Hey, I managed to play headsup in turbo tournament, 1st place 780$ or 460$ 2nd place.
I'd like to get some ideas or maybe some mathematical approach/advise on a marginal hand, that might be overplayed by me.
Throughout all FT he was not too actively, 3handed he minraise/folded a couple of times, other than that nothing "fancy" or overly loose/tight.
Opponent wasn't too much out of line, he had 20BB and I started headsup with 10BB, first hand he shovs K2o, I call K5s and we split.
Now the key hand:
I pick up Q7o and decide to shov, since I assume he'll fold more often than not. Minraise+fold is out of question to me in that scenario, because we aren't deep enough and it could be exploited too easily (for example he might not call a shov with 109s, but reshov to minr.)
What are your thoughts on Q7o? To me it appears to be borderline, eventually he had K8s, called and I lost, but as we all know it's not about that.
Was shoving "wrong" and is it clear fold or is shoving "ok" given stack sizes?
P.S. If he shoved 20BB and I hold Q7o with my 10 BB, I fold for sure.
