I called with KQs for 35 BB because I thought I could have decent equity against lower pocket pairs and possibly dominate some weaker hands, given how often he was shoving.
He had A2o and won. Was calling the right or wrong play here?
Because you felt that KQs competed very well with the bulk of his jam range, and you're not exactly wrong. He is jamming every 4th hand so we can assume his jam range to be 25% or the top 25% of hands, or more likely he is not thinking of how good the hand is, but probably simplifying it (maniacs are lazy) by just jamming all of Ax and all pocket pairs (not necessarily the best 25% of hands but Ax and pocket pair have best showdown value pre-flop). 21% of all hole card deal combos are pocket pairs or contain an A. Yep, close enough to 25% that this is probably what he is doing. Can you say LAZY?? : P
So, if we wish to stay ahead of most of his range, we could start by cutting that in half, say A8 and up (fold A7 and down) or any pocket pair 88 or higher to call him. Or to be safer be a bit tighter with the Aces, maybe AT or AJ or higher, and maybe even lower pocket pairs down to 66 or 55. This would give us a significant range advantage. But there are no guarantees in a single hand of course.
Now, I have seen players far better than I post on forums like this that they will call down maniacs like this with any pocket pair or almost any A and they do well but that is probably in cash games, not tournament play. But there is nothing wrong with tightening right up so long as we are not entering icm stack depths. I wouldn't tighten up to AA KK AK only, that would be too tight, but A8s and up, AJo and up, 88 and up. Work with that, adjust that as you like.
Now if he's jamming 50%, 75%, 100% you can call him quite wide, any A, any pair, probably any 2 broadways.
But of course also make sure that you have isolation. If you are closing the action, awesome! Let it rip! But if there are players still to act after you call, then you need to be super tight because if you call down with A8 and the player on your left has AK ... you beat the maniac but lose to the tight player who happens to have it.
If the maniac is on your right, then everyone else at the table is still to act (unless it folds to him on SB). This sucks so we might have to just be super tight, fold a ton and let someone else take him down.
