Could be 44-QQ, in which case you have 58% equity. You are about 50% if you think he is not doing this with 88 or 99. You have 41% equity if you leave out 88 and 99 and add in SCs like 54, 65 and 76, but make it 33-QQ + the SCs and your over 50%. I'd say call since you're only calling $25 and there is already $64 in the pot, so you're getting better than 2:1, and you have 33% equity if there are at least a couple of overpairs 88-QQ in his range. Also, you can't bet this turn and put 50% of your stack in if you ever plan to fold. If you fold, it has to be check/fold turn.
