[A_PLUS]

Checking a made flush happens a lot, way more than you would expect. They can't believe how lucky they got when it comes, and the slow-play instinct which is so finely tuned with them kicks in, so they check (believing it is the only way to double up).

Once again, not saying that it is a flush, but dont discount it. You see players checking rivered flushes playing limit, where it makes even less sense.

Im in the check behind camp. They arent calling a large bet here without a very specific group of hands (AA,KK, AQ) that we are beating. I think you will see a checked flush (or str8) more often than a calling hand we beat
