I thought this was the most difficult Everyman for a while.  Thanks to this thread for some insights into 23a.  I saw the game-related word but didn’t think it could be right... there’s a fine line between “cleverly cryptic” and “hamfisted” isn’t there?
Was slightly held up by putting the wrong fish in 9ac for a while.  There’s a species that’s something of an evolutionary anomaly that works perfectly for the second half of the clue, but I couldn’t get the wine out of the first half.
