for starters, its shove or fold. With 22k and a 3k starting pot, you should be shoving preflop with 7-1 pot/stack odds
. I would really need a good read that the maniac was indeed strong to fold, any doubt at all and it is time to shove. With tens you only have 2 outs twice to improve at all (another reason to shove preflop here) so there is no point in calling, if you are ahead you shove, if you are behind you fold. With two limpers in front of you, 10's is a good enough hand to shove PF with at that part of the tournament. Closer to the bubble, I like the shove even more. You could pick up a 5k (3k +2limps) pot without a flop.
