Although I normal tighten right up on the bubble the whole game had become very tight, so thought a small raise preflop would be good enough. If i hadn't hit top pair on flop I would have folded straight away if bet into. Villain had been playing pretty loose up until the bubble, and I certainly didn't put him on an overpair - so at least I got that right. Was I right to push on the flop though?

Push this preflop in my opinion, I don't think its debatable at all.

Thats awful, awful, awful. You're the short stack here and can't afford to play weak-tight poker like that. Push preflop and it isn't close.
