not following you here did you have qq and opened for 4 times the big blind and the other player came over the top if so thrn you have to decide has he got u dominated with kk or aa or are you racing against ak its poker you got to gamble im pushing
I assume that in most cases the range of your opponent is of such a hand as: AA, KK, QQ, JJ, AK !!! much less often (and depending on how aggressively you played before), this is 1010.99, AQ, - more often this hand will call !!!
So in this case a shove only if I had a pair of AA?
you still have enough chips to continue to fight for first place, but if you are ready to risk that, most likely, 20 <80 AA and KK or 50/50 in the case of AK, then good luck))) I think that at the final table after raising 4bb, a very narrow reraise range !!!! a wider range can afford either (fish) or (chip leader) - with enough chips to risk !!!
