just wondering if my play was standard, or if there was a superior line. opponent was 19/12/0.8. other opponents were idiots.

i didn't want to call the donkbet and let the idiots in with their rags w/o even knowing anything more about the strength of the villains hand, and i obviously wasn't folding straight away, so i raised with the intention of folding to any further action.

as soon as i folded he said he had a flush draw, but i felt a set was a much larger part of his range given his passive stats and the fact that i had the A of clubs
