Two hands from a live heads-up tornament for comment

[splittter]

Against a player who I consider to be better than me, so beforehand I'd decided I'd be happy to play for all the chips in a 50/50 situation ... indeed, that was probably my best chance.

Hand 1

Both about even (i have a slight lead), playing maybe 35 mins. I'd been the more agressive, but not by much ... no huge pots yet. Biggest hand when we'd both shown down top pair of Queens, I'd won with a better kicker. No all-ins yet.

Hand 2

After that set-back I'd gotten more agressive, bluffed all-in on a few raggedy looking flops ... but also gone all-in on the river, after I'd slow played top pair of queens on the flop, which had turned into a full-house by the river. My opponent folded (river also put a 3-flush on board), but made it clear she thought I was bluffing and that she was ahead. That had gotten me back into a very slight lead.
