Flop and turn looks very standard but i dont know what is the best river play. Only draw that missed there is JT. What should be our river play? Betting big doesnt make sense at all with this hand. We hit flush on the river but there is not alot of worse hands he can call with and we have probably the worst possible flush. There are two options i can think off xb or bet small like 1/3 maybe even smaller? If we bet it probably has to be b/f right?
