hmmm ur pot committed, both call or fold are ok imho...
call - because your big 4bet sizing, also villain as u say has shown down 2 big hands and may of made a move as he wont of expected u to flat QQ..
fold - in terms of long term profit calling this type of players 5bet shove at these stakes with QQ wont exactly be your bread and butter profits, break even at best if your lucky
..
4bet smaller so u can build some bluffing frequency into different player types, then adjust according how u want to exploit them.. 2.1 to 2.5x there 3bet would be ok, in your situation 4betting anything around $20 to $23 would be fine..
4betting smaller for value will at least allow in theory the chance of your chosen victim to call or re-raise with worse hands than yours..
dont like your stats steve tbh, 12/7/4 is wee bit nitty for 6max, do u normally play this tight in 6max cash ??
if villain is half decent and has noticed how rarely u raise, then his 5bet shove maybe just AA, if u called and lost then heyho, afterwards now u know and u can adjust accordingly..
is the 3rd figure in the stats the 3bet % or the AF ?
