I felt similarly. Calvin seems good at getting an attack going, but maybe doesn't understand just how effective his prior moves have been and switches gears. Same at move 91 in top right of board later on. I would have kept up the pressure.

+1.

The degree to which F4 is strong is something I didn't appreciate until white played there. Certainly instead of this is the place. My play lacked severity in multiple places in this game, so I was lucky to win it. I was very disappointed that I missed B9, but playing inside to keep an opponent's weak group unsettled is something that is hard to judge as it can easily backfire when the opponent tries to escape. Guo Juan showed me some ways white could try to get out, and showed there decent responses for black, all of which I would have missed as they are almost tesuji, though a dan player sitting nearby said he would have seen them if he was looking for them but also admitted he wouldn't have considered white's resources either.

The upper right shape is one I would have punished earlier in a blitz game, but in a longer game, I psych myself out of it.

I think in longer games I am less enterprising and more careful, but in this case it was too careful.
