At 10nl and down yeah I think 7x and 56s can take this line, thinking we have overpair and won't fold. But I think at 25nl these hands are much less likely to jam, if you're opening 44 utg then your stats must be reasonably wide so this guy should expect to see you turn up with 78s 88 77 TT often enough for him to realise that 56 and A7 are not the nuts. I guess it's possible this guy has you tighter, ie TT+ AQ+ or something like that, in which case A7 is a lot stronger. Bean, how are your stats shaping up here utg?
