Lasker Open Round 3: Painful oversights and lucky escapes

The third round of the Lasker Open concluded Monday night with John and me fighting our match.
The first game started with an opening blunder can you spot how John could have punished me on move 9?

The position after 9. e4??
Hamlet faced Russel in his first game here and he was lucky to escape in game 1. In the diagram position below Russel threatened mate with 38. … Rg1 and after 39. Rc2 exd5 it was Hamlet who had the mating attack. Do you see how Russel could have built a deadly mating net with his 38th move?

David and Reagan reached the following position after a tough fight:

Reagan just played Kc3xc4. Kc2 didn’t offer much hope either. How should white continue?
Friday we meet for round 4 you can find pairings and standings here.
