks ago and im still learning a lot of basics, so please be patient with me ;)

here i 3bet a pretty week regular in position. i decide to cbet the flop. afterwards i think its better to check behind here, not only because of his c/r, but to take my free card and evaluate the turn.

my coach said when i bet the flop here i have to call the raise too and see what he will be doing on the turn and then reevaluate. i decided to fold, but im kind of lost overall in that hand. 

i only have 200 hands from villain so far and he plays 50/24 with 8% 3bet and hes got an overall check/raise flop of 6% (2 out of 35)

so how do you play in general here?
